Answer:
y=-1/2x+24
Step-by-step explanation:
you solve for y by isolating the y on one side of the equation and the rest of the equation on the opposite side of the equal sign.
1/2x-1/2x+y=24-1/2x
y=24-1/2x
rewritten: y=-1/2x+24
Answer:
60°
Step-by-step explanation:
180 - 115 = 65
180 = 65 + (9x + 6) + (9x + 1)
Subtract/simplify:
115 = 18x + 7
Subtract:
108 = 18x
Divide:
108/18 = 6
x = 6
Plug x back in:
9(6) + 6 = 54 + 6 = 60°
The answer for the problems are below in the picture let me know if that makes sense.

or you can turn it like this...
Answer:
a^2 +a -6
Step-by-step explanation:
(a + 3)(a - 2)
FOIL
first: a*a = a^2
outer: -2*a = -2a
inner: 3*a =3a
Last : -2*3 = -6
Add them together
a^2 -2a+3a -6
Combine like terms
a^2 +a -6
