5q greater than or equal to 8q -3/2

5q ≥ 8q - 3/2

Add 3/2 to both sides.

3/2 + 5q ≥ 8q

Subtract 5q from both sides.

3/2 ≥ 3q

Multiply both sides by 2.

3 ≥ 6q

Divide both sides by 6.

0.5 ≥ q.

The value of q is less than or equal to 0.5.

in problems involving proportions, we can use cross products to test whether two ratios are equal and form a proportion. to find the cross products of a proportion, we multiply the outer terms, called the extremes, and the middle terms, called the means.
