Answer:
The new cost is $20.30
Step-by-step explanation:
In order to find that, start by taking the original price and multiplying it by what percentage you have to pay. Since it is 30% off, you have to pay 70%
$29*70% = $20.30
280,000 would be the correct amount
Answer:
The answer is choices A.
Step-by-step explanation:
2 1/2+ 4 1/4 = 6 3/4
6 3/4+3 3/4= 10 1/2
6 4/9, hope this helps tell me if you need and explanation
8x + 3y = 20.50
-
4x+5y=22.50
=
4x-2y=-2, so you have to divide each number by 2, then
2x-y=-1, so
-y=-1-2x /-1, y=1+2x, then replace it with one original equation like the first one for instance:
8x+3(1+2x)=20.50, then
8x+3+6x=20.50, then
14x=20.50-3
14x=17.5
x=1.25, then solve y:\
y=1+2*(1.25)
y=1+2.5
y=3.5,
So answer is x=1.25, and y=3.5
