Question

Susan spends four hours a day,Sunday through Friday,surfing the internet.During the entire week,she spends an average of 5 hours per day surfing.On Saturday,how many hours does she spend on the internet?

Answer 1

Could someone help me

Answer 2

[(6)(4) + x] / 7 = 5 where x is the # of hours on Saturday.

So, multiply both sides by 7 and then subtract 24 from both sides to get "x".

Answer 3

Its a bit hard for me to understand

Answer 4

I'll rewrite it using the equation tool so it's easier to see.

Answer 5

Thank you

Answer 6

\[\frac{ (6 \times 4) + x }{ 7 } = 5\]The "6" is from six days (not including Saturday). "x" is Saturday hours. When you add them all together for (6 x 4) + x you get the total # of hours of internet surfing for the week and now you divide by 7 to get the average per day, which we know to be 5 because we were given that information.

Answer 7

When you multiply both sides by 7 you get:

(6 x 4) + x = 5 x 7 = 35

"x" can be solved from this as it becomes:

24 + x = 35

Subtract 24 from each side:

x = 11

Answer 8

So the answer is 11

Answer 9

Yes. x = 11.
