Help me 9th grade math need answer ASAP very appreciated thank you

64

Step-by-step explanation:

Let the tens digit be x and units digit be y. We can write the number we are finding as 10x + y. We also know that x + y = 10 and 10x + y - (reversed number) = 10x + y - (10y + x) = 9x - 9y = 18.

Dividing by 9 on both sides, we get:

x - y = 2

Using the equations x + y = 10 and x - y = 2, we find that x = 6 and y = 4. So the number is 64.

I hope this helps! :)

step-by-step explanation:

when a number is between two straight lines it means the absolute value.

to find absolute value you need to know how many numbers is that number away from 0.

when finding absolute value the number will always come out positive

so absolute value of -3 is 3

absolute value of 3/2 is 3/2

absolute value of -2 is 2

absolute value of 3.5 is 3.5

absolute value of -1 is 1

now put these numbers in order:

a)   |-1|, |3/2|, |-2|, |-3|, |3.5|
