katen-ka-za [31]

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

Help T-T
Reil [10]

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.

DIA [1.3K]
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 =
