A 12 foot rope is cut into two pieces so that one piece is 3 feet less than twice the length of the other piece. How long is each piece?
What is 5 & 7?
12 = A + B
A = 2B - 3
Substitute the value of A from the second equation into the first.
12 = (2B-3) + B
Add
12 = 3B-3
Add 3 to each side
15 = 3B
Divide each side by 3
5 = B
If B is 5, then A must be 7.
Double Check b/c Mary's work isn't always right.
A (which is 7) is 3 feet less than twice B (which is 5)
7 = (2 x 5) - 3
7 = 10-3
7 = 7

A trapezoid with an area of 48m has a height of 6m. One of the bases is 12m. Solve the equation to find the length of its other base.
What is 4m?
A = (1/2)h(B+b) where A is area of the trapezoid, h is height, B is one base, b is the other base, therefore
48 = (1/2)6(12+b)
48 = 3(12+b)
48 = 36 + 3b
3b = 12
b = 4
the other base is 4m
