Yesterday, Linda went on a bike ride. Her average speed was 8 miles per hour. Today, she went on another ride, this time averaging 14 miles per hour. In the two days, she biked for a combined total time of 11 hours.
Let be the number of hours she biked yesterday. Write an expression for the combined total number of miles she biked in the two days.

below

Step-by-step explanation:

x be the miles for first day

y be the miles for 2nd day

8 miles in 1 hr

so x miles will be x/8

14 miles In 1 hr

so y miles will be y/14

x/8 + y/14 = 11

a) 0.25x times 3. (could be wrong on equation.)

b) 2.25 pound of dark chocolate. (can i eat all the chocolate? plz? anyway, again, could be wrong, but i hope im right. all the chocolate together should be 5.25 pounds)

have a good day!

fa tha first one you gonna add y to both sides

it look like this

x-y+y=6+y

x=y+6

therefore your answer is

x =y+6

fa tha second one

you gonna flip tha equation

it gonna look like x-4y=y

then add 4 to both sides

it gonna look like tha

x-4 +4 =y +4

so therefore tha answer is x=y+4
