Answer:
2 5/7
Step-by-step explanation:
In order to solve this problem you must multiply the weight of the original puppy by the 1 2/7 times the second puppy weighs, giving you 2 5/7.
The best way to do this is to turn the mixed numbers into improper fraction, then, multiply straight across and simplify.
Answer:
40 mph.
Step-by-step explanation:
Suppose grandma's house is 30 miles away (any distance would do but 30 is convenient).
Speed = distance / time
time = distance / speed
Time to get there = 30/60 = 1/2 hour.
Time to get back = 30/30 = 1 hour
Average speed = total distance/ total time
= (30 + 30) / ( 1 + 1/2)
= 60 / 1.5
= 40 miles per hour.
You cannot take the average of the speeds directly
(60+ 30)/2 = 45 is not correct as you cannot average ratios ( speed is a ratio).
Step-by-step explanation:
Vertical line => Slope is Undefined.
12h + 44 = 15h + 35
h= number of hours that Val and Tony work
It is true that 3=4 times 3\4 because 4 times 3 equals 12 while 12 divided by 4 equals 3.
3=3 is true.
