If you would like to solve the equation 16 = (- 5 + z) / 4, you can do this using the following steps:
16 = (- 5 + z) / 4 /*4
16 * 4 = - 5 + z
16 * 4 + 5 = z
z = 69
The correct result would be a. 69.
Answer:
x = -4
Step-by-step explanation:
(x - 4) = 2x
We need an x that when is subtracted by 4 is equal to multiplying it by 2
((-4) - 4) = 2(-4)
(-8) = (-8)
Therefore x = -4
PEMDAS
When solving an equation we do them in reverse order

Basically we are trying to get the variable alone.
12=10-3x
subtract 10 from each side
then divide by -3 on each side
3/5 x -12 = 18
first add 12 to each side
then multiply by 5/3 to each side
Start by finding the area of one of the stools with this formula:
A=(3.14)(12)(12)
Then multiply that answer by five, since there are 5 stools.
Hope this helps :) good luck
Answer:
44u-36
Step-by-step explanation:
Apply the distributive property.
−6(−7u)−6⋅6+2u
Multiply −7 by −6.
42u−6⋅6+2u
Multiply −6 by 6.
42u−36+2u
Add 42u and 2u.
44u-36
