This is a ratio problem. If dry ing : water = 5 : 2, what is water when dry ing = 15?

The new ratio is 15 : water. How do we get from the first ratio to the new one? We multiply by 5. Meaning, we also need to multiply the 2 quarts of water by 5, giving us 10 quarts of water.

Solve the inequality

mafiozo [28]

Answer:

$\large\boxed{q\geq-8}$

Step-by-step explanation:

$7q-5\leq10q+19\qquad\text{add 5 to both sides}\\\\7q\leq10q+24\qquad\text{subtract 10q from both sides}\\\\-3q\leq24\qquad\text{change the signs}\\\\3q\geq-24\qquad\text{divide both sides by 3}\\\\q\geq-8$
