Answer:
25 and 30
Step-by-step explanation:
Let the smaller consecutive multiples of 5 be x. Therefore, other consecutive multiples will be x + 5.
Now as per statement the sum of two consecutive multiples of 5 is 55. To find the multiples. Thus
x + x + 5 = 55
2x + 5 = 55
2x = 55 - 5
2x = 50
x = 50/2
x = 25
This the smaller consecutive multiples of 5 is 25, the other consecutuve multiple is x+ 5, 25 + 5 = 30.
The consecutive multiple numbers of 5 are 25 and 30
Answer the two consecutive multiples of 5 are 25 and 30
Answer:
Jose traveled 52.5 miles in 1 hour
Step-by-step explanation:
What we're actually doing here is finding the "unit rate": the speed in mph:
35 mi 105 mi
------------ = ------------ = 52.5 mph = 52.5 miles in 1 hour
2/3 hr 2 hr
Jose traveled 52.5 miles in 1 hour
Wouldn't it just be 378-223? resulting with r=155?
Answer:
4 trips
Step-by-step explanation:
First, let's put all data in minutes.
One trip to granny's home takes 35m to go plus 35m to come back, plans 4m for waking from the parking to the apartment and some other 4m for going to get the car to come home. So the total time spent on one trip is:
35+35+4+4=78 minutes
The total time he counted was 5h12m. If we put this in minutes we need tu multiply the hours by 60 (as every hour has 60 minutes) and sum the 12 minutes:
5*60 + 12 = 300+12=312 minutes total.
If 312 is total time and 78 is the time for one trip, the ratio gives the amount of trips:
312/78=4
So, he made 4 trips, all of them took 78 minutes (you can verify it by summing 78 4 times).
