Answer:
I believe it is answer B if it's wrong I'm very sorry/
Step-by-step explanation:
If you plug in the x and y, you get
7(1)(3)
7 x 1 x 3 = 21, so the answer is 21
Answer: 3 hours
Step-by-step explanation:
If you add up 25+15=40 if you add up 40+15=55, 55+15=70, 70+15=85
Ok so basically solve for y
x-y=12
27+3y=2x
27+3y=2x
subtract 3y from both sides
27=2x-3y
2x-3y=27
x-y=12
multiply by -2
-2x+2y=-24
add them
2x-3y=27
<u>-2x+2y=-24 +</u>
0x-1y=3
-y=3
y=-3
y coordinate is -3
2.
y=2x+14
-4x-y=4
y=2x+14
subtract 2x from both sides
y-2x=14
mulitply both sides by -2
-2y+4x=-28
add the 2 equations
-2y+4x=-28
<u /><u>-y-4x=4 +</u>
-3y+0x=-24
-3y=-24
divide both sides by -3
y=8
y coordinate is 8
1. y coordinate is y=-3
2. y coordinate is y=8<u>
</u>
This first one is - M
second one is - GD
