Answer:
32
Step-by-step explanation:
3x+1=8x-24
25=5x
x=5
3 times 5 plus 1 is 16 and so the length is 32
comment section:
XM=MY because MN is segment bisector
XM=3x+1=3*5+1=16=MY and since XM+MY=XY 16+16=32
Answer: 36
Step-by-step explanation:
6/2= 3 & 3x2=6 & 27/9=3 & 3x9=27 so you would multiply 3x12=36 so you would just multiply. and I'm a 6th grader.
Step-by-step explanation:
t=2+5×j
j=5
t=2+5×5
t=27
Answer: y=5x/2 - 2.5
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(-2.5-2.5)/(0-2)
m=-5/(-2)
m=5/2
y=mx+b
y=5x/2 + b
-2.5=5(0)/2 + b
-2.5=0 + b
b=-2.5
y=5x/2 - 2.5
