Let x=bob’s original amount of money
Let 9x=Bessy’s original amount of money
9x+4=5(x+4)
9x+4=5x+20
4x=16
x=4
9(4)=36
Bob had $4 before earning $4 and Bessy had $36 before earning $4

Answer:
Step-by-step explanation:
Remark
Choose any number at all and see what happens.
Suppose x = 8
3*(8 + 1) = 3*8 + 3
3(9) = 27
3*8 + 3 = 24 + 3 = 27
What you have shown is that the second choice is incorrect. There is at least one value that makes the equation correct (that is, both sides come to the same result.)
If choice two is false then choice one must be true since these results may give the only 2 possible results.
15/8 would be the slope u have to subract
Answer:
480 ft^3
Step-by-step explanation:
We can calculate the volume of the sculpture with the data they give us in the statement.
The volume would be the multiplication between the length, width and height, that is:
v = l * w * h
we know that l = 12 ft; w = 5 ft; h = 8 f, replacing:
v = 12 * 5 * 8
v = 480
in other words, the volume of the sculpture is 480 cubic feet, therefore 480 color blocks are needed because its volume is 1 cubic foot.
