If a varies directly as b, and a = 28 when b = 7, find b when a = 5.
Reika [66]

Answer: Option B.

b=\frac{5}{4}

Step-by-step explanation:

If a varies directly with b then when a increases b it also increases by a factor k.

Then we can write that

a = kb

We know that when a = 28 then b = 7. So

28 = k * 7

k=\frac{28}{7}

k=4

Therefore the equation of proportionality is:

a=4b

So when a=5  then:

5=4b\\\\b=\frac{5}{4}
