April is going to the bakery to purchase donuts and cinnamon rolls for the office personnel. She must purchase at least 30 items. She has collected only $30, so total cost must be no more than $30. If d represents donuts that cost $0.75 each and r represents cinnamon rolls that cost $1.25 each, which system of inequalities can be used to represent the region for the number of donuts and cinnamon rolls April could purchase
Answers
Answer:
d + r ≥ 30
$0.75d + $1.25r ≤ $30
Step-by-step explanation:
Given the following :
Number of items to purchase = atleast 30
Total cost must be no more than 30
cost of donut (d) = $0.75
Cost of cinnamon (r) = $1.25
Number of donuts and cinnamon to purchase
To total number of items :
Donut + cinnamon ≥ 30
d + r ≥ 30
Cost of items to purchase :
Cost = price per item * number of items
$0.75d + $1.25r ≤ $30
Six times a number plus 3 equals three times the same number minus
nine. What is the number? Hint: Let x= a number. Create the expression for

in the word problem.
Answers
Answer:
x = -4
Step-by-step explanation:
Six times a number plus 3 equals three times the same number minus
nine. This equation is 6x + 3 = 3x -9. Next, solve this equation and you get -4. Plug in -4 for x and you should get -21 on both sides.

Step-by-step explanation:
The slope of the line is -7/4
Answer:
= -7/4
Step-by-step explanation:
When we have 2 points, we can use the slope formula
m = ( y2-y1)/(x2-x1)
= ( -14-7)/(9- -3)
= ( -14-7)/(9+3)
= -21/12

Darryl left the White House and traveled toward the ferry office at an average speed of 25 mph. Some time later Jacob left traveling in the opposite direction with an average speed of 35 mph. After Darryl had traveled for four hours they were 170 mi. Apart. How long did Jacob travel?
Answers
Answer:
2 hours
Step-by-step explanation:
Given the following :
Darryl :
Speed = 25mph
Jacob:
Traveled in opposite direction
Speed = 35mph
After Darryl had traveled for 4 hours, Distance between them was 170 miles
Distance traveled by Darryl :
Speed * time = (25 * 4) = 100 miles
Total distance = distance traveled by Darryl + distance traveled by Jacob
170 miles = 100 miles + distance traveled by jacob
Distance traveled by Jacob = 170 - 100
Distance traveled by Jacob = 70 miles
Time = distance / speed
Time traveled by Jacob = 70 miles / 35mph
Time traveled by Jacob = 2 hours

-8-5n=64+3n
Answers
Answer:
n= -9
Step-by-step explanation:
The calculator is correct haha, You're welcome.
n=-9
Explanation:
In order to solve for x, we must get x by itself on one side of the equation.
The equation is:
-8-5n=64+3n
5n is being subtracted and the inverse of subtraction is addition. Add 5n to both sides of the equation.
-8-5n+5n=64+3n+5n
-8=64+3n+5n
-8=64+8n
64 is being added and the inverse of addition is subtraction. Subtract 64 from both sides of the equation.
-8-64=64-64+8n
-8-64=8n
-72=8n
n is being multiplied by 8. The inverse of multiplication is division. Divide both sides of the equation by 8.
-72/8=8n/8
-72/8=n
-9=n
The solution to the equation is n=-9

Answer:
14. d
15. b
Step-by-step explanation:
steps for #14:
1. complementary angles are angles that equal 90 degrees when added together. so, those two angles equal 90. make an equation to represent this.
(x + 5) + (x - 9) = 90
2. combine like terms.
2x - 4 = 90
3. solve for x.
2x = 94
x = 47
4. plug x into both formulas to find the measurements of each angle.
47 + 5 AND 47 - 9
d. angle DFG = 52, angle JKL = 38
steps for #15:
1. when angles are linear pairs, it means they equal 180 degrees when added together. so, these two angles equal 180. make an equation to represent this.
(x - 39) + (x + 61) = 180
2. combine like terms.
2x + 22 = 180
3. solve for x.
2x = 158
x = 79
4. plug x into both formulas to find the measurements of each angle.
79 - 39 AND 79 + 61
b. angle 1 = 40, angle 2 = 140

