Yes, 3 years is 36 months
12x3=36
Graph the two points and you'll see that the radius is 3.
C=2(pi)r
C = 2(3.14)(3)
C = 18.84
18-12+7
6 + 7
13
Write an equation.
Subtract first- the customer buys 12 black neon tetra fish which means subtraction
addition- the store clerk puts in 7 more black neon tetra fish which means your gonna add 7
Easy!
Since the greatest multiple of 9 lesser than 79 is 72, you get a remainder of 7
8 7/9
2y+4=3(y-1)
2y+4=3y-3
4+3=3y-2y
Y=7
X=2
