Answer: The distance from each side of the bench to the edges of the platform = 16.85 feet.
Explanation:
Length of platform = 40.75 feet
Length of bench = 7.05 feet
Let the distance from each side of the bench to the edges of the platform be x
So, it becomes x+7.05+x = 40.75
⇒2x+7.05= 40.75
⇒2x = 40.75- 7.05
⇒x = 33.7
⇒x=
⇒x= 16.85 feet .
So, the distance from each side of the bench to the edges of the platform = 16.85 feet.
Answer:
Given that,
R = 3x + 9y
Also, given that,
y = 6
R = 7
We have to find the value of x
For that, you can to put 6 and 7 to the equation instead of y and R respectively.
R = 3x + 9y
7 = 3x + 9 × 6
7 = 3x + 54
7 - 54 = 3x
- 47 = 3x
Hope this helps you :-)

Steps to solving equations:
Simplify/combine the like terms
Isolate the variable (Get the variable on one side
Solve for the variable
-2y - 7 + 5y = 13 - 2y Simplify/Combine terms
3y -7 = 13 - 2y Isolate variable by adding 2y to both sides
5y - 7 = 13 Add 7 to both sides to get y alone on one side
5y = 20 Divide by 5 on both sides to solve for y
y = 4
You can check your answer by replacing y with 4 in the original equation.
Answer:
15x - 40 = 8
Step-by-step explanation:
3/4x-2=2/5
Multiply each side by 4*5 or 20
20 (3/4x-2=2/5)
15x - 40 = 8
