Answer:
- <em><u>Given </u></em><em><u>,</u></em>
student's age = x years.
- <em><u>Also </u></em><em><u>,</u></em>
Teacher's age = 2x + 6
- <em><u>And </u></em><em><u>,</u></em>
Principal's age = 3x + 10
------------------------------------------
Difference between ages ,
therefore ,
second option is the correct answer.

To find their average miles per hour we can divide the total miles by the hour used:
4 2/3 ÷ 1 2/3
=4x3+2/3 ÷ 1x3+2/3
=14/3 ÷ 5/3
In division, when we switch the place of numerator and denominator, we can change it to multiplication which makes the calculation easier as we can factorize the numbers.
=14/3 x 3/5
Factorize 3 in both amounts:
=14/1 x 5/1
=14/5
=2.8 miles/hour
Therefore their average speed is 2.8 miles/hour.
Hope it helps!
Answer: The system of equations are
30x + 15y = 330
x = y + 2
Step-by-step explanation:
Let x represent the number of hours that Caleb worked.
Let y represent the number of hours that Landon worked.
Caleb can iron 30 shirts per hour, and Landon can iron 15 shirts per hour. This means that the number of shirts that Caleb would iron in x hours is 30x and the number of shirts that Landon would iron in y hours is 15y. They ironed 330 shirts between them. This means that
30x + 15y = 330 - - -- - - - - - - - - - - -1
Caleb worked 2 more hours than Landon. This means that
x = y + 2 - - - -- - - - - - - -2
Answer:
Lets say you have "100" apples.
If you lost 50% of those 100 apples, (50 apples) and then half of them went rotten, then no, it wouldn't be the same. But if you picked them all back up, and none of them were damaged, then yes, they would stay the original amount.
