Answer:
x = 2
Step-by-step explanation:
-4(3 - 2x) + 2x = 2 x 4
-12 + 8x + 2x = 2 x 4
-12 + 8x + 2x = 8
-12 + 10x = 8
-12 + 12 + 10x = 8 + 12
10x = 20

x = 2
2/5 as
5 - 7/1 - 6 = -2/-5. Dividing a negative number by a negative gives you a positive so 2/5.
(-2)^4=16
(-2)^-1=-1/2
-1/2x16=-8
Answer: -8
16ft= 192 in
8ft= 96 in
192/36= 96/16 = 6
Your drawing is 1/6 of the actual billboard
The correct equation is 8.7 + b = 54.6
because it is given that measure of side a is 8.7cm, in all other equations the values of a is different.
from the first equation we can find the value of b, that is
b = 54.6 - 8.7 = 45.9
so, value of b is 45.9cm
