20 mitiplay by 18 thats the answer
Answer:
Step-by-step explanation:
The system of equations is expressed as
-x -3y =18 - - - - - - - - - - - - - -1
x + 2y = -14 - - - - - - - - - - - - - -2
We would eliminate x by adding equation 1 to equation 2. It becomes
- y = 4
Dividing the left hand side of the equation and the right hand side of the equation by - 1, it becomes
- y/ - 1 = 4/ - 1
y = - 4
Substituting y = - 4 into equation 1, it becomes
-x -3 × - 4 =18
- x + 12 = 18
Subtracting 12 from the left hand side of the equation and the right hand side of the equation, it becomes
- x + 12 - 12 = 18 - 12
- x = 6
x = - 6
Answer:
y = 88
Step-by-step explanation:
Don't worry about the other stuff, just worry about what's in the triangle that has Y.
53°, 39°, and y°
the sum should be equal to 180 so add 53 adn 39 and subtract it from 180.
180 - (53 + 39) = y
180 - 92 = y
88 = y
Hope this helped! Pls Brainliest my answer! It would help amd mean a lot! ;)
