B is the answer to this question.
Answer:
x = 1/2 y = -5/2
Step-by-step explanation:
Since we already know an equation for y, we just need to plug it into the other equation.
21x - 7(-5x) = 28
21x + 35x = 28
56x = 28
x = 1/2
Now that we know x, we substitute it into the other equation, to find y.
y = -5x
y = -5(1/2)
= -5/2
That is the lowest unlest you want it in decimal form -0.390805
NOQ POQ is the answer because it adds up to 180 degrees
Answer:
a=1
Step-by-step explanation:
a+3=2a+2
Take away 3 from both sides
a=2a-1
Take away 2a from both sides
-a=-1
Multiply by -1
a=1
