If she can ride her bike 3 miles in 24 minutes how far can she ride her bike in 72minutes. So, if we find out how many times 24 goes into 72 (by dividing it) then times the answer by 3 because that’s how many miles she can do in 24 min. That will give you the answer e.g
Sally can ride her bike 4 miles in 12 minutes so how far can she ride her bike in 24 minutes. You do:
_2_. 2x 4 = 8 so she would be able to
12) 24. Do 8 miles I. 24 minutes.
Answer:
For the given expression: 
Step-by-step explanation:
Here, the given expression in statement form is given as:
5 X minus Y equals 6 + negative 2 X plus Y = 8
Now, converting the given statement mathematically, we get:
5X - Y = 6 + (-2X) + Y = 8
Now, considering first and the last terms,we get:
5 X - Y = 8 .... (1)
and , considering second and the last terms,we get:
6 + (-2X) + Y = 8 or, -2X + Y = 2 ......... (2)
Adding (1) and (2) , we get:
5 X - Y - 2 X + Y = 8 + 2
or, 3 X = 10
or, X = 10/3 = 3.34
Now, 5X - Y = 8
or, 
Hence, for the given expression:

Answer:
Rate is 9 kilometers (km)/week.
Step-by-step explanation:
9000 meters is 9 km (divide m by 1000 to get km)
For the first 6 1/3
