Answer: (i) 3
(ii) 10
(iii) 1080
Explanation:
(i) Coefficient is the number written before any variable.
Coefficient of x in
is 3.
(ii) Constant is a numerical term written without any variable.
Constant in
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
Subtract 30 from both sides, we get
Divide both sides by 0.25, we get
Hence, Katie drove 1080 miles.
