The amount of pounds of vegetable needed in fractions to make the stew exactly 10 pounds is 3 3  / 8 pounds

<h3>How to solve fractions?</h3>

The amount of pounds of vegetable needed to make the stew exactly 10 pounds can be calculated as follows:

potatoes weight = 2 7 / 8 pounds = 23 / 8 pounds

green beans weight = 1 1 / 4 = 5 / 4 pounds

pepper weight = 2 1 / 2 = 5 / 2 pounds

Therefore,

weight needed = 10 - 23 / 8 - 5 / 4 - 5 / 2

weight needed = 80 - 23 - 10 - 20 / 8

weight needed = 80 - 53 / 8

weight needed = 27 / 8

weight needed in fractions to make the stew exactly 10 pounds = 3 3  / 8 pounds

X2 can be combined with X?
natulia [17]

Answer:

Your first instinct might be to go ahead and add the x terms together, BUT this would be a bad thing to do! You cannot combine the x2 and 2x, because the first term has an exponent (2) and the second one does not have an exponent; therefore, you cannot add them together!
