Answer:
x = 3.4375
Explanation:
Write out the equation for area of a rectangle with the numbers.
(9.6x + 7) × 2.5 = 100
Distribute 2.5 through the parentheses
24x + 17.5 = 100
Move the constant to the right hand side and change its sign
24x = 100 - 17.5
Subtract the numbers
24x = 82.5
Divide both sides of the equation by 24 to get your answer
x = 3.4375
Hope this helped! And good luck!
