I think you just draw a line from 9 to 4, i'm not so sure tho.
Step-by-step explanation:
*Snarls at my own stupidity*
2/8x - 4 = -10
+ 4 + 4
(8/2)2/8x = -6 (8/2)
x = -48/2
x = -24
Step-by-step explanation:
General formula for the area of a circle = πr^2.
Since the diameter is 8, the radius is 4 (half of diameter)
So the area is π(4)^2 = 16π.
Answer:
Josie bought 40 adult tickets and 32 children tickets.
Step-by-step explanation:
x+y=72
22x+10y=1200
-----------------------
x=72-y
22(72-y)+10y=1200
1584-22y+10y=1200
1584-12y=1200
12y=1584-1200
12y=384
y=384/12=32
x+32=72
x=72-32=40
x=40, y=32. (40, 32)
