Answer:

19 red beads

Step-by-step explanation:

We first need to find a common denominator of 4/9, 1/5 and 1/4.

The common denominator is 180. Like in an expression, what we do to one side we have to do to the other.

Silver - 180/9 = 20 ; 20*4 = 80 so there are roughly 80 sliver beads.

Gold - 180/5 = 36 ; 36*1 = 36 so there are roughly 36 gold beads.

Blue - 180/4 = 45 ; 45*1 = 45 so there are roughly 56 blue beads.

180 - (silver+gold+blue) = red beads

180-161 = 19 red beads b/c ----->

80+36+45+19 = 180

Choose all equivalent expression(s).
ElenaW [278]

<u>Given</u>:

The given expression is a b^{-3 x}

We need to determine the equivalent expression.

<u>Equivalent expression:</u>

Let us determine the equivalent expression.

The equivalent expression can be determined by simplifying the given expression.

Hence, let us apply the exponent rule to simplify the given expression.

Thus, applying the exponent rule, a^{-b}=\frac{1}{a^{b}}, we get;

a(\frac{1}{b^{3x}})

Rewriting the expression, we get;

a(\frac{1^{3x}}{b^{3x}})

Simplifying, we get;

a\left(\frac{1}{b}\right)^{3 x}

Thus, the equivalent expression is a\left(\frac{1}{b}\right)^{3 x}

Hence, Option C is the correct answer.
