If x represents the number of dimes, then 2x will represent twice the number of dimes. This is the number of quarters, since there are twice as many quarters as dimes.

There are 6 more nickels than dimes, so the number of nickels is 6 more than x. It is (x+6).

If we use the monetary values in cents, then the total of all coins is ...

25(2x) +10(x) + 5(x+6) = 485 . . . . . . matches choice D

How do you solve to get y?

dmitriy555 [2]

Answer:

y = 64

Step-by-step explanation:

Using the rule of logarithms

• $log_{b}$ x = n ⇔ x = $b^{n}$

Given

$log_{y}$ 4 = $\frac{1}3}$ , then

4 = $y^{\frac{1}{3} }$

Cube both sides

4³ = ( $y^{\frac{1}{3} }$ )³, hence

y = 64
