Answer:

Equation: x-(-2)=21

Solution: x=19

Step-by-step explanation:

A number decreased by -2 is equal to 21.

Let's call the number,x. Decreased means we are going to subtract.

x-(-2)=21

-(-2) is just +2:

x+2=21

Subtract 2 on both sides:

x=21-2

Simplify:

x=19

So if 19 is decreased by -2 we should get 21.

Neporo4naja [7]

Complete question :

Carly purchased 9 1/2 pints of ice cream for a party. If each guest will be served exactly 3/5 pint of ice cream, what is the greatest number of gusts that Carly can serve

Number of guest that can be served :

Total pints / fraction per guest

9 1/2 ÷ 3/5

19/2 * 5/3

95 / 6

= 15.8 guest

Hence, greatest Number of guest that can be served = 15
