0.12 rounded to the nearest tenth is 0.1
Answer:
x = 10
Step-by-step explanation:
To find x, write a proportion between the side lengths for the similar triangles in the figure.

To solve, cross multiply and isolate x.
(x+5)(12) = 18(x)
12x + 60 = 18x
60 = 6x
10 = x
7a + 10 = 2a subtract 2a from both sides
-2a -2a
5a + 10 = 0 subtract 10 from both sides
-10 -10
5a = -10 then divide both sides by 5
/5 /5
a = - 2
