Answer:
c) 500
Step-by-step explanation:
3% = 0.03
multiply the decimal from of 3% by 500:
500 x 0.03
solve:
500 x 0.03 = 15
First eliminate a single variable from all equations
wait, if we divide the last equation by 2, we can eliminate x and y in first equation
divide last equation by 2
then times -1 to get
-x-y=-2
add to first equation to get
-z=-1
z=1
sub back
x+y-1=1
x+2(1)=0
x+y=2
now we gots
x+y=2
x=-2
solve
-2+y=2
y=4
x=-2
y=4
z=1
Answer:
The answer is B
Step-by-step explanation:
It becomes 8y = -3x + 12.
Then divide by 8 on both sides.
y = -0.375+1.5
This you can turn it into a fraction which is y = -3/8 + 1.5
