A number cube with the numbers 1 through 6 is rolled. What is the probability of the number cube showing either a 1 or an even number

4/6 or 2/3

Step-by-step explanation:

Half of the dice has even numbers and the other has odds so because of that it already gives you a 3/6 or 1/2 chance of getting an even. And the one for getting would be a 1/6. But because we already have the evens for 3/6 we can then add the 1/6 to get 4/6 or 2/3

2/3 is the awnser

Step-by-step explanation:

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:

4a. is 3 miles every hour

4b. is 1/3 of an hour per mile
