Jane is helping the librarian stack books on some new shelves. She is to stack 116 books on 16 shelves. The librarian told her to put the same number of books on each of the 16 shelves.

Describe one way that Jane can use to determine the number of books she should put on each shelf.

Answers

Answer:

She should divide The total of books to the total of shelfs

Step-by-step explanation:

Answer:

she can put 7 on each shelf with 4 left over.

Step-by-step explanation:

You divide 116 by 16, which is 7.25 and 1/4 of 16 is 4. So you know you have 4 leftover.

Consider this equation.

7.8 + 2(0.75m + 0.4) = -6.4m + 4(0.5m - 0.8)


Mia solved the equation and determined that m = 2. Is she correct?

Answers

Answer:

No, Mia is not correct, the answer is -2.

Step-by-step explanation:

First we are going to use the distributive Property.

Step 1: 2(0.75+0.4). multiply the 2 out. .75m x 2=1.5m and 2 x .4= .8.

We get 1.5m+.8, so 2(0.75+0.4)=1.5m+.8

Now we are going to distribute on the oher side. 4(.5m-.8)

4x .5m=2m and 4x.8=3.2. Keep the sign the same and we get 2m-3.2, so 4(.5m-.8)=2m-3.2

We put this into the new equation to get 1.5m+.8+7.8=-6.4m+2m-3.2

Step 2: combine like terms

.8+7.8= 8.6 and -6.4m +2m =-4.4m

Plug that into our equation and we get 1.5mn+8.6=-4.4m-3.2

Step 3: Switch the sides

Bring -4.4m to the other side to get 1.5m+4.4m=5.9m

One side is 5.9m

We bring 8.6 to the other side to get -8.6. now we do -3.2-8.6=-11.8.

Our new equation is 5.9m=-11.8

divide by 5.9 on both sides to get our answer of

m=-2

no she’s wrong the answer is (-2)

Choose the following ratios as a percent: 30 days out of 100 days
10%
30%
100%
3%

Answers

Answer:

30%

Step-by-step explanation:

30% of 100 in simple terms stands for; "Thirty percent of a hundred."

This shows the ratio percentage correctly. And other choice would not be correct.

100% of 100 has nothing to do with 30.

3% is "three percent of 100." And again, has nothing to do with thirty.

10% also has nothing to do with thirty.

6. When Landon saves $15 more, he will have enough money to buy a basic MP3 player. The player he wants to buy costs $199, which is 4 times the cost of the basic player. Which equation could be used to determine n, the number of dollars Landon has already saved?

A. 4n +15 = 199 B. 4(n+15) = 199 C. n + 4(15) = 199

Answers

Answer:

A) 4n+15=199

Because n is the cost of the basic player, so 4*n would be the cost of the player he wants. Also +15 since he needs 15 more dollars.

The coordinates of a point on a coordinate grid are (−1, 5). The point is reflected across the x-axis to obtain a new point. The coordinates of the reflected point are (1, −5) (−1, 5) (1, 5) (−1, −5)

Answers

Answer:

I think it should be (-1,-5)

Step-by-step explanation:

On a coordinate grid, when you flip this coordinate across the x-axis, the x-axis number won't change, meaning that -1 will stay. The intial number was in the second quadrant, this means that the new number will be in the third quadrant which is made up of all negative numbers. This means that 5 will now be graphed as negative 5, making (-1,-5) the correct answer in this situation.
