Answer:15
Step-by-step explanation:you multiply m=5 to n=3 so what is 5 times 3? so 5 times 3 = 15
Answer:
-18x + 36 for the -6(3x-4) and 12x - 20 for the one on the image.
Step-by-step explanation:
You have 2 questions so I'll answer both of them (One written and the image as well)
-6 (3x-4)
You need to multiply -6 by 3x and -4
-18x + 36 Is the simplified version
**Remember that when multiplying two negatives they turn into a positive.
-2x (-6 + 10)
You need to multiply -2x by -6 and 10
12x - 20
I believe its C because that is slope intercept form and any points that follow that formula is a solution to that equation. And there is more than 1 solution to this equation.
30 min = 30/60 hr = 0.5 hr
d = rt
100 = r*0.5
100/0.5 = r
200 = r
r = 200 mph.
We know that Rate = distance/time
(30 minutes is .5 hour)
Rate=100 mile/.5 hour
Divide and we get:
Rate=200 MPH
(Hint: MPH is Miles per Hour---Per means "for each")
Make sense?
Answer: The least number of minutes that he has used his phone in a month is 1248
Step-by-step explanation:
Let m represent the number of minutes that he used his phone in a month.
For his phone service, Michael pays a monthly fee of $16, and he pays an additional $0.04 per minute if use. This means that if he used m minutes in a month, the total cost would be
16 + 0.04m
The least he has been charged in a month is $69.52. This means that
16 + 0.04m ≥ 65.92
0.04m ≥ 65.92 - 16
0.04m ≥ 49.92
m ≥ 49.92/0.04
m ≥ 1248 minutes
