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:

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