Answer: x = 4; x = 5
Step-by-step explanation:
The directions specify to solve by factoring
x^2 - 9x + 20 = 0
To factor, find two numbers that add to -9 and multiply to 20
-5 and -4 work
-5 + (-4) = -9
-5 * -4 = 20
(x - 4)(x - 5) = 0
x = 4, x =5
Angles 6 and 8 add up to equal 180, so 2x - 5 + x + 5 = 180. 3x = 180 so x = 60. Angle 3 is alternate interior to angle 6 which is 2(60) - 5 = 115, so angle 3 is also 115
Answer
12
Step-by-step explanation
there is 15 of each color 3 take away 15 equals 12 red skittles left
2.5 + 3 = 5.5 total speed
7miles / 5.5 mph = 1.27 hours
First one because when you subtract 7 u keep the var. x alone and isolate it.
