When a number is a multiple of 2 what are the possible values for the ones digit

Answers

Answer:

The correct answer is 2,4,6,8 and 0.

Step-by-step explanation:

A number is considered a multiple of 2 when it contains the number 2 repeated several times.

For example the number 8, contains the number 2 repeated 4 times = 2 + 2 + 2 + 2 = 8

It can also be a multiple of 2, any number multiplied by two. For example 6 is a multiple of 2 since 2x3 = 6

In simple words, all even numbers, or all numbers multiplied by 2, are multiples of 2.

2x0 = 0

2x1 = 2

2x2= 4

2x3 = 6

2x4 = 8

2X5 = 10 ...

The possible values for the ones digit are 0, 2, 4, 6, or 8.

Divide by 3 both sides

$216/3=x$

Rewrite

$x=72\ cm$

A ceramic artist can shape a pot in 3 minutes. It takes 10 minutes to fire one batch of pots in the kiln. If there are p pots in a batch, which expression represents the time it takes to shape and fire one batch of pots? How long will it take the potter to form and fire a batch of 10 pots?The expression is 3p. It takes 30 minutes to shape and fire 10 pots.

The expression is 3p − 10. It takes 20 minutes to shape and fire 10 pots.

The expression is 3(p + 10). It takes 60 minutes to shape and fire 10 pots.

The expression is 3p + 10. It takes 40 minutes to shape and fire 10 pots.

Answers

3p + 10 (40 minutes)

3p+10. 3 minutes per pot to shape it. Time taken to shape all p pots is 3p. Then it takes 10 minutes to fire the batch.
