Multiply the fractions 9 over 7 × 63 over 81

1 answer:

8 0

(9/7) x (63/81) = 567/567 = 1.

This was found by multiplying the first numbers (from each fraction) together and then the last numbers (from each fraction) together and putting a / between them. The simplification step was done by finding they are the same. This means that they always multiply to one.

Solve: −3(5+8x)−20≤−11

Tatiana [17]

-3(5 + 8x) - 20 ≤ -11 |use distributive property: a(b + c) = ab + ac

-15 - 24x - 20 ≤ -11

-35 - 24x ≤ -11 |add 35 to both sides

-24x ≤ 24 |change signs

24x ≥ -24 |divide both sides by 24

x ≥ -1
