A+b=82
2a+4b=324
Solve for a and b. a is the # of borogoves, b is the # of mome raths.
To solve number eight, you would set it up as an equation equal to 180
72+7x+24=180
Next you would combine like terms 24 and 72 to get 96
Now the equation is 96+7x=180 Now, subtract 96 from 180 and then divide by seven to get x, so then x is equal to 12
Answer:
x+y=-8
Step-by-step explanation:
y-x=4
x=3y
y-3y=4
x=3y
-2y=4
x=3y
y=4/(-2)
x=3y
y=-2
x=3*(-2)
x=-6, y=-2 then
x+y=-6-2=-8
Check the picture below.
if we know the endpoints of the circle, then its center must be the midpoint of those two endpoints.
