It is the last choice or #3 or a C.
Answer:
x=9
Step-by-step explanation:
All measurements of the interior angles equals up to 180 degrees when added together, therefore add them all together and set it equal to 180.
7x+2+4x+7+8x=180
-Combine like terms
19x+9=180
-Subtract 9 on both sides
19x=171
-Divide by 19
x=9
14x0.75=10.5
15-10.5=4.5
so she will get $4.50c
Hope this helps! :D

The sum of 4 and the quotient of a number and 11 = <span>4 + (y ÷ 11)</span>
the difference of 4 and the product of 11 and a number = <span>4 – 11y
</span>4 more than the quotient of a number and 11 = <span>4 + (y ÷ 11)
</span>4 more than the quotient of 11 and a number = 4 + (11 ÷ y)
