Answer:

3x²+4x-2

Step-by-step explanation:

\frac{x+2}{2}-\frac{x+1}{3x} are not like terms. To make them like terms, you have to multiply the first fraction by 3x, and the second by 2.

This makes it \frac{3x(x+2)}{6x}-\frac{2(x+1)}{6x}, which can be expanded to \frac{3x^{2}+6x}{6x}-\frac{2x+2}{6x}.

This can be simplified to \frac{3x^{2} +4x-2}{6x}.

The numerator is therefore 3x²+4x-2.

Elena-2011 [213]
1.54 + 2.37 

= (1 + 5/10 + 4/100) + (2 + 3/10 + 7/100)

= 1 + 5/10 + 4/100 + 2 + 3/10 + 7/100

= 3 + 8/10 + 11/100

= 3 + 8/10 + (10/100 + 1/100)

= 3 + 8/10 + (1/10 + 1/100)
= 3 + 8/10 + 1/10 + 1/100

= 3 + 9/10 + 1/100

= 3.91

Answer:

250 jars

6 hours

Step-by-step explanation:

We know they make 50 jars in an hour, so 50 times 5 is 250 jars in 5 hours. Since 300 is 50 more than 250, and we know 50 times 6 is 300, we can say that we would need 6 hours to make 300 jars.
