The answer is 2x + y - 53/2
5 + 8s = 15 + 3s
8s - 3s = 15 - 5
5s = 10
s = 10/5
s = 2 <=== they will charge the same at 2 sq ft
Answer:
r= 0
r= 1
b= -3
x= -3
Step-by-step explanation:
4r-8r=0
-4r=0
r=0
-15=-8r-7r
-15= -15r
r=1
3b+7-1=-3
3b= -3-7+1
3b= -9
b= -9/3
b=-3
3x+1-6x=7
-3x= 7-1
-3x= 6
x= -6/3
x= -3
Answer:
The actual measure of ∠1 = 40°
Step-by-step explanation:
We are given: ∠1 = 2x+6 and ∠2 = 8x+4
and both angles are supplementary. we need to find the actual measure of ∠1
Supplementary angles: If the angles are supplementary their sum is equal to 180°
In our case ∠1 +∠2 = 180°
2x+6+8x+4=180
Solving the equation to find x, then we can find the actual measure of ∠1
![2x+6+8x+4=180\\10x+10=180\\10x=180-10\\10x=170\\x=170/10\\x=17](https://tex.z-dn.net/?f=2x%2B6%2B8x%2B4%3D180%5C%5C10x%2B10%3D180%5C%5C10x%3D180-10%5C%5C10x%3D170%5C%5Cx%3D170%2F10%5C%5Cx%3D17)
So, value of x = 17
Now, finding actual measure of ∠1 by putting x=17 in equation 2x+6
![\angle1=2(17)+6\\\angle1=34+6\\\angle1=40](https://tex.z-dn.net/?f=%5Cangle1%3D2%2817%29%2B6%5C%5C%5Cangle1%3D34%2B6%5C%5C%5Cangle1%3D40)
So, the actual measure of ∠1 = 40°
Answer:
$50.83
Step-by-step explanation:
44.20 x .15 = 6.63
44.20 + 6.63= 50.83
