Step-by-step explanation:

$\sf t^3 - r + 20 \div r$

What expression represents '' five times the quotient of some number and ten"? A.5(z/10) B.5(z-10) C.5(10/z) D.5(10-z)

maw [93]

Answer:

Option A is correct

$5(\frac{z}{10})$

Step-by-step explanation:

Let the number be z.

Given the statement:

'' five times the quotient of some number and ten"

" quotient of some number and ten" translated to $\frac{z}{10}$

"five times the quotient of some number and ten" translated to $5 \times \frac{z}{10}$

Then, the expression we get,

$5(\frac{z}{10})$

Therefore, $5(\frac{z}{10})$ expression represents '' five times the quotient of some number and ten"
