The perimeter of the rectangle below is 102 ft. What is the value of X
The perimeter of the rectangle below is 102 ft. What - 1

Answers

Answer 1
Answer: Perimeter = length of all sides added together

102=(3x+5)+(3x+5)+(7x-4)+(7x-4)

102=2(3x+5)+2(7x-4)

102=6x+10+14x-8

102=20x+2

102-2=20x

100=20x

x= (100)/(20)

\left[\begin{array}{ccc}x=5\end{array}\right]

Answers

The total price including 7 percent tax on a $9.79 purchase is $10.67

What is percentage?

A percentage is a number that tells us how much out of 100 and can also be written as a decimal or a fraction.
