Answer:
x = 27
Step-by-step explanation:
Both angles together form 180 degree.
Set your formula up as
180 = (5x+2) + (x + 16)
180 = 5x + 2 + x + 16
180 = 6x + 18
180 - 18 = 6x
162 = 6x
162/6 = x
27 = x
Answer:
a) 2(x+12) and 2 times X+ 2 times 6
b) 12y+8
Step-by-step explanation:
for (A) the equation that i choose are the distributed from of the equation
for (B) I combined like terms and they only equation that made sense is this one
Answer:
C. C is the only one that is rational out of all of them. The rest are irrational
For this you need to expand the brackets first:
3(2x+5)-4(2x-7) = 6x+15-8x-28
And then now you need to add and simplify:
6x+15-8x-28 —> 6x-8x= -2x
15-28= -13
So that leaves
-2x - 13
