Find the mean of this set of numbers.

1 answer:

4 0

The answer would C. You must remember for the mean you need to add up all of the numbers, then divide the answer by the number of numbers you have.
Ex:
5,3,7,2,1
All of these numbers added up together is 18.In order to find out the mean, we need to divide the answer(18) by 5 because there are 5 numbers.
Hope this helps!

Brooke is reading a 379-page book. She has already read 54 pages, and she can read 28 pages in an hour. If h represents the numb

Dafna1 [17]

Answer:

28x + 54 = 379 is what I came up with, though it would help to see the choises you have to select from if there are any.

Step-by-step explanation:

28 = the pages she reads in 1 hours.

x = how many hours it would take to finish the book.

54 = the amount of pages she's already read.

379 = the full amount of pages she needs to read to finish the book.

I really need help asap please

We can use the substitution method to solve this problem.

The second equation is $\sf y=2x$ , so we can plug in 2x for 'y' in the first equation:

$\sf 5x-2y=3$

$\sf 5x-2(2x)=3$

Multiply:

$\sf 5x-4x=3$

Combine like terms:

$\sf x=3$

This is the x-value of our solution, we can plug this into any of the two equations to find the y-value:

$\sf y=2x$

$\sf y=2(3)$

Multiply:

$\sf y=6$

This is the y-value of our solution. So our entire solution is (3, 6).
