3 0

Hello!

You can put down all the single digits that add to 12

3 + 9 = 12
4 + 8 = 12
5 + 7 = 12
6 + 6 = 12

The possible numbers are 39, 48, 57, or 66

You flip all the numbers and find out if it goes up by 36

93 - 39 = 54

It is not 39

84 - 48 = 36

Since it went up by 36 the answer is 48

The answer is 48

Hope this helps!

Find x (steps pls) | x - 7| = 2 (i dunt understand the | in the questions)

kirill [66]

these two bars | | mean absolute value

here's how to find x

| x - 7| = 2

first apply the absolute rule

x - 7 = 2 x - 7 = -2

in both equations add 7 on both sides

x - 7 + 7 = 2 + 7 x - 7 + 7 = -2 + 7

then simplify the expressions

x = 9 x = 5

now combine these two solutions to get your answer

x = 9 or x = 5

hopefully my explanation helps
