Answer:
16
Step-by-step explanation:
3/4y-7=5
*multiply both sides of the equation by 4
= 3y-28=20
*move <u>constant</u> to the right-hand side and change its sign
=3y=20+28
*add the numbers <u> </u>
=3y=48
*divide both numbers by 3
and that's how you get 16
(20 + 12) - 8, since the question states n is EIGHT less than the sum of 20 and 12.
Answer:
A) No, because the greatest common factor is 8y?, and the completely factored form is 8y2(4y2 - 6y + 3).
Step-by-step explanation:
Considering the expression
4y(8y3 – 12y2 + 6y)
From the elements in the parenthesis, 2 and y can still be factored out such that what will be left of each element
8y3/2y = 4y2
12y2/2y = 6y
6y/2y = 3
Hence
4y(8y3 – 12y2 + 6y) = 4y*2y(4y2 - 6y +3)
= 8y2(4y2 - 6y + 3)
Yep! That's exactly what it means, 3 times whatever the value of x is.
Following the MDAS rule, where it is necessary to do multiplication or division processes first (whichever of the 2 is encounter first in the equation) before proceeding to addition and subtraction, the expression can be solved, and is done as follows:

Doing division and multiplication first:
30 - 18 + 24 - 20
Simplifying:
16
Therefore the answer among the choices is D.
