Answer: The number is 1.
Step-by-step explanation:
create the formula from the problem
4x -7 = 1
move the seven to the other side by adding seven to both sides
4x (+7) -7 = 1 (+7)
4x = 8
then to get the x by itself, divide both sides by 4
4x/4 = 8/4
x = 2
You can check your work by plugging the x back into the original problem
4 (2) -7 = 1
8 -7 = 1
1 = 1 (this means it is correct)
V = LXHXW
V = 12X20X8 = 1920
12(2)+5
