Adalyn used 2.5 yards of fabric to make 3 decorative pillows. If she makes 12 pillows, how many yards of fabric will she need?

Step-by-step explanation:

if Adalyn use 2.5 yards to make 3 pillows

than for 12 pillows she will use  (2.5yards x12)/3=10 yards

you can see it with a different approach as well

2.5 y3 pillows

5 yards6 pillows

7.5 yards9 pillows

10 yards12 pillows

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°

its 50 miles away from the starting point
