Answer:
x = 3, y = -2
Step-by-step explanation:
Solving the bottom equation for y, we have y = 4 - 2x. Substitute that into the top equation, and solve for x.
4x - 3(4 -2x) = 18
4x - 12 + 6x = 18
10x - 12 = 18
10x = 30
x = 3
From this, we have y = 4 - 2(3) = 4 - 6 = -2
Answer:
-2
-2
y=-2

20:15 which reduces to 4:3 or 4/3 or 4 to 3 , hope that helped have a good day
Answer:
40
Step-by-step explanation:
angles QPR and RPS are complimentary, so they equal 90, or angle QPS, so you can set up the equations like so:
7x - 9 + 4x + 22 = 90
Combine like terms:
11x + 13 = 90
Subtract 13 from each side:
11x = 77
Divide each side by 11:
x=7
Then use this value in the angle that you are finding:
7(7) - 9
49 - 9
40
40 is your answer
Hope this helps!
The answer will be 12.4 if you really look at it you can multiply 3 by 2 get 4 add 12 and a decimal
