Pi x 5squared = 78.5
10 x 10 = 100
100 - 78.5 = 21.5
Answer = A - Labor Day
X + y = 40
2x + 3y = 88
-2x -2y = -80
2x + 3y = 88
0 + y = 8
y= 8
x + y = 40
x + 8 = 40
x = 32
2x + 3y = 40
2(32) + 3(8) = 88
64 + 24 = 88
32 $2 tickets and 8 $3 tickets.
Ok so to solve to first one u do this:
62.4 - 31.53, which gives u 30.87. and then u add 30.87 and 31.33, and u get 62.4
for the second one u do the same thing.
Cross multiply.
5.4x=9*25.8
5.4x=232.2 Divide both sides by 5.4
x=43
