Cristiano has 42 apples in his bag and his brother has only 16. How many apples should Cristiano give his brother so they both have the same number of apples?

13

Step-by-step explanation:

Total number of apples:  42 + 16 = 58

For each brother to have the same number of apples:  58/2 = 29 apples each

Therefore, to calculate the number of apples Cristiano has to give his brother, subtract 29 from the original number of 42 apples:

42 - 29 = 13

Step-by-step explanation:

We know that:

Since Cristiano has more apples than his brother, Cristiano must give his apples to his brother. Let's name Cristiano as C and his brother as B.

This means that when Cristiano has equal apples to his brother, they will have 29 apples.

Hence, Cristiano gave 13 apples to his brother.

the image of (6, 9) under a dilation is (4, 6). the scale factor is

mr. flanders’ class sold 47 doughnuts and   mr. rodriquez’s class sold 38 cartons of milk

step-by-step explanation:

let x be the number of doughnuts sold by mr. flanders’ class and y be the number of cartons sold by mr. rodriquez’s class.

1. together, the classes sold 85 items, then

x+y=85.

2. both classes earn earned $104.49 for their school. if doughnuts were sold for $1.35 each, then x doughnuts costed $1.35x. if cartons of milk were sold for $1.08 each, then y cartons costed $1.08y. hence,

1.35x+1.08y=104.49.

3. solve the system of two equations:
