Step-by-step explanation:
equation: m-3n=16
Solution,
or, m - 3n = 16
or, m - 3×8 = 16
or, m - 24 = 16
or, m = 16 + 24
or, m = 40
Therefore, the value of m is '40'
Answer:
3.6
Step-by-step explanation:
Answer: x=-2
Y= -20
Step-by-step explanation
You replace the y in the second equation with 10x. This is because it says 10x=y
2x+10x=12x so you put that
12x=-24
To get x by its self you divide by 12.
-24 divided by 12 is -2.
Now you plug in -2 to either equation as y. I chose the first one because it's easier.
10(-2)=y
-20=y
Answer:
<h2>x = 114</h2>
Step-by-step explanation:
0.2x – 1.8/5 = 4.2
0.2x - 1.8 = 4.2 (5)
x =<u> 21 + 1.8 </u>
0.2
x = 22.8 / 0.2
x = 114
B because to be perpendicular the slope had to be opposite of the original slope but the same b. But parallel would be the exact same slope with a different b
