Step-by-step explanation:
You can check the solutions of the equations by putting the values of x, y, and z one by one.
Answer: 26
Step-by-step explanation:
divide 19.5 by 3/4 (0.75)
47/8 is an improper fraction so we need to divide 47 by 8 to get an mixed number.
8 go into 47, 5 times because 5*8 equals 40.
47-40 is 7 that is the left over.
5 7/8 is your mixed number.
Answer:
(x - 2) (x - 6)
Step-by-step explanation:
Factor the following:
x^2 - 8 x + 12
The factors of 12 that sum to -8 are -2 and -6. So, x^2 - 8 x + 12 = (x - 2) (x - 6):
Answer: (x - 2) (x - 6)
Rate = (150 miles)/(3 hrs) = 50 mph
so . . .
(50 mph)*(time) = 400 miles
*divide both sides by 50 mph
time = (400 miles)/(50 mph) = 8 hrs
time = 8 hrs
