Step-by-step explanation:
7(x - 3) = 4(x + 5)
7x - 21 = 4x + 20
3x = 41
x = 13.67
Let's solve your equation step-by-step
7(x-3)=4(x+5)
Step 1:Simplify both side of the equation
7(x-3)=4(x+5)
(7)(x)+(7)(-3)=(4)(x)+(4)(5) (Distribute)
7x+-21=4x+20
7x-21=4x+20
Step 2:Subtract 4x from both sides
7x-21-4x=4x+20-4x
3x-21=20
Step 3: Add 21 to both sides
3x-21+21=20+21
3x=41
Step 4: Divide both sides by 3
3x/3 =41/3
Answer: x=41/3

A car used 1 2/5 gallons of gasoline to travel 50 3/4 miles. How far can the car travel on 1 gallon of gasoline?
Answer:
36 1/4
Step-by-step explanation:
you had to divide the miles into gallons
A car can travel [tex]36\frac{1}{4}[/tex] Miles on 1 gallon of gasoline.
What is an improper fraction?A fraction that has the numerator higher than or equal to the denominator is said to be an improper fraction.
Given, a car used [tex]1\frac{2}{5}[/tex] gallons of gasoline to travel [tex]50\frac{3}{4}[/tex] Miles.
In order to solve the problem:
First, we solve covert the mixed fraction to improper fraction.
That means,
[tex]1\frac{2}{5}[/tex] = 7/5
[tex]50\frac{3}{4}[/tex] = 203/4
That means, a car used 7/5 gallons of gasoline to travel 203/4 miles.
To find the distance of car can travel on 1 gallon of gasoline:
203/4 ÷ 7/5
= 203/4 x 5/7
= [tex]36\frac{1}{4}[/tex] Miles.
Therefore, car can travel [tex]36\frac{1}{4}[/tex] Miles on 1 gallon of gasoline.

if a translation take triangle CAT to C’A’T’, what is A’T’?
Answer:
Option (1)
Step-by-step explanation:
If a translation takes the triangle CAT to triangle C'A'T', transformation will be the rigid transformation or Isometry.
By the definition of rigid transformation, shape and size of the image and preimage remains the same.
Therefore, length of the sides of ΔC'A'T' will remain same as ΔCAT after the translation.

A purse contains a collection of quarters, dimes, nickels, and pennies. The average value of the coins in the purse is 17 cents. If a penny is removed from the purse, the average value of the coins becomes 18 cents. How many nickels are in the purse?
Answer:
There are total of 17 coins in the purse
Step-by-step explanation:
Let x represent the no of coins in the purse
Let y represent the total amount
y/x = 0.17
y = 0.17*x............................(i)
y-0.01 / x-1 = 0.18
y - 0.01 = 0.18x -0.18........(ii)
We substitute y = 0.17 x into the second equation:
0.17x - 0.01 = 0.18x - 0.18
0.17 = 0.01x
x = 17
Hence, there are total of 17 coins in the purse

Select all equations that are equivalent to (5x+6)2=3−(4x+12) .
a. 5x+6=3−(4x+12)
b. (5x+6)2=−4x−9
c. 52x+3=3−(4x+12)
d. (5x+6)2=−4x+15
e. 5x+6=−8x−18
Answer:
B
Step-by-step explanation:
ita only b .............
The equations that are equivalent to (5x + 6)2 = 3-(4x +12) is (5x+6)2=−4x−9.
Option B is correct.
The very first thing to do is to solve the expression in the given question.
SO,
(5x + 6)2 = 3-(4x +12)
Open brackets
10x + 12 = 3 - 4x - 1210x + 12 = -4x - 9Collect like terms
10x + 4x = -9 - 1214x = -21x = -21/14
Now, we will solve each of the given options to determine which one corresponds to the solution to the expression above.
Starting with Option (a)
5x + 6 = 3 - (4x + 12)
Open brackets
5x + 6 = 3 - 4x - 125x + 6 = -4x - 95x + 4x = -9 - 69x = -15x = -15/9Option (a) is incorrect
b.
(5x + 6 )2 = -4x - 9
Open brackets
10x + 12 = -4x -9Collect like terms10x + 4x = -12 -914x = -21x = -21/14Option (b) is correct
(c.)
52x + 3 = 3 - (4x + 12)
Open brackets
52x + 3 = 3 - 4x - 1252x + 3 = -4x - 952x + 4x = -9 - 356x = - 12x = -12/56x = -3/14Option (c) is incorrect
(d)
(5x + 6)2 = -4x + 15
Open brackets
10x + 12 = -4x + 1510x + 4x = -12 + 1514x = 3x = 3/14Option (d) is incorrect
(e)
5x + 6 = -8x - 18
Collect like terms
5x + 8x = -18 - 613x = - 24x = -24/13Option (e) is incorrect
Therefore, we can conclude that the correct equation equivalent to the given expression in the question can be seen in Option b.

101.5² - 100.5² = (101.5 - 100.5) * (101.5 + 100.5)
101.5² - 100.5² = 1 * 202

In 2016, the cost of 2 ounces of pure gold was $2,640. Complete the double number line to show the cost for 1, 3, and 4 ounces of gold.
Answer:
1 would be 1320
3 would be 3960
4 would be 5280
Step-by-step explanation:
The cost of 1, 3 and 4 ounces of gold in 2016 was $1,320, $3,960 and $5,280 respectively.
Cost of 2 ounces of gold in 2016 = $2,640
Cost of 1 ounce of gold in 2016 = Cost of 2 ounces of gold in 2016 ÷ 2
= $2,640 ÷ 2
= $1,320
Cost of 3 ounces of gold in 2016 = Cost of 1 ounce of gold in 2016 × 3
= $1,320 × 3
= $3,960
Cost of 4 ounces of gold in 2016 = Cost of 1 ounce of gold in 2016 × 4
= $1320 × 4
= $5,280
Therefore, the cost of 1, 3 and 4 ounces of gold in 2016 are $1,320, $3,960 and $5,280 respectively.

17.) You want to purchase 4 board games that are $15 each. There is a 6% sales tax. What is the
total amount of your purchase?
Answer:
$63.60
Step-by-step explanation:
4 board games are $15 each, multiply 4*15 = 60.
There is a 6% sales tax, so it is 6% extra. To calculate 6% as a decimal, divide it by 100, so 6/100 = 0.06. Now that it is 0.06 extra, you add 0.06 to 1.00 because 1.00 is the 100% of the price (the $60). So now it is 1.06 of the price. Multiply 60 * 1.06 and you get $63.60
Answer:
60.36 cents
Step-by-step explanation:
you have to times 60 by .6 then you get 36 and that is how much taxes cost.
