Answer:
13 inches
Step-by-step explanation:
Perimeter is all the sides added so your equation would be 8+8+x+x=42 then you combine like terms. 16+2x=42. Next you would isolate the variable 2x=26 and the divide the 2 on both sides and you get x=13. Meaning your width is 13 inches long

Answer:
800 cubic inches
Step-by-step explanation:
So all we need to do is:
1) find the volume of 1 cube
2) multiply it by 100, because 100 cubes make up the prism
SO 1)
The volume of cube = side * side * side = 2*2*2 = 8 cubic inches
SO 2)
The volume of prism = 100 * vol(cube) = 100 *8 = 800 cubic inches
ANSWER: 800 cubic inches
Hey there!
Let's first evaluate this problem, and the keyword we need to use. The problem says that out of the total number of bracelets Brianna has, x, 1/3 of them are pink. The reason the word of is so important throughout math is that it signifies multiplication. For example, 1/2 of 10 is 5 because 1/2 times 10 is 5.
Now, to apply that to this situation, we need to create an equation, a mathematical statement that indicated the equilibrium or equality of two values. Since we have 1/3 of all her bracelets, x is four, we can set up our equation. Here's another good keyword- is. Is signifies an equation, because it means "equal to" mathematically. For example, 5 is equal to 20/4.
We have:
1/3(x) = 4
(One-third of x, the total amount of bracelets, is four.)
We don't want that fraction there. In order to get rid of it and keep the expression equal, we multiply both sides by 3. We have,
x = 12
Hope this helps!
