The answer is 32, depending on how you do the math will be different outcomes
Answer:
7 rows
Step-by-step explanation:
total 42 tiles. 6 columns mean, each column will have 6 tiles. so to have 42 tiles, 6*7 required
The standard equation of a circle:

(h, k) - center
r - radius
We have:
(2, -8) → h = 2, k = -8
r = 9
Substitute:

Answer:
Step-by-step explanation:
shirt = x, pants: y
Katie equation: 3x + 2y = 80, Erin equation: 3x + 4y = 116
3x + 2y = 80
3x = 80 - 2y
x = 80/3 - 2y/3
3(80/3 - 2y/3) + 4y = 116
80 - 2y + 4y = 116
80 + 2y + 116
2y = 36
y = 18, pants cost $18
3x + 4(18) = 116
3x + 72 = 116
3x = 44
x = 14.66... (66 is repeating), shirts cost $14.66
check work:
Katie: 3(14.66) + 2(18) = 79.98 which is roughly 80.
