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
It will be 93 because it 92 but you have to round up with deimal number
Answer:
One avocado costs $1 and one tomato costs $0.50
Step-by-step explanation:
Set up a system of equations where t is the number of tomatoes and a is the number of avocados:
4t + 8a = 10
6t + 14a = 17
Solve by elimination by multiplying the top equation by 3 and the bottom equation by -2:
12t + 24a = 30
-12t - 28a = -34
Add them together and solve for a:
-4a = -4
a = 1
Plug in 1 as a into one of the equations and solve for t:
4t + 8a = 10
4t + 8(1) = 10
4t + 8 = 10
4t = 2
t = 0.5
So, one avocado costs $1 and one tomato costs $0.50
