= 2(Area of top) + 2 (area of side) + 2(area of front)
<span>= 2(28.5 x 24) + 2 (28.5 x 7) + 2 (24 x 7) </span>
<span>= 1368 + 399 + 336 </span>
<span>= 2103cm^2 </span>
3X+2Y=6
3X+1Y=5
Those are linear equations.
we can solve by elimination method.
3X+2Y=6
3X+1Y=5
⇒Y=1
∴X=4/3
Answer:
m = -4
Step-by-step explanation:
m - 4 = 2m
Switch sides.
2m = m - 4
Subtract m from both sides.
m = -4
Assuming this, you have to start by writing two equations from the information provided:
180 total tickets were sold
x+y=180
they made $590 and adult tickets cost $4 and kids tickets cost $2
180=4x+2y
lets solve for x in the first equation:
x=180-y
we can plug this into the second equation and solve for y
590=4(180-y)+2y
590=720-4y+2y
590=720-2y
-130=-2y
y=65
we can plug this into the first equation and solve for x:
x+65=180
x=115
I hope this helps.
