Answer:
The number of students who were on each bus
Step-by-step explanation:
- Notice there are 70 students, and 70 is the sum of the equation
- We know 6 students weren't on either bus
- The remaining students must represented by 2b
- So if 2b is all the students who got on buses b is half that, representing each group of students per bus
Answer:
7.5
Step-by-step explanation:
15×12=180
180÷24(crayons per box)=7.5 boxes
In percent equation method , we transformed the number that we wanted to look for the percentage of into decimals and simply move the commas into two number on the right
If you get a hang on it, this method will be faster than the percent equation
hope this helps
Let a = weight of large box in pounds
Let b = weight of small box in pounds
(1) 65a + 70b=4000
(2) a+b=60
Now we can simultaneously solve these equations.
a = 60 - b. Hence 65(60 - b) + 70b = 4000 So 3900 + 5b = 4000 and 100 = 5b hence b = 20.
SImilarly a = 40. Now we can verify too by putting in the calculated values.
