Answer:
Equation: y = -0.5x + 9.5.
Answer: 145
Step-by-step explanation:
you have to find what x is based on the other side
4x+15+30x-5=180
x=5
plug in 5 in 20x+45
which equals 145
In scientific notation, it would be:
A)3.3*10^2
Answer:
The first equation should be multiplied by - 7 and the second equation by 3
Step-by-step explanation:
Indeed, let s multiply the first equation by -7
-7*9x-7*3y=7*18
and the second one by 3
3*8x+3*7y=3*10
when we add both the terms in y will be -7*3y+3*7y= 0
and then we can solve on x
hope this helps
