Answer:

I got 9.

Step - By - Step Explanation:

7x - 13 = 5x + 5

7x = 5x + 18

2x = 18

x = 18 ÷ 2 = 9

x = 9

7(x) - 13 = 5(x) + 5
7x - 91 = 5x + 25
7x - 5x - 91 = 25
2x - 91 = 25
2x = 25 + 91
2x = 116
x = 58

Can someone solve this for me please.

Answer:

  • The value of PR is 21 ft.

Step-by-step explanation:

<u>We know that:</u>

  • 3(PQ + QT + TP) = PR + RS + SP
  • PQ = 7 ft.
  • QT = 4 ft
  • RS = 12 ft.

<u>Work:</u>

  • 3(PQ + QT + TP) = PR + RS + SP
  • => 3(7 + 4 + TP) = PR + 12 + SP
  • => 21 + 12 + 3TP = PR + 12 + SP
  • => 21 + 3TP = PR + SP
  • => 21 + SP = PR + SP                                                                       [3TP = SP]
  • => 21 = PR

Hence, <u>the value of PR is 21 ft.</u>

Hoped this helped.
