Answer:
Jill = 125lb
Pete = 175lb
Eddie = 157lb
Ken = 140lb
Step-by-step explanation:
Given
Represent Jill with J; Ken with K; Pete with P and Eddie with E
[tex]J = K - 15[/tex]
[tex]P = 50 +J[/tex]
[tex]E = P - 18[/tex]
[tex]J + K + P + E = 597[/tex]
Required
Determine the weight of each
Substitute 50 + J for P in [tex]E = P - 18[/tex]
[tex]E = 50 + J - 18[/tex]
[tex]E = J + 50 - 18[/tex]
[tex]E = J + 32[/tex]
Make K the subject in [tex]J = K - 15[/tex]
[tex]K = J + 15[/tex]
Substitute [tex]K = J + 15[/tex], [tex]E = J + 32[/tex], [tex]P = 50 +J[/tex] in [tex]J + K + P + E = 597[/tex]
[tex]J + J + 15 + 50 + J + J + 32 = 597[/tex]
Collect Like Terms
[tex]J + J +J + J = 597 - 32 - 50 - 15[/tex]
[tex]4J = 500[/tex]
[tex]J = 500/4[/tex]
[tex]J = 125lb[/tex]
Substitute 125 for J in [tex]P = 50 +J[/tex]
[tex]P = 50 + 125[/tex]
[tex]P = 175lb[/tex]
Substitute 175 for P in [tex]E = P - 18[/tex]
[tex]E = 175 - 18[/tex]
[tex]E = 157[/tex]
Substitute 125 for J in [tex]K = J + 15[/tex]
[tex]K = 125 + 15[/tex]
[tex]K = 140[/tex]

A vehicle uses 1 1/8 gallons of gasoline to travel 13 1/2 miles. At this rate, how many miles can the vehicle travel per gallon of gasoline?
Answer:
12 miles
Step-by-step explanation:
The problem above is related to the topic on "Equivalent Ratios." The missing term above is "the number of miles that the vehicle can travel per gallon of gasoline." In order to find this term, you have to use the "cross products."
Let n be the missing term.
[tex]1\frac{1}{8} gallons[/tex]/[tex]13\frac{1}{2} miles[/tex] = [tex]\frac{1 gallon}{n}[/tex][tex]\frac{9}{8} gallons[/tex]/[tex]\frac{27}{2} miles[/tex] = [tex]\frac{1 gallon}{n}[/tex][tex]\frac{9}{8}[/tex] x n = [tex]\frac{27}{2}[/tex] x 1 gallonn = [tex]\frac{27}{2}[/tex] ÷ [tex]\frac{9}{8}[/tex]n = [tex]\frac{27}{2}[/tex] x [tex]\frac{8}{9}[/tex]n = 12 milesTherefore, the vehicle can travel 12 miles per gallon of gasoline.
Answer:
12 miles per gallon of gasoline
Step-by-step explanation:
1 1/8 gallon of gasoline = 13 1/2
9/8 gallon of gasoline = 27/2 miles
1 gallon of gasoline 8 times 27/9 times 2 miles
1 gallon of gasoline = 216/18
1 gallon of gasoline = 12 miles
Hence,the car can travel 12 miles per gallon of gasoline
The rate of traveling is 12 miles per gallon

Rita and Lumiere are solving a problem about driving to Scream N Barf theme park... They know that the theme park is 30 miles away and that they will drive an average of 15 miles per hour. They need to write an equation and solve it to find out how long it will take to get there.
Rita says they should the formula `d=rt`, where `d` is the distance traveled in miles, `r` is the rate of speed in miles per hour, and `t` is the time in hours.
Lumiere says they should use the equation `t=\frac{d}{r}` instead. Who is right? Explain.
9514 1404 393
Answer:
Lumiere
Step-by-step explanation:
Rita is correct that the relation between distance, speed, and time is given by ...
d = rt
Since they want to find the time, they would have to solve this equation for t, which would give ...
t = d/r . . . . Lumiere's equation
Lumiere has the most direct approach.
Answer:

B. 22 cm2
C. 44 cm?
D. 154 cm2
Answer:
d)154 cm²
Step-by-step explanation:
πr²
22/7 ×7² cm²
22×7
154cm²
The approximate area of the given circle is 154 square centimeter. Therefore, option D is the correct answer.
What is area of a circle?The area of a circle is the space occupied by the circle in a two-dimensional plane. Alternatively, the space occupied within the boundary/circumference of a circle is called the area of the circle. The formula for the area of a circle is A = πr², where r is the radius of the circle.
From the given figure, radius of a circle = 7 cm.
Now, area of a circle = 22/7 ×7²
= 22×7
= 154 cm²
Therefore, option D is the correct answer.

