The formula of a cirumference of a circle:
r - radius
We have r = 10. Substitute:
<h3>Answer: C = 20π</h3>
Answer:
<u>Yes</u>
Step-by-step explanation:
<u>When there are 2 rows</u>
- Number of erasers per row = No. of erasers / No. of rows
- Number of erasers per row = 18/2
- Number of erasers per row = 9
<u>When there are 3 rows</u>
- Number of erasers per row = No. of erasers / No. of rows
- Number of erasers per row = 18/3
- Number of erasers per row = 6
<u>Therefore, there will be more erasers per row in 2 equal rows than in 3 equal rows.</u>
Answer:
8x + 3
Step-by-step explanation:
In the expression -3x + 14 - 11 + 11x, we have two pairs of like terms that can be combined together:
-3x, 11x
14, -11
If we rewrite this expression with the like terms together, it would look like this:
-3x+11x + 14-11
To make the addition of -3x and 11x easier, we could switch their places in the expression to make it look like this:
11x-3x + 14-11
(Note: Even though we are switching the terms' places, the -3x still keeps its negative sign when you move it around.
11x-3x is 8x and 14-11 is 3.
Therefore, the expression -3x + 14 - 11 + 11x can be simplified by combining like terms into 8x + 3.
Add 4 to both sides to isolate the variable (-4+4=0) (2x+0=2x) (0+4=4) which leaves you with 2x=4 divide both sides by 2 to get rid of the number in front of the variable to get x by itself (2x/2=x) (4/2=2) therefore you’re left with x=2 (lo siento yo no hablo español la respuesta es x=2)
