4 x 7 = 30 - x.

What is the value of x ?

x = 2

Step-by-step explanation:

Given

4 x 7 = 30 - x

First solve the left side . When you multiply, we have

28 = 30 - x

Combine like term. When -x crosses over equality sign , it becomes positive x , and 28 becomes -28

So ,

x = 30 - 28

x = 2

2 over 5

step-by-step explanation:

the 2: 3 ratio is the length of the ac segment to the cb segment total length. this implies that the ratio between segment ac length and segment ab length is 2: 5. point c is 2/5 from a to b, so the required fraction is 2/5.
