8 0

Answer:

x = 20

Step-by-step explanation:

We can cross multiply to isolate x

\frac{8}{12} = \frac{x}{30}

multiply 30 from both sides

\frac{30*8}{12} = x

simplify and we get

20 = x

Which pair of numbers have a greatest common factor of 7?
ella [17]
<span>The GCF is the number that is a factor of both (or all) of the numbers of a given set and which is the biggest factor of this kind (often the smaller number of the two)

7 and 14 have a greatest common factor of 7.

 28 and 7 also have a GCF of 7, so the first two responses fit.

21 and 3 have a GCF of 3, so that isn't correct.

7 and 1 have a GCF of 1, so that's incorrect as well.</span>
