To determine how many years it will take Cody to collect 577 coins, we can set up an equation.
Let's start with the number of coins Cody has initially, which is 22.
In each subsequent year, Cody plans to add 15 coins to his collection.
So, the number of coins Cody has after x years can be represented by the equation:
22 + 15x = 577
To solve for x, we need to isolate it on one side of the equation.
Subtracting 22 from both sides of the equation:
15x = 577 - 22
Simplifying:
15x = 555
Dividing both sides of the equation by 15:
x = 555 / 15
Simplifying:
x ≈ 37
So, it will take Cody approximately 37 years to collect 577 coins.
To find out how many years it will take Cody to collect 577 coins, we can set up an equation:
Cody's starting collection = 22 coins
Number of coins added each year = 15 coins
Total number of coins to be collected = 577 coins
Let's assume it takes Cody "x" years to collect the total number of coins.
The equation would be:
22 + 15x = 577
To solve for "x," we need to isolate it on one side of the equation. We can do this by subtracting 22 from both sides:
15x = 555
Then, divide both sides by 15:
x = 37
Therefore, it will take Cody 37 years to collect 577 coins.
Tom is given the equation 10x+15=20
to solve. He says the solution is 1/2
. Which reason justifies his solution?(1 point)
