Answer:

there are 24 cookies in the 4 boxes

there are 6 cookies in each box

Step-by-step explanation:

Let x = number of cookies in each box

If there are 4 boxes, the total number of cookies in the four boxes are 4x

If a friend brought 1 cookie to add to each box, the friend brought a total of 4 cookies

4x + 4 = 28

Solving for x

4x = 28 - 4

4x = 24

x = 6

Each box contains 6 cookies and there are 24 cookies in 4 boxes

Would you multiply M by the third equation (6x^5.....) since it is subtraction
steposvetlana [31]

Answer:

B

Step-by-step explanation:

Here, we want to get the value of m

The value of m can be obtained by multiplying the first factors of the first two polynomial, subtracting the first factor of the third and equating to 18

So what we have will be;

m * 6 - 6 = 18

6m -6 = 18

6m = 18 + 6

6m = 24

m = 24/6

m = 4

Aleena has a savings account that gives 5% annual interest. She deposits $200 that she received on her birthday. Write an equati
ANTONII [103]

Answer:the equation is 200 + 10x

Step-by-step explanation:

The formula for simple interest is expressed as

I = PRT/100

Where

P represents the principal or initial amount deposited into the account.

R represents interest rate on the principal

T represents time in years

I = interest after t years

From the information given

T = x years

P = $200

R = 5%

Therefore

I = (200 × 5 × x)/100

I = 1000x/100

I = 10x

Therefore, the equation representing the total amount of money that would be in the account after x years would be

200 + 10x

Please answer questions 7 and 9!! I need help and show work and explain
Julli [10]

Hey!

Hope this helps...

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

<em>Question 7:</em>  Is the Graph a 1-to-1?

The answer is: No

<em>Reason: </em>If you look at the graph, you see that when the x value is -1 the y value is -2, when x is 0, y is 0.  When x is 1, y is 2, when x is 3, y is 4, and so on and so on...


<em>Question 9:</em> What is f(2)?

The answer is: When f (or x) is 2, y is 3... so f(2) = 3

<em>Reason:</em> (Look at reason for Question 7)


I hope this helped, if it did, please do not forget to give a "Thanks" and a 5 star rating...

And as always, thanks for using Brainly...
