Step-by-step explanation:
would include explanation but it would take a while hope it helped and may i have brainliest please?!
The formula for the circumference of a circle = 2 x radius x pi
The radius is given as 21 cm and pi = 3.142
Circumference = 2 x 21 x 3.142 = 131.964 cm
Answer:
C. 16
Step-by-step explanation:
First of all, these two angles are corresponding angles, which means that they equal each other. So, the equation here would be: 2x+18= 4x-14.
Step 1- Move the variables to one side.
2x+18= 4x-14
-2x -2x
18= 2x-14
Step 2- Add 14 to both sides of the equation.
18= 2x-14
+14 +14
32= 2x
Step 3- Divide 2 to both sides of the equation to isolate the variable.
<u>32</u>=<u> 2x</u>
2 2
x= 16
Hello!
To solve this equation, we need to isolate the variable on one side of the equation to see what it equals.
As you can see, 2.7 is added. To get it onto the other side and cancel it from the one side, you will subtract it from both sides as shown below. Note that because of the commutative property, we can switch the places of 2.7 and x.
x+2.7-2.7=17-2.7 (Note that 2.7=2.7 is 0 in this equation.
x=14.3
Our solution is x=14.3
I hope this helped you learn how to solve equations a bit better!
