Consider the proportions m/n=1/2 and n/k =2/5. what is the ratio m/k? explain your

If the m/n = 1/2, that means that m = 1 and n = 2

If the n/k = 2/5, that means that n = 2 and k = 5

Which gives us that m/k = 1/5 .

(f - g)(x) = 5x^3 - 3

step-by-step explanation:

rearrange these functions vertically, with like terms in separate columns:

f(x) = 5x^3 - 2

g(x) =         +1

now subtract, column by column:

(f - g)(x) = 5x^3 - 3

i got 10.28 but that rounds up to 10.3
