4) I

Step-by-step explanation:

P = 2(l + w)

P = 2(3a + 3 + 8a - 12)

P = 2(11a - 9)

P = 22a - 18

P = 22(3) - 18

P = 66 - 18

P = 48

P = a + b + c

P = 3b + 7 + 7b - 2 + 7b - 2

P = 17b + 3

P = 17(6) + 3

P = 102 + 3

P = 105

Mr Smith is on a road trip from Cleveland to Chicago. He is 65% of the way there , and has already driven 455 miles. How many mo

Keith_Richards [23]

Hi i'd be glad to help you with this equation.

basically all we have to do is find (65%) of 455*.

65% of 455* = 295.75

Next.

455 + 295.75 = 750.75

So, to check my work I have 750.75 miles in total.

I have already driven 455 miles of 750.75 miles.

Using subtraction we subtract our distance from our total.

750.75 - 455 = 295.75

So, in total your answer to this problem is (295.75)

Hope this helps.
Have a great day!
