The two angles shown are supplementary angles, meaning that there sum equals 180. Knowing this you can set up an equation and solve for h...
3h + 18 + 15h = 180
Combine like terms
18h + 18 = 180
Subtract 18 to both sides
18h + (18 -18) = 180 - 18
18h = 162
Isolate h by dividing 18 to both sides
18h/18 = 162 /18
h = 9
Hope this helped!
I think the answer is (-2,-1).
Answer:
y=1.8
Step-by-step explanation:
first change the fraction into a decimal.
4/5 =0.8
plus the 0.8 to both sides
y=1.8
Answer:
This is true for all x
Step-by-step explanation:
-2(x + 3) = -2(x + 1) - 4
Distribute
-2x-6 = -2x-2 -4
Combine like terms
-2x-6 = -2x-6
Add 2x to each side
-2x+2x-6 = -2x+2x-6
-6 = -6
This is always true so there are infinite values
This is true for all x
