Question

Math PLEASE HELP IM SO CONFUSED IM ATTACHING THE SLIDES!!!!

Answer 1

• x = 19, TS = 22

Explanation:

• Use ratios to solve for x. Corresponding sides have same ratio.

Q1

• (x + 5)/30 = (36 - 20)/20
• (x + 5)/30 = 16/20 = 4/5
• 5(x + 5) = 4(30)
• 5x + 25 = 120
• 5x = 95
• x = 19

Q2

• (5x - 2)/(3x + 1) = 39/26
• (5x - 2)/(3x + 1) = 3/2
• 2(5x - 2) = 3(3x + 1)
• 10x - 4 = 9x + 3
• 10x - 9x = 3 + 4
• x = 7

TS = 3x + 1 = 3(7) + 1 = 22
