The answer would be -3. if x is -3, then in the equation x2 - x, we would replace both x with -3. So then it would be -3 times 2 minus -3 And if we multiply -3 times 2 we get -6 and -6 minus -3 is -3. I hope this helped you, sweetheart.
To write a ratio as a fraction, we simply take the first number in the ratio and make it the numerator while taking the second number in the ratio and making it the denominator.
Because we want the ratio of engines to box cars, our ratio should be:
number of engines/number of box cars
When we substitute in our respective values, we get:
4/18
To simplify this ratio, we have to find the GCF, or greatest common factor of the numerator and the denominator, which in this case is 2. To simplify, we divide both the numerator and the denominator by the GCF, as follows:
4/2 / 18/2
When we simplify, we get:
2/9
Therefore, your answer is 2/9.
Hope this helps!
Purple flowers: black flowers = 4:8 = 108
4 + 8 = 12
108 / 12 = 9.
9 x 4 = 36.
36 of the flowers are purple.
1 quart ---- 2 pints
24 quarts -x
x=24*2/1=48 pints
or
24quarts*(2 pints/1 quart)=48 pints
