She multiplied it by 5, because that would make the equation:
2.5 + y = 125
So when we add -y and y cancel out
Answer:
-12 and -11
Step-by-step explanation:
Just be smart, all you gotta do is divide the -23 by 2
Answer:
When solving absolute value equations, such as [the absolute value of 2x + 5] = 13, it is important to create two equations.
2x + 5 = 13 and 2x + 5 = -13.
Resulting in x = 4 or -9.
.....
d = 4
d = -5
Answer: 16 + 55 = 71cm^2
Step-by-step explanation:
You want to divide this figure into 2 rectangles. There are two ways to do this, but either one will give you the same answer.
First One:
It has the dimensions of 5 and 11. 5 x 11 = 55cm^2
Second One:
This one wont be straightforward like the first one. You need to find these sides manually.
7 + x = 11
x = 4
Then,
9 - x = 5
x = 4
4 x 4 = 16cm^2
If you want area it’s 16 if you wanted perimeter it’s 20 if your asking for the number of the width it’s 8
