I guess you could....it depends on how big the concrete block is
Answer:
See below in bold.
Step-by-step explanation:
1. x/8 = 15/24
Cross multiplying:
24x = 8*15
x = (8*15)/24
x = 5.
2. 5/6 = 35/x
5x = 6*35
5x = 210
x = 210/5
x = 42.
3.<em> </em>18/42
Divide top and bottom by 6:
18 / 6 / 42/6
= 3/7.
4. 15/75
Divide top and bottom by 15:
= 1/5.
Four times a number plus twenty one
Answer:
x = 22
Step-by-step explanation:
I interpreted your problem as:

I simplified the problem to:

I combined like terms:

I moved all x to one side and all other constants to the other:

I divided by 3/2 (1.5) on both sides to isolate x:
