Answer:The height of one book is

in
Explanation:We know that the 3 books are of the same size. This means that the 3 books have the same height.
Assume that each book has a height x in
Now, we know that the total height is 10 in.
Therefore:
x + x + x = 10
3x = 10
x = 10/3 in
Based on the above, the height of one book is 10/3 in
Hope this helps :)
Expanded form just means to expand the number out. To change this in to expanded form you just need to do the following:-
1.000 + 0.0 + 0.07 + 0.005 = 1.075.
Hope I helped ya!!
Answer: (1, 0) or 1
Step-by-step explanation:
Since it is parallel to y=2x-7 that means it has the same slope but a different y-intercept. Let's use b for the unknown value
6=2(4)+b
6=8+b
6-8=8+b-8
-2=b
Now we know the equation for the line is y=2x-2
Since we are looking for the x-intercept y will be 0 and we can sub that in to solve

The x-intercept is 1
Answer:
1) 
2) 
3) x=30
4) x= -4/3
Step-by-step explanation:
Use the Pythagorean theorem to find the missing angle.
In the formula, the c is the length of hypotenuse, so


20*9=6x
180=6x
x=30
4(3x+2)=6x
12x+8=6x
6x=-8
x= -4/3
Step-by-step explanation:

that's it
