Question

1. the rectangle in the diagram provided has a perimeter of 7y + 91 centimeters. 6a which of the following equations represents the perimeter in terms of y? the correct option was c 7y + 91 = 7y + 11 7y + 91 = 7y + 18 7y + 91 = 14y + 28 c 7y + 91 = 10y + 48 5 nailed it! 6b solve the equation found in part (a) for y. enter your next step here

Explanation:

Step1: Start with the equation

We have the equation \(7y + 91=14y + 28\).

Step2: Subtract \(7y\) from both sides

Subtracting \(7y\) from both sides gives \(91 = 7y+28\).

Step3: Subtract 28 from both sides

Subtracting 28 from both sides: \(91 - 28=7y\), which simplifies to \(63 = 7y\).

Step4: Divide both sides by 7

Dividing both sides by 7: \(\frac{63}{7}=y\), so \(y = 9\).

Answer:

\(y = 9\)
