Answer 1

Answer: (i) 3

(ii) 10

(iii) 1080

Explanation:

(i) Coefficient is the number written before any variable.

Coefficient of x in
`3x+10=36` is 3.

(ii) Constant is a numerical term written without any variable.

Constant in
`2x+10=5x` is 10.

(iii) Let x be the number of miles Katie's family drive.

Since they charge $30 combined with $0.25 per mile drive.

So, Total charge = 0.25 x +30 ( in dollars)

If they charged $300, then

`0.25 x +30 =300`

Subtract 30 from both sides, we get

`0.25x=270`

Divide both sides by 0.25, we get

`x=1080`

Hence, Katie drove 1080 miles.
