Answer:
if you ment to say 2 is 12.5% of what number the answer would be 16
Step-by-step explanation:
Write down what you know with x as the number you need to find.
Of is always "multiply"
Choose another way to write 12.5%
2 =12.5% of x
So 2 = 0.125xx
x= 2 *over*0.125
x=16
Yay! I'm so glad that this system of linear equations has to be solved by substitution because it is my favorite way to solve these kinds of problems. I will explain how to do this problem step by step, just like I learned in 8th grade. I hope this makes sense to you :)
Step 1: Solve for either x or y in one of the two equations.
-4x - 2y = -14
+ 4x + 4x
---------------------------
-2y = 4x - 14
------ ------ ------
-2 -2 -2
y = 2x + 7
Step 2: Plug in the solution you got for x or y into the equation you have not worked with yet. (2x + y = 7)
2x + 2x + 7 = 7 ⇒ 4x + 7 = 7
- 7 - 7
--------------------
4x = 0
----- -----
4 4
x = 0
Step 3: Plug in the solution you got in step 2 into either of the 2 equations.
2(0) + y = 7 ⇒ 0 + y = 7
- 0 - 0
----------------------
y = 7
The final solution to a systems of linear equations is written in a coordinate pair. (x,y)
In your case, the final answer would be (0, 7).
Volume of a cylinder is pi*r^2*h so we get
3.14*4.5^2*10=636.2cubic feet or ft^3

Answer:
B: Ella got a higher ratio on this week's test.
Step-by-step explanation:
Lets gather info:
13:15 and 16:20.
So, is
Ok. 13/15 is 0.87.
16/20 is 0.8
So Ella got a higher ratio on this weeks test.
So B.
Hope this helps plz hit the crown :D
