Answer:
G = 1, 9.
Step-by-step explanation:
There are two cases to this problem: G is either to the left or right of E. If G is to the left of E, then G = 5 - 4 = 1 and if G is to the right of E, then G = 5 + 4 = 9. Therefore, our answer is G = 1, 9.

Answer:
125 %
Step-by-step explanation:
Computers purchased in the last month = 8
By the middle of the current month, 8 more computers than the last month were purchased. This means, total number of computers purchased by middle of current month = 8 + 8 = 16
Number of computers purchased by end of current month = 2
So,
Total computers purchased by current month = 16 + 2 = 18
We have to find the percentage increase in the number of computers from last month's purchases to the end of this month's purchases. The formula for percentage change is:

Here, Original Value is the number of computers from last month and New Value is the number of computers from current month. Using the values in the formula, we get:

Thus, there was a 125% increase from last month's purchases to the end of this month's purchases
Let the unknown number be x.
x × -7 = 7 (x + -40)
-7x = 7x - 280
-14x = -280
x = 280/14
x = 20
Hope this helps!
