what is the algebraic equation 3 times the sum of a number and 7 is 2 less than five times the number

stealth61 [152]

Let n = number

"3 times the sum of a number and 7" translates to 3(n + 7)

"2 less than five times the number" translates to 5n - 2

The word "is" becomes the equals sign.

3(n + 7) = 5n - 2

I think you already asked this one.

Answer:

Rational

Step-by-step explanation:

$2^{-3}$ simplifies to $\frac{1}{8}$ .

Therefore, it is rational.

$2^{-3}\\\\\text {Apply negative exponent rule: } a^{-n} = \frac{1}{a^n} \\2^{-3}= \frac{1}{2^3}\\ \rightarrow 2^3 = 2*2*2=8\\\boxed{2^{-3}=\frac{1}{8}}$
