Answer:
<h2>Jimmy is 16 old.</h2>
Step-by-step explanation:
J - the age of Jimmy John
50 - the age of Papa John
3J + 2 - the age of Papa John
The euaqtion:
3J + 2 = 50 <em>subtract 2 from both sides</em>
3J + 2 - 2 = 50 - 2
3J = 48 <em>divide both sides by 3</em>
3J/3 = 48/3
J = 16

Answer:
348 out of 725
Step-by-step explanation:
This is a ratio question, giving us a sample that we can use to extend the number to all students.
12/25 students play a sport so we want the value of x in x/725
So:
12/25 = x/725
Cross-Multiply:
25x = 8700
Divide by 25 to get x:
348
You can also check by dividing these ratios to see if you get the same number. In this case, you do (.48).
Elena's total cost (C) is 5(9.98 + 24.99 + x)
Since each dog leashes cost $9.98, each bag of dog food cost $24.99 and each crate of egg cost $x, hence:
Total cost (C) = 5 * $9.98 + (5 * 24.99) + (5 * x)
C = 5(9.98 + 24.99 + x)
Therefore Elena's total cost (C) is 5(9.98 + 24.99 + x)
