3/5 of the total responses expected = 87...
3/5x = 87
x = 87 / (3/5)
x = 87 * 5/3
x = 435/3
x = 145 <=== what was expected

Answer:
The answer in the procedure
Step-by-step explanation:
we have
we know that
The formula to solve a quadratic equation of the form
is equal to
in this problem we have
so
substitute in the formula
Here's how to find the value of x:
<span>9 - 0.75 ( x + 8 ) - 5 = -6.5 find the difference of 9 - 0.75
</span><span>8.25 ( x + 8 ) - 5 = -6.5 add 5 to both sides
</span>
8.25 ( x + 8 ) = -1.5 distribute 8.25 to x and 8
8.25x + 66 = -1.5 subtract 66 from both sides
8.25x = -67.5 divide both sides by 8.25
x = 18.18181818...... the value of x is 18 2/11
hope this helps