A square garden has an area of 100ft^2. What is the perimeter of the garden?
Answers
Given:
The area of a square garden = 100 sq. ft
To find:
The perimeter of the garden.
Solution:
Let the side of the square garden be a.
Area of a square = [tex]a^2[/tex]
So, [tex]a^2=100[/tex].
Taking square root on both sides.
[tex]a=\pm \sqrt{100}[/tex]
[tex]a=\pm 10[/tex]
Length of side cannot be negative. So, a=10. It means, side length of the garden is 10 ft.
Perimeter of square = 4a.
Perimeter of square garden is
[tex]4(10)=40[/tex]
Therefore, the perimeter of the square garden is 40 ft.

Step-by-step explanation:
Cassidy wrote the linear equation y = 5 x + 4. Then, she wrote the equation of the line that is parallel to y = 5 x + 4 and that passes through (8,–2). If her new equation is in the form y = 5 x + b, what is the value of b?
Answers
Answer:
b=−5x+y
Step-by-step explanation:
Let's solve for b.
y=5x+b
Step 1: Flip the equation.
b+5x=y
Step 2: Add -5x to both sides.
b+5x+−5x=y+−5x
b=−5x+y
Denise has 3 hours to spend training for an upcoming race. She completes her training by running full speed the distance of the race and walking back the same distance to cool down. If she runs at a speed of 8mph and walks back at a speed of 2mph, how long should she plan to spend walking back?
Answers
Answer:
Denise should plan to spend 36 minutes walking back.
Step-by-step explanation:
Let 'x' reflect the amount of time spent running in hours, then 3-x represents the time spent walking in hours.
here , we know,
[tex]Distance= Speed \times time[/tex]
Given the values ,
[tex]Distance= 8x[/tex]
[tex]speed=2mph[/tex]
[tex]Time=(3-x)hours[/tex]
Now , putting these values ,
[tex]8x=2(3-x)[/tex]
[tex]8x=6-2x[/tex]
[tex]10x=6[/tex]
[tex]x=\frac{6}{10}[/tex]
[tex]x=\frac{3}{5}[/tex]
[tex]\frac{3}{5} \times 60[/tex] = 36minutes (converting hours into minutes that is 1 hour = 60 minutes )
Hence , the answer is 36 minutes .
The number of burritos Delainy ate on Tuesday is the same as the number of burritos Louie ate on Wednesday. On Tuesday, Delainey ate 16 more than 1/2 the total number of burritos consumed. On Wednesday, Louie ate 1 less than 3/4 of the total number of burritos consumed. Write an equation to determine the total number of burritos consumed. Hint: let x = # burritos consumed.
Answers
Answer:
The total number of burritos consumed is 68 and an equation to determine the total number of burritos consumed is [tex]\frac{1}{2}x+16=\frac{3}{4}x-1[/tex]
Step-by-step explanation:
Let x be the total number of burritos consumed
We are given that On Tuesday, Delainey ate 16 more than 1/2 the total number of burritos consumed
So, Number of burritos ate by Delainey on Tuesday=[tex]\frac{1}{2}x+16[/tex]
We are also given that Louie ate 1 less than 3/4 of the total number of burritos consumed.
So, Number of burritos ate by Louie on Wednesday =[tex]\frac{3}{4}x-1[/tex]
We are given that The number of burritos Delainy ate on Tuesday is the same as the number of burritos Louie ate on Wednesday.
So, [tex]\frac{1}{2}x+16=\frac{3}{4}x-1\\1+16=\frac{3}{4}x-\frac{1}{2}x\\17=\frac{x}{4}\\68=x[/tex]
Hence the total number of burritos consumed is 68 and an equation to determine the total number of burritos consumed is [tex]\frac{1}{2}x+16=\frac{3}{4}x-1[/tex]
