How many solutions are there to the equation 11x+25=7x+15

Answers

Just one 11x+25=7x+15 11x - 7x = 15 -25 4x = -10 x = -10/4 x = -5/2

There is only one solution for this equation which is x = -2.5 11x+25=7x+15 11x+25-7x=15 11x-7x=15-25 4x= -10 x = -10/4 x = -5/2 x = -2.5

travis has passed 11 tests and his classmate Jennifer has passed 2 tests. Going forward Travis plans to pass 2 tests per week. Meanwhile Jennifer plans to pass 5 tests per week. Eventually she will catch up to Travis. How many tests will each student have passed and how many weeks will it take?

Answers

If Travis already has passed 11, and Jennifer has already passed 2, then we just add 2 to Travis and 5 to Jennifer x amount of times until they have passed the same amount of tests. So:

Travis:    11 Jennifer: 2
Week1    + 2     + 5
Week2     2    5
Week3     2    5
      -------          --------
17    17

So= it will take 3 weeks for them to have both passed a total of 17 tests each.

Your video membership cost $14 per month for 10 video rentals. Each additional video rental is $2. Write in equation into variables that represent the cost of your video rentals.

Answers

Answer:the equation that represents the cost of your video rentals is y = 14 + 2(x - 10)

Step-by-step explanation:

Let x represent the number of video rentals that you made in a month.

Let y represent the total cost of x video rentals that you make in a month.

Your video membership cost $14 per month for 10 video rentals. Each additional video rental is $2. Therefore, the equation that represents the cost of your video rentals would be

y = 14 + 2(x - 10)

Where x - 10 is representing additional video rental above 10

Find two consecutive internet's whose sum is 75

Answers

37 and 38

consecutive integers have a difference of 1 between them

let n and n + 1 be the consecutive integers, then

n + n + 1 = 75 ( subtract 1 from both sides )

2n = 74 ( divide both sides by 2 )

n = $(74)/(2)$ = 37

the integers are 37 and 37 + 1 = 38
