Set up the equations:
2x+3y=80
1x + 4y = 100
solve for x and y:
1x + 4y = 100
x = 100-4y
plug into first equation
2(100-4y)+3y=80
200-8y+3y=80
y=120/5=24
x = 100-4y=100-96=4
So the charges are (x,y)=(4,24)
So the correct answer (B)
Expanded form means 3x3x3
As a power means 3 to the 3rd power (exponent of 3)
Value is 27 units cubed.
X=73 y=34
i think that is the answer
