Answer:
Step-by-step explanation:
4x+2y = -24 -------------(i)
<u> -4x+y = 12 -</u>------------(ii)
add (i) &(ii) 3y = -12
y = -12/3
y = -4
Put y = (-4) in (i)
4x + 2*(-4) = -24
4x - 8 = -24
4x = -24 + 8
4x = -16
x = -16/4
x = -4

Answer:
$10.64
Step-by-step explanation:
We know that 1 pound, costs $4.25, so to begin I added that together. And gave myself 8.50. Now, we know that we have 2 pounds. We need 2.5 so, I devided 425 by 2, and got 213.5. Now I know I have to round to the nearest cent. And 213.5 would round to 214. Now we put the decimal back in place and add our 2.14 to our 8.50 and get $10.64
