Answer:

Ashley should have added 4.5 to both sides.

Step-by-step explanation:

Given expression:

-4.5+m=17

Ashley's solution:

Subtracted 4.5 to both sides and got,

m=12.5

Correct solution:

Adding 4.5 to both sides.

-4.5+m=17

 +4.5          +4.5

∴ m=21.5

Error made by Ashley was subtracting 4.5 both sides. Instead he should have added 4.5 both sides.

the large Square above has area 9 is divided into 9 smaller squares of equal area what is the length of how strong and bold
Kay [80]
If one square is divided into 9 smaller equal squares, then they have to be arranged in 3 lines of 3, that is 3 smaller equal squares per side of the original big square. That said, the area of the big square is equal to the multiplication of 3 small squares sides times 3 small squares sides, call x the length of the small squares.
So,
area = 9 = 3x*3x
9x^2 = 9
x^2 = 1
x = 1
therefore the smaller squares have sides of 1 unit

Let x represent the amount of lawn mowers that were manufactured

The company has to pay $34,816 before they even make any lawn mowers plus $388 per lawn mower.

((34816+388x)/x)=660
34816+388x=660x

X=128

Therefore, there were 128 lawn mowers manufactured
