Question #9de6c

Answer 1

You need to represent the number of males in terms of females.

Explanation:

Since you know the number of males relative to females, it makes sense to represent the number of females as a variable, let's say `f`.

So then the number of males is `f + 240` and we know that the number of males plus the number of females is 2500. Knowing this, we can write an equation: `f + (f + 240) = 2500`. I put the number of males in brackets there just to make it easy to recognize.

This equation can be condensed into `2f + 240 = 2500` and then solved:

`2f = 2500 - 240`
`f = (2500 - 240)/2`
`f = 1130`

Then, we know the number of females, and we can solve for the number of males from here using our male formula: `ma\l\es = f + 240`. You should then get 1370 as the number of males.

Checking this answer, we see that 1130 + 1370 does equal 2500.

Answer 2

i got: `1370` males and `1130` females.

Explanation:

Call the number of males `m` and females `f`.

You get:

`m+f=2500`

and

`m=f+240`

substitute the second into the first:

`f+240+f=2500`

`2f=2500-240`

`f=2260/2=1130`

so that:

`m=1130+240=1370`
