Greatest Common Factor: 12-1/3 = -4/12, 7/4 = 21/12-4/12 + 21/12 = 17/12
Answer in simplest form: 17/12
Let the distance be D miles
Car A:- D = 2.4R and for Car B:- D = 4(R- 22)
therefore 2.4R = 4(R-22)
4R - 88 = 2.4R
1.6R = 88
R = 55mph Answer
Answer:
12
Step-by-step explanation:
Pythagorean Theorem states that
a² + b² = c²
plug in your terms
9² + b² = 15²
81 + b² = 225
then subtract 81 from 225 to get your b²
b² = 144
then find the square root of 144
the square root is 12 because 12 x 12 = 144
