Answer:
x=4200, y=2700
Step-by-step explanation:
let x be first account
y the second
x+y=6900
0.03x+0.08y=342
solve by addition/elimination)
multiply first equation by 0.03
0.03x+0.03y=207 subtract from second
0.03x+0.03y-0.03x-0.08y=207-342
0.05y=135
y=2700, x=4200
Answer:
6075π ft^3
Step-by-step explanation:
The formula for a cylinder is πr^2 * h
were:
h = height
and r = radius
and because the radius is always 1/2 of the diameter, the radius is 22.5.
So now we plug everything in:
π*22.5^2 * 12
= π*506.25 * 12 =
π * 6075 =
6075π
please don't forget to add the units.
Answer:
2nd option
Step-by-step explanation:
Given
2x - 8y + 3x² + 7y - 12x ← collect like terms
= 3x² + (2x - 12x) + (- 8y + 7y)
= 3x² + (- 10x) + (- y)
= 3x² - 10x - y
Answer:
3
