Miguel needs 1/2 gallons of milk to make 12 milkshakes. How much does he need to make 42 milkshakes?

he needs 17/8 gallons of milk to make 30 milkshakes and this is proportional relationship

Step-by-step explanation:

3/4 divided by 12 = 1/16

gallon to make 1 milkshake and

1/16 x 30 = 17/8 gals. to make 30 milkshakes,

it's proportional because 3:4 > 15:8

answer: (c) m∠qpo + (2x + 16)° = 180°

step-by-step explanation:

the opposite angles of a quadrilateral are supplementary.

so, ∠o + ∠q = 180°   and   ∠p + ∠r = 180°

since ∠r = 2x + 16°, we can use substitution as follows:

∠p + ∠r = 180°

∠p + (2x + 16)° = 180°
