Answer:
Addition and subtraction are inverse operations. Start with 7, then add 3 we get 10, now subtract 3 and we get back to 7.
Another Example: Multiplication and division are inverse operations. Start with 6, multiply by 2 we get 12, now divide by 2 and we get back to 6.
Answer:
x = 20
Step-by-step explanation:
4x and 5x are same- side interior angles and sum to 180° , then
4x + 5x = 180
9x = 180 ( divide both sides by 9 )
x = 20

Answer:
1. h = 12/b
2. h = 8 in
Step-by-step explanation:
Part 1
Use the formula for the area of a parallelogram:
A = bh, where b- length, h - height
Since the area is constant, 12 in², the formula for the height is:
bh = 12
h = 12/b
Part 2
If b = 1.5 in, the height is:
h = 12/1.5 = 8 in
The height is too much compared to the base, this is because the area is fixed and the height gets greater if the base gets smaller.
The height and base are inversely proportional.
