These two have different denominators, so you find the least common multiple. This problem goes to be 2/8+5/8, which equals 7/8。
X-4y=-12
4x-y=12
eliminate y's
multily 2nd equaiton by -4 and add to top one
x-4y=-12
<u>-16x+4y=-48 +
</u>-15x+0y=-60
-15x=-60
divide both sides by -15
x=4
sub back
x-4y=-12
4-4y=-12
minus 4 both sides
-4y=-16
divide both sides by -4
y=4
x=4
y=4
(x,y)
(4,4)<u>
</u>
Answer:
Coordinate D. Because D lies on the 2nd quadrant, meaning that x has a negative value whereas y is positive.
If you want me to solve for "Y" then, the answer will be,
ir if you want me to solve for "X" instead then the answer will be,
Answer:
80%
Step-by-step explanation:
To find percent decrease (new amount/original amount)*100
(500/625)*100
=80
--
to check
625*.80
=500
or
625*80%
=500
