Devo'n ends up working twice as many hours at the senior center than with the school's custodial staff. If he worked a total of 45 hours, how many were spent with the custodial staff?

The equation is X + Y= 45

Sorry man, i cant help ya with that one

easy, just translate the English into math

let the number of hours with the custodial staff be x, then the number of hours with the seniors is 2x

so x + 2x = 45
x = 15

To solve this problem, we can set up a system of equations with two variables. Let's use X to represent the number of hours Devo'n worked with the school's custodial staff, and Y to represent the number of hours he worked at the senior center.

According to the problem, Devo'n worked twice as many hours at the senior center as he did with the custodial staff. This can be written as:

Y = 2X (Equation 1)

We also know that the total number of hours Devo'n worked is 45:

X + Y = 45 (Equation 2)

Now we have a system of two equations:

Y = 2X

X + Y = 45

To solve this system of equations, we can use substitution or elimination method.

Let's solve using substitution method:
Since Y = 2X, we can substitute 2X for Y in Equation 2:
X + 2X = 45
3X = 45
X = 15

Now that we have found X, we can substitute this value back into Equation 1 to find Y:
Y = 2(15)
Y = 30

Therefore, Devo'n spent 15 hours with the school's custodial staff.
