There were 450 students enrolled in a middle school at the beginning of the school year. The number of students enrolled in the school at the end of the year was 10 percent greater than the number of students enrolled in the school at the beginning of the year. How many students were enrolled in the school at the end of the year?

Answers

Answer:

495 students

Step-by-step explanation:

find 10% of 450:

450 x 0.1 = 45

45 students added through the year

now add 45 to the original 450 students

450 + 45 = 495

HELP!!!! Please?! Solve the equation below, and check the solution. -6x+7=79 the solution set is? BRAINLIEST ANSWER

Answers

Alright so, in order to solve an equation, you must have the unknown by itself.

So, we first subtract 7 from both sides and get a new equation.

-6x = 72

Now we divide by -6 so that x is by itself.

x = -12.

Now, -12 is a *possible* solution to the equation. The way to find out is to check. Checking the answer means "plugging in" the number into the equation, and seeing if it solves. so.

-6 * -12 + 7 = 79

72 + 7 = 79

79 = 79

So, since the answer checked out, -12 is a solution to the equation.

Hope this helps.

number 1 is a unit rate

a bottle of soda had 4 and 2/7 of the daily re commended sugar. if you were to drink 1/2 of the bottle. how much of the daily recommended sugar would you have drank

Answers

well this is easyyy:) you just need to multiply 4 and 2/7 by 1/2
buttt before we set up our question lets get 4 and 2/7 as an improper fraction
2
4 ----
7
we do that by multipying the 4 and 7 and then adding 2 soo lets do that
4 x 7 = 28
28 + 2 = 30
look we have our numerator!! (the top number)
and we dont have to do anything to the numerator just keep it the same as 7 :) lets look at our new improper fraction

30
------
7
see now we can set up our problem:)

  30 1
------ x -----
7 2
now all we do is multiply across:)

30 1 = 30 x 1 = 30
------ x -----
7 2 = 7 x 2 = 14
here is our new fraction

30
------
14
wait lets simplify it by dividing each number by 2

  30   ÷ 2 = 15
------
14   ÷ 2 = 7
ahh this is better here is our simpified fraction

15
-------
7
or as a decimal it is 2.142857143
either one is the correct answer:)
