Answer:
3)5x-4y=-3
6x+4y=14
Step-by-step explanation:
The system of equations is given
5x-4y=-3
3x+2y=7
Multiplying both sides of the lower equation by 2, we get
6x + 4y = 14
That means your answer 3)
5 is 120
and 6 is 650
and rounded idk what it is
but hope it helps
Answer:
40 degrees
Step-by-step explanation:
2x-30+x=90
Then you add x to 2x which will be 3x so now its
3x-30=90
add 30 to both sides
3x=120
divide 3 from both sides
x=40
Since Angle QPR is virticle to 2x-30+x=90
Angle QPR is 40 degrees
