Last​ night, 5 friends went out to dinner at a restaurant. They split the bill evenly. Each friend paid ​$11.50. If B represents the total bill in​ dollars, what equation could you use to find the value of​ B?

B=11.5x5

Step-by-step explanation:

5 people pay $11.50 to get a total of B.

To get the total bill, 11.5x5=57.5

B=57.5

The total cost of the bill is $57.50.

add all the numbers and check the ones place.

the answer is 486. as the ones place is more than 4, the estimation will be the next 10 ie, 490

5x+40

5(x + 8)

7x - 49

7(x - 7)

18x + 9

9(2x + 1)

15x - 10

5(3x - 2)

step-by-step explanation:

for number one all you have to do is factor 5 out of 5x + 40

for number 2 factor 7 out of 7x - 49

for number three factor 9 out of 18x + 9

for number four factor 5 out of 15x - 10
