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.
