Answer 1

To determine how many months it will take for Donavan to weigh the same as Joshua, set up an equation and solve for x. It will take 5 months for Donavan to weigh the same as Joshua.

Step-by-step explanation:

To determine how many months it will take for Donavan to weigh the same as Joshua, we can set up an equation.

1. Let x represent the number of months.
2. Donavon's weight can be represented as 120 + 10x lbs.
3. Joshua's weight can be represented as 150 + 4x lbs.
4. We need to find the value of x when the weights are equal, so we set up the equation: 120 + 10x = 150 + 4x.
5. Solving the equation, we get 6x = 30, which simplifies to x = 5.

Therefore, it will take 5 months for Donavan to weigh the same as Joshua.
