Hello from MrBillDoesMath!
Answer:
x = -11, y = 6
Discussion:
I don't understand the answer shown -- "Doesn't Exist" -- especially as part of the problem statement is not displayed, BUT
-6x + 3y = 84 => divide both sides by 3
-2x + y = 84/3= 28
-2x + y = 28 (A)
Multiply X = -23 + 2Y by 2 to get
2x = - 46 + 4y (B)
Adding (A) and (B) gives
(-2x + y ) + (2x) = 28 + (-46 + 4y) =>
y = 28 -46 + 4y => as -2x + 2x = 0
y = -18 + 4y =>
18 = 3y =>
y = 6
From (A) -2x + (6) = 28 or -2x = 28 -6 = 22 so x = -11
Thank you,

The total volume is the sum of volume of cone and volume of cylinder.
Volume of cylinder = πr²h
π = 3.14
r = 4/2 = 2 mm
h = 2 mm
So, volume of cylinder equals:
mm³
Volume of cone =
π = 3.14
r = 2 mm
h = 3 mm
So, volume of cylinder equals:
mm³
Thus, total volume of the figure = 25.12 + 18.84 = 43.96 mm³
Answer: $1090
Step-by-step explanation:
Since Caroline won $205000 in a lottery and then paid $96000 in taxes, the remaining amount will be:
= $205000 - $96000
= $109000
The interest that the account will earn after just 6 months will be:
Interest = PRT
= 109000 × 2% × 6/12
= 109000 × 0.02 × 0.5
= $1090
