27. 6(10+n)=6.10+6.n
29. 5.x+5.7=5(x+7)
31. 10t+10.3=10(t+3)
27 is 6
29 is 70
31 is 60
those are all of the answers.
Answer:
A
Step-by-step explanation:
X=7
So first add them all up
x-2+2x+x+3=4x+1
4x+1=29
4x=28
x=7
x is 130 degrees. y is 80 degrees.
Part A: c = 2.25 + b
Part B: c = 6.75, b = 8
hope this helped!
