Answer:
Question #1 choice A x=3, ST=24 and Question #2 choice C x =12
Step-by-step explanation:
Question #1
T midpoint so ST=TU and 8x = 2x+18
8x =2x+18
8x-2x=18
6x=18
x=18/6
x=3
so ST= 8x=8*3=24
choice A
Question #2
M midpoint of AB so AM=MB and 4x+1=7x-35
4x+1=7x-35
1+35=7x-4x
36=3x
36/3=x
12=x
choice C
You add 13 to each side of the equation.
Then the equation says ' q = 0 ', and
you immediately recognize that as its
solution.
