Answer:
C
Step-by-step explanation:
2x²-4x=0
2x(x-2)=0
either x=0
or x-2=0
x=2
so x=0,2
Answer:
23.
Step-by-step explanation:
You would multiply the 4 sizes of carpet by the 3 qualities, which equals 12. Then, you add 5+2+2+2. So it would end up being 12+11.
You can set up a proportion for this problem. Let the total number of books = x
The number of non-fiction books to the total number of books is
3/(7 + 3) books = 3/10
3/10 = 240/x Cross multiply
3x = 240 * 10 Combine the right
3x = 2400 Divide by 3
3x/3 = 2400/3 Divide
x = 800
Answer: 800 books in total.
Answer:
the length of the edge of a cube with a volume of 125 is 5.
Step-by-step explanation:
Simplifying
8a + 12b = 92
Solving
8a + 12b = 92
Solving for variable 'a'.
Move all terms containing a to the left, all other terms to the right.
Add '-12b' to each side of the equation.
8a + 12b + -12b = 92 + -12b
Combine like terms: 12b + -12b = 0
8a + 0 = 92 + -12b
8a = 92 + -12b
Divide each side by '8'.
a = 11.5 + -1.5b
Simplifying
a = 11.5 + -1.5b
