Answer:
0.4 (not rounded)
Step-by-step explanation
You can first reduce this fraction by dividing both the numerator and denominator by the Greatest Common Factor of 18 and 45 using
GCF(18,45) = 9
18÷945÷9=25
We know that
25
is the same as
2÷5
Then using
Long Division for 2 divided by 5
gives us
=0.4
(5ac+10ab)+(-2c^2-4bc)
5a(c+2b) -2c(c+2b)
(5a-2c) (c+2b)
Answer:
3
Step-by-step explanation:
If 5/8 are eating salads, and 1/4, or 2/8 are eating sandwiches. Add 2/8 and 5/8 to get 7/8. That means only 1/8 are eating neither salads or sandwiches. Divide 24 by eight. You get 3. Since only 1/8 are eating neither sandwiches or salads you multiply 3 times one which gives you 3.
3x^2 - 7x + 9 - (2x^2 + 4x - 8).....distribute the - thru the parenthesis
3x^2 - 7x + 9 - 2x^2 - 4x + 8....combine like terms
x^2 - 11x + 17 <== this is how much less it is
x^2 - 11x + 17.....when x = 2
2^2 - 11(2) + 17 =
4 - 22 + 17 =
21 - 22 =
-1 <====
