Question

Use the number line​ below, where RS = 4y+4 ​, ST=3y+4 ​, and RT=43. a. What is the value of​ y? b. Find RS and ST.

Ignore the equation on the top just use the number line

Answer 1

Answer: a. y=5

b. RS=24, ST=19

Explanation:

a. RT=RS+ST

43=4y+4+3y+4

43=4y+3y+4+4

43=7y+8

7y=35

y=5

b. RS=4y+4

RS=4(5)+4

RS=20+4

RS=24

ST=3(5)+4

ST=15+4

ST=19
