Number 19. Anyone know how to solve it?

Well it is D 16

Step-by-step explanation:

First of all, 4^2 is 4*4 because it is the power of 2 so you multiply the number by itself 2 times.

For example, I will make a random problem 2^4 some people might think it is 8 but it is not you are supposed to multiply 2 by itself 4 times so it will be 2*2*2*2 which is 16

Hope this helps and hope the example makes sense!

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.
