the numerator of a certain fraction is four times the denominator. If 10 is added to both numerator and denominator the resultin
1 answer:
Okay so will have x be the denominator.
Numerator: 4x
Fraction:
which would be equivalent to 4.
If you add 10 to both the numerator and denominator the resulting fraction is
We multiply both sides of the equal side sign times (x + 10) we get...
4x + 10 = 2 * (x + 10)
4x + 10 = 2x + 20
4x - 2x = 20 - 10
2x = 10
x = 5 < denominator
4x = 4 * 5 = 10 < So the fraction is 10/5

<h2 /><h2>Answer: 18</h2><h2>~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~</h2><h2 />First we need to substitute the value of the variable into the expression.
=
.
Now we need to solve .
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
First, calculate 3 to the power of 2 and get 9.
Multiply 2 and 4 to get 8.
Subtract 5 from 8 to get 3.
Multiply 3 and 3 to get 9.
