Answer:
21 Books in total
Step-by-step explanation:
If you just want the total number of books, here:
If each student has 3 books, and there are 7 students, we can create the equation: 7 * 3 :because this is showing that 7 people each have 3 books
7 * 3 = 21 so There are 21 books in total
Another we could write it is 3 + 3 + 3 + 3 + 3 + 3 + 3 because there are 7 students with 3 books each. Adding this up would equal 21.
Answer:
a = 15
Step-by-step explanation:
The formula to solve for the above diagram is given as:
Sum of the interior angles in a circle = 360°
(10a - 4)° + (6a - 2)° + (8a + 6)° = 360°
10a - 4 + 6a - 2 + 8a + 6 = 360
24a -6 + 6 = 360°
24a = 360
a = 360/24
a = 15
The volume of this prism would be 294 cubic units.
To determine this you can use the given perimeter of 28 to create combinations of dimensions of a recatangule prism.
I started with 7 + 7 + 7 + 7 to get 28. This means the length and width were both 7 units.
This would make the dimensions of this prism 7 x 7 x 6(the height).
The find the volume multiply all three numbers.
The volume is 296 cubic units.
Answer:
14a + 8b
Step-by-step explanation:
First, you need to combine like terms.
4a + 10a = 14a
12b + (-4b) = 8b
14a + 8b
