<span>(100/x)*x=(60/18)*x </span>
<span>100=3.33333333333*x </span>(3.33333333333)
<span>100/3.33333333333=x </span>

Answer:
(-3,-1)
Step-by-step explanation:
-x+y=2
3x-5y=-4
in the top equation, we can get y by itself on one side of the equation:
-x+y=2
y=x+2
now, since we know that y=x+2, in the bottom equation we can substitute x+2 for y (substitution method) and solve:
3x-5y=-4
3x-5(x+2)=-4
3x-5x-10=-4
-2x-10=-4
-2x=6
x=-3
since we now know that x=-3, we can use it to find y by plugging in -3 for x in the top equation (you can do it in either equation, but doing it in the top equation is easier):
y=x+2
y=-3+2
y=-1
answer: (-3, -1)
Add 20 to complete the square
Answer:
222.86
Step-by-step explanation:
<h2><u>in order to solve this question you can create an equation :</u></h2>
35% * x = 78
where x is the original amount
in order to get x , you have to say :
78/ 35% = x
hence x = 222.8571...
to 2dp = 222.86
