Because they are same-side interior they are supplementary:

5x + 15 + 3x - 3 = 180
8x + 12 = 180
x = 21

5x + 15 = a
5(21) + 15 = a
120 = a

Hope this helps!

X=21 angle 1 equals 120

to find x you make am equation of 5x+15+3x-3=180 8x+12=180 x=21. then plug in 21 for x 5(21)+15 gives you the angle of 1 because Angel 1 and (5x+15) are corresponding angels in which they well have the same measurement

0.10c + 0.12b = 2.18
c = 4b + 1

0.10(4b + 1) + 0.12b = 2.18
0.40b + 0.10 + 0.12b = 2.18
0.40b + 0.12b = 2.18 - 0.10
0.52b = 2.08
b = 2.08 / 0.52
b = 4 <==== she had 4 bottles

c = 4b + 1
c = 4(4) + 1
c = 16 + 1
c = 17 <=== she had 17 cans

If the average of three numbers is V if one number is Z and another is y what is the remaining number ?
user100 [1]
The formula for an average of three numbers is (x+y+z)/3.  So if V equals the average, then we find the formula
V = (x+y+z)/3
We are now looking for x.  We can divide each of the variables in the parentheses by 3, making the formula
V = x/3 + y/3 + z/3
So now bring the unwanted variables to the same side as V.
V - y/3 - z/3 = x/3
Now multiply both sides by 3 to find x.
3V - y - z = x

x = 3V - y - z
