D. 350.00
6. luke drove 120 miles in 3 hours. at this
rate, how long will it take him to drive 280
miles?
a. 9 hours
b. 7 hours
c. 5 hours
d. 4 hours

B. 7 hours

Step-by-step explanation:

Since the question states "at this rate" , this could be worked out by using simple proportion.

120miles = 3hours

280miles = ?

(280x3)/120 = 7 hours

no, the equation would be invalid since they are both not equal.

step-by-step explanation:

here you got

4y-6+4y 2-9

first, you would simplify the equation on the form.

4y-6+4y 2-9

then, move all the terms that contains a y to the left and all the other terms to the right.

+4y-4y+-9-6

finally, you will simplify the left and the right side of the equation.

y=-3
