Answer: 60 cm²
Step-by-step explanation:
This is pretty simple, we know AB is 12 cm and DE is 4 cm. We know ABC has a total of 180 square centimeters. So...
12 ÷ 3 = 4
180 ÷ 3 = 60
The answer is 60 cm²

1, 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47
So 16 integers.
Answer:
2.6
Step-by-step explanation:
3/5 ---> ?/100
100/5 ---> 20
3 20 60
-- x = -------
5 20 100
60/100 = 6/10
6/10 as a decimal is 0.6
2 + 0.6
= 2.6

Answer:
a) Add 4 to both sides, and then divide by 2. The solution is
.
Step-by-step explanation:
Question:
Which of the following describes the correct process for solving the equation 2x − 4 = 20 and arrives at the correct solution?
a) Add 4 to both sides, and then divide by 2. The solution is x = 12.
b) Divide both sides by −4, and then subtract 2. The solution is x = −7.
c) Subtract 4 from both sides, and then divide by 2. The solution is x = −12.
d) Multiply both sides by −4, and then divide by 2. The solution is x = −40.
Solution:
Given equation:
![2x-4=20](https://tex.z-dn.net/?f=2x-4%3D20)
We need to determine the steps in order to solve for
.
Solving for
.
Step 1: Adding 4 both sides.
![2x-4+4=20+4](https://tex.z-dn.net/?f=2x-4%2B4%3D20%2B4)
![2x=24](https://tex.z-dn.net/?f=2x%3D24)
Step 2: Dividing both sides by 2.
![\frac{2x}{2}=\frac{24}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B2x%7D%7B2%7D%3D%5Cfrac%7B24%7D%7B2%7D)
∴ ![x=12](https://tex.z-dn.net/?f=x%3D12)
Thus, we added 4 both sides and then divided both sides by 2 to get solution = 12
