Delicious77 [7]

Answer:

If he kept taking notes at the same pace, he would have 16 pages of notes in his notebook.

Step-by-step explanation:

By dividing the number of pages of notes taken by the time spent taking them, you can find his rate of note-taking, which is 4 pages an hour. By adding another hour of notes, he should have 16 pages of notes. But if this question is asking for 4 more hours, the answer would be 28 pages.

Alex has a grid in the shape of a rectangle. he has right triangles. each right triangle has an area of 25 square millimeters an
Maurinko [17]
First you have to find the area of the rectangular grid. The area of a rectangle is length•width.
So:
A= 20•12
A= 240cm
Then you need to convert 240cm into mm.
240cm is 2400mm.

Then you need to figure out how many triangles can fit into the rectangle if all the triangles have an area of 25mm. So you divide 2400 by 25.
2400:25= 96

So Alex can fit 96 triangles into the grid.

What is the solution to the system of equations graphed below?
Soloha48 [4]
Short Answer B
Remark

You need not do any calculations to get the answer. You are required just to read the graph. Doing the calculations would be beneficial but unnecessary.

Step One
Find the x value.
1. If you have a ruler or a straight edge of some kind, put it on the cross point of the two graphs.
2. Make the ruler go straight up and down. You will find out it goes 1 point back of the 5.
3. Count the number of squares from 0,0 or when y = 0.
4. You will find you have to count 4 squares along the x axis. 

The x value is 4.

Step Two
1. Put the ruler on the cross point again. This time make it go straight across. 
2. Count up from (0,0)
You should get 8.

The y value is 8

Answer: (4,8)
