Answer:
you currently have the value of x × 7, you need to divide it by 7 to find the value of x.
42 ÷ 7 = 6
Step-by-step explanation:
Answer:
Distribute the -7 to both the x and the -12
Step-by-step explanation:
The first step taken would be to distribute the -7 to the x and the -12 to get rid of the ()
-7(x-12) = 42*
\/
-7x + 84 = 42*
Answer: x=-28
Step-by-step explanation:
Quotient of a number (say x ) and 4 = x/4
nine more than x/4 = 9 + (x/4)
9 +x/4 = 2
If you want a shorter way to find the perimeter then just multiply how many sides and the length of the side.
4 x4 = 16
However this only works if the 2D shape is an equilateral. So this trick only works in certain situations.
