Arestaurant had n kg of sugar in its stock. then, 5 kg sugar was used to make the first dessert on
the menu. next, 3 kg sugar was used to make the second dessert on the menu. write an
expression to show how many kilograms of sugar were left in the stock, and then simplify the
expression.

Expression showing the sugar left is kg.

Step-by-step explanation:

We are given that,

Total number of sugar in the stock initially = n kg

Amount used for making 1st dessert = 5 kg

Amount of sugar left = kg

Again, Amount used for making 2nd dessert = 3 kg

Amount of sugar left = kg

i.e. Amount of sugar left = kg

Thus, the expression showing the sugar left is kg.

75 tickets have been sold so far.

step-by-step explanation:

in this question it is clearly mentioned that 45 children's tickets have been sold and this number is 60% of the total tickets sold.

now let's assume the total number of tickets sold be x.

then 60% of x = 45

⇒

⇒ x(.6) = 45

by dividing with .6 on both the sides of the equation

⇒ x = 75

therefore 75 tickets have been sold so far.

2 is the final ! : )