Jerry earns a base salary of 350 per week plus an 8% commission on all sales at his job. Which inequality shows the minimum amount in cells s Jerry must make to earn more than a 500 in a week .
Answer:
D
Step-by-step explanation:
8% in decimal form is written out as 0.08, so right away the answer is either C or D.
Then if you have "s" = 1875, you would get:
350 + (0.08 × 1875) = 500
That would mean any number greater than 1875 will give you a total more than 500.
Therefore the answer is D.
There are 800 ppl who 50% of them use english 30% use spanish 15% vianameese 5% other
how many people use each language?
(WORK whoever shows the best work gets brainiest reported if no work!)
Answer:
People who use English language = 400 people
People who use Spanish language = 240 people
People who use Vianameese language = 120 people
People who use other language = 40 people
Step-by-step explanation:
Total people = 800
People who use English Language = 30%
People who use Spanish Language = 30%
People who use Vianameese Language = 15%
People who use other Language = 5%
We need to tell how many people use each language
People who use English language:
It can be found by calculating 50% of 800
Solving:
[tex]50\%\: of\: 800\\=\frac{50}{100}*800\\=400[/tex]
So, People who use English language = 400 people
People who use Spanish language:
It can be found by calculating 30% of 800
Solving:
[tex]30\%\: of\: 800\\=\frac{30}{100}*800\\=240[/tex]
So, People who use Spanish language = 240 people
People who use Vianameese language:
It can be found by calculating 15% of 800
Solving:
[tex]15\%\: of\: 800\\=\frac{15}{100}*800\\=120[/tex]
So, People who use Vianameese language = 120 people
People who use other language:
It can be found by calculating 5% of 800
Solving:
[tex]5\%\: of\: 800\\=\frac{5}{100}*800\\=40[/tex]
So, People who use other language = 40 people
Mary, Bianca and Steve are picking apples. Mary picks 264 apples. 1/6 of these apples are green. Bianca picks 150 apples. 28% of these apples are green. Steve picks 340 apples. 15% of these apples are green. Who picks the most green apples? You must show your working out in your workbooks.
Answer:
Steve picked most green apples among the three people.
Step-by-step explanation:
Given that:
There are three persons Mary, Bianca and Steve who are picking apples.
Few of the apples are green.
We have to find the person who picked the most number of green apples.
Let us first calculate the number of green apples picked by each one of them then we can compare the three values to find the required answer.
Total number of apples picked by Mary = 264
Number of green apples picked by Mary = [tex]\frac{1}{6}[/tex] of the total apples picked by Mary = [tex]\frac{1}{6}\times 264 = 44[/tex]
Total number of apples picked by Bianca = 150
Number of green apples picked by Bianca = 28% of the total apples picked by Bianca= [tex]\frac{28}{100}\times 150 = 42[/tex]
Total number of apples picked by Steve = 340
Number of green apples picked by Steve = 15% of the total apples picked by Steve = [tex]\frac{15}{100}\times 34 = 51[/tex]
We have 3 numbers now, 44, 42 and 51.
Clearly 51 is greatest of them all.
Therefore, Steve picked the most green apples.

Step-by-step explanation:
Eli and Claire work at a dry cleaners ironing shirts. Eli can iron 15 shirts per hour,
and Claire can iron 20 shirts per hour. Eli and Claire worked a combined 17 hours
and ironed 300 shirts. Graphically solve a system of equations in order to determine
the number of hours Eli worked, x, and the number hours Claire worked, y.
Answer:
∴ Eli worked for 8 hours and Claire worked for 9 hours
Step-by-step explanation:
Let us form the two equations then graph them
∵ Eli worked for x hours
∵ Claire worked for y hours
∵ Eli and Claire worked a combined 17 hours
∴ x + y = 17 ⇒ (1)
∵ Eli can iron 15 shirts per hour
∵ Claire can iron 20 shirts per hour
∵ They ironed 300 shirts together in 17 hours
→ Multiply x by 15 and y by 20, then add the products and equate their
sum by 300
∴ 15x + 20 y = 300 ⇒ (2)
Now let us find 2 points in each equation and draw the two lines which represent the two equations
→ In equation 1, put x = 0
∵ x = 0
∵ 0 + y = 17
∴ y = 17
∴ The first point is (0, 17)
→ Put y = 0 and find x
∵ y = 0
∴ x + 0 = 17
∴ x = 17
∴ The second point is (17, 0)
→ In equation 2, put x = 0
∵ x = 0
∵ 0 + 20y = 300
∴ 20y = 300
→ Divide both sides by 20
∴ y = 15
∴ The first point is (0, 15)
→ Put y = 0 and find x
∵ y = 0
∴ 15x + 0 = 300
→ Divide both sides by 15
∴ x = 20
∴ The second point is (20, 0)
Draw the first line using points (0, 17) and (17, 0)
Draw the second line using points (0, 15) and (20, 0)
The graph is attached down
From the graph
The red line represents equation (1)
The blue line represents equation (2)
The two lines intersected at point (8, 9) which is the solution of the system of equations
∴ The solution of the two equations is (8, 9)
∴ Eli worked for 8 hours and Claire worked for 9 hours
