Answer:
X = 15
Step-by-step explanation:
We move all terms to the left:
<em>x+8+2x-(2x+13)=0</em>
We add all the numbers together, and all the variables:
<em>3x-(2x+13)+8=0</em>
We get rid of parentheses:
<em>3x-2x-13+8=0</em>
We add all the numbers together, and all the variables:
<em>x-5=0</em>
We move all terms containing x to the left, all other terms to the right:
<em>x=5</em>
The number 4.2 from the set will make the equation x+2=6.2 true.
Answer:
Step-by-step explanation:
V =
h
1. Find the radius.
8/2 = 4
2. Square the radius.
= 16
3. Multiply that by pi.
3.14 * 16 = 50.24
4. Multiply that by the height.
50.24 * 20 = 1004.8
5. Now find 60% of that.
1004.8 * 0.6 = 602.88
V = 602.88
Honestly, it's been a while since I've done this, but I believe this is the answer.
M + l = 13 [m = 13 - l]
8m + 10l = 108
8(13 - l) + 10l = 108
104 - 8l + 10l = 108
2l = 4
L = 2
M = 13 - 2 = 11
