D because y (time spent) = 50 × x (distance travelled)
225÷4.5=50
x÷y=50
Answer:
10. 2x+y
11. x^2-15x+3
Step-by-step explanation:
10. when u add 7x+3y and 4x+4y you will get 11x+7y. 13x+8y minus 11x+7y will be 2x+y
11. when u add 3x^2+7x+1 and x^2-x+1 u will get 4x^2+6x+2. 5x^2-9x+5 minus 4x^2+6x+2 will be x^2-15x+3
