Dylan makes $10.50 an hour
Angela makes $10.00 an hour
I got this by dividing 336 by 32 that got me answer 10.50
I divided $420 by 42 that got me $10.00
Here it is…
Simplifying
C = 25h + 50
Reorder the terms:
C = 50 + 25h
Solving
C = 50 + 25h
Solving for variable 'C'.
Move all terms containing C to the left, all other terms to the right.
Simplifying
C = 50 + 25h
Answer:
4/13 hours
Step-by-step explanation:
Total pounds of lasagna = 4 1/3 pounds
Total time taken to cook = 1 1/3 hours
How many hours per pound did it take to cook the lasagna?
Hours per pound of lasagna = Total time taken to cook / Total pounds of lasagna
= 1 1/3 hours ÷ 4 1/3 pounds
= 4/3 ÷ 13/3
= 4/3 × 3/13
= 4/13 hours
It will take 4/13 hours to cook each pound of the lasagna
Let x represent the number of boys.
Then 1/2x + 10 represents the number of girls. (there are 10 more than half the number of boys)
We can set up a simple equation for this situation:
# of boys + # of girls = 25 students
so
x + (1/2x + 10) = 25
x + 1/2x + 10 = 25
1/2 = 0.5
x + 0.5x + 10 = 25
1.5x + 10 = 25
1.5x = 25 - 10
1.5x = 15
x = 15/1.5
x = 10
x = # of boys, so there are 10 boys in the class.
Good luck on your math!
