Brooke's class took a field trip to the art museum. They left school at 11:04 A.M. It took them 1 hour and 19 minutes to drive to the museum. They stayed at the museum for 3 hours and 41 minutes. What time was it when Brooke's class left the museum?

Answers

Answer:

11.30am

Step-by-step explanation:

They time he left equal to the time he came

Let's calculate the time when Brooke's class left the museum. They spent 3 hours and 41 minutes at the museum, so if we add that to the time they arrived, we'll get the departure time.

They arrived at the museum 1 hour and 19 minutes after leaving school at 11:04 A.M. To calculate the arrival time, we add 1 hour and 19 minutes to 11:04 A.M.

11:04 A.M. + 1 hour and 19 minutes = 12:23 P.M.

Now, if we add the 3 hours and 41 minutes they spent at the museum to the arrival time of 12:23 P.M., we can find the departure time.

12:23 P.M. + 3 hours and 41 minutes = 4:04 P.M.

So, Brooke's class left the museum at 4:04 P.M.

What value of x is in the solution set of 9(2x + 1) < 9x – 18?

Answers

To solve these kinds of problems, it is necessary to isolate x:

9(2x + 1) < 9x - 18

Distribute 9:
18x + 9 < 9x - 18

Subtracting 9 from both sides of the equation:
18x + 9 - 9 < 9x - 18 - 9
18x < 9x - 27

Subtracting 9x from both sides of the equation:
18x - 9x < 9x - 27 - 9x
9x < -27

x < -3

Therefore, values of x < -3 will satisfy the given equation.

Answer:

x ∠ -3

Step-by-step explanation:

To solve this inequalities, we have to follow the steps below

open the bracket

collect like term

subtract and then divide both-side so that we can be left with just the variable

9(2x +1) < 9x - 18

opening the bracket, equation becomes;

18x + 9 < 9x - 18

collect like terms, numbers with x variables on the left hand side and number standing alone on the right hand side of the inequality

18x - 9x < -18-9

9x < -27

Divide both-side of the equation by 9

9x/9 < -27/9

Jane has a checkbook balance of $68.00. She then writes two checks, one for $5.00 and one for $62.50. She also deposits $75.00. She then uses her calculator to determine her new balance.

Answers

C because you want to do the steps in order. She started out with $68 then you subtract $5 and & 62.50 Then you add the deposit of $75.00

C because 5 and 62.50 is what she took at of her account. But she put in $75 somyou add that
