Answer:

5 1/4

Step-by-step explanation:

Speed = distance / time

21 / 2 = 10.5

10.5 = distance / 0.5

distance = 10.5 x 0.5 = 5,25 miles or 5 1/4

Vadim26 [7]

Answer:

The greatest common factor is 6.

Step-by-step explanation:

Greatest common factor is 6. If you use the distributive property then the answer would be 6(4) + 6(6) or 6(4+6). Then you distribute the 6 to each digit and should get 24+36.

This set notation really seems the hard way to exclude a single value. Anyway...

The domain doesn't include where the denominator is zero, 4x + 7 = 0,

x = -7/4

The range doesn't include the asymptotic value, which is

y=2x/4x = 1/2

So we need domain x ≠ -7/4 and range y ≠ 1/2

Answer: First choice

If it takes 16 yards of material to make 5/2 costumes, how much material will be needed to make 19/2 costumes of that same size?
IRISSAK [1]

yards/costumes:16/(5/2) = X/(19/2)

Cross multiply.

(5/2)x = 152

Multiply both sides by 2/5.

x = 101 1/3 yards
