|-13\ = -(-13)<br> True False?
kolbaska11 [484]

Answer:

This statement is true.

Step-by-step explanation:

The absolute value is how far the number is from zero, so how many steps will it take on a number line to get from that particular number to zero?

Since you can't have negative steps, The -13 in absolute value would be 13.

The -(-13) is the same thing as saying  -1 ( -13 ). Since negative times a negative is a positive, 13=13 is a true statement.

Four times the dference of a number and three is twelve find the number
3241004551 [841]

the number is 6

let the number be n , then the difference of this number and 3 is n - 3

4 times this is 4(n - 3) = 12 ( solve for n )

divide both sides by 4

n - 3 = 3 ( add 3 to both sides )

n = 3 + 3 = 6

the number is 6
