Hey there! :-)

Let the unknown number be s.

"half of a number" means we divide s by 2.

We write it like so:

\frac{s}{2}

Now, the problem says that we subtract 7:

\frac{s}{2} -7=14

  • s/2-7=14
  • s/2=14+7
  • s/2=21
  • Multiply both sides by 2:
  • s=42

Therefore, the number is 42. Hope this helps! :)

  • If 7 is subtracted from half of a number, the result is 14.
  • Let the number be x.
  • Therefore, by the problem
  • \frac{x}{2}  - 7 = 14 \\  =  >  \frac{x}{2}  = 14 + 7 \\  =  >  \frac{x}{2}  = 21 \\  =  > x = 21 \times 2 \\  =  > x = 42

<u>Answer:</u>

<u>The </u><u>number </u><u>is </u><u>4</u><u>2</u><u>.</u>

Hope you could get an idea from here.

Goryan [66]
I believe the answer is 3/8. The whole portion of employees, which is translated as 8/8 is deducted by 5/8, which is the population of male employees.

Which choice is equivalent to the quotient shown here when x&gt;=0 square root of 35x^5 divided by the square root of 7x^3
natita [175]

Answer:

x√5 = x square root 5

Step-by-step explanation:

√35x^5 ÷ √7x^3 = √(35x^5 / 7x^3)

√(35x^5 / 7x^3) = √(5x^5 / x^3)

√(5x^5 / x^3) = √5x^(5-3) = √5x²

√5x² = x√5
