Answer:
9
Step-by-step explanation:
Answer:
x=5, y=-2. (5, -2).
Step-by-step explanation:
2x+3y=4
3x+4y=7
----------------
3(2x+3y)=3(4)
-2(3x+4y)=-2(7)
----------------------
6x+9y=12
-6x-8y=-14
-----------------
y=-2
2x+3(-2)=4
2x-6=4
2x=4+6
2x=10
x=10/2
x=5
Answer: 62
Step-by-step explanation:
You do 112-19-31 and then it equal = 62
Answer:
A2 = 120
A3 = 60
A5 = 60
A6 = 120
Step-by-step explanation:
Angle 1 and 2 are supplementary, so A2 = 180 - 60, which is 120.
Angle 1 and 3 are vertical angles, which are always the same measure.
Angle 5 is alternate interior angles with 3, which means it is also 60.
Angle 6 is alternate interior angles with 4, which means it is 120.
