Step one: 200-87.96=112.04
Step two: 112.04÷30≈3.7
Step three: 3.7↔3
Answer: Staci can buy 3 shirts
Cos (B) = (a^2 + c^2 -b^2) / (2 * a * c)
cos (B) = (11^2 +17^2 -12^2) / (2 * 11 * 17)
cos (B) = (121 + 289 -144) / (374)
cos (B) = 266 / 374
cos (B) =

The answer is 2:3 because it is 12:18 simplified.
Answer:
8 arrangement
Step-by-step explanation:
2 white balloons and 3 red balloons for every arrangement
3x(4x - 15) < Given
12x^2 - 45x < Distributive law of property
By the way, you are simplifying not solving. You solve equations and simplify expressions.
