Answers

Answer:

4.5

Step-by-step explanation:

18 / 4 = 4.5

Okay, you would know that 16 / 4 = 4.
So that solves 1 part. Next, you have to divide 2 / 4. Which would equal 0.5.

Then you add 4 to 0.5, which is 4.5!

anyone know inverse operations, cause I am confused, I looked online and it said
Example: 20 + 9 = 29 can be reversed by 29 − 9 = 20 (back to where we started)
And the other way around:

Example: 15 − 3 = 12 can be reversed by 12 + 3 = 15 (back to where we started)
so like when do we do the 2nd way or can we just do either one of them???

Answers

Answer:

For inverse operations, it helps make solving equations easier. Say if you'd rather add than subtract, then you can do the inverse of a negative equation.

Inverse operations are also very helpful for linear equations.

To find the inverse of an equation, we change the plus sign to a negative sign. Then, we switch the first number and the answer.

Ex:

13 - 2 = 11    (now change plus to minus)

13 + 2 = 11      (not the answer yet)

Now we switch the first number with the answer!

11 + 2 = 13

Hope this helped, I tried to explain it easily.

11+2=13 that’s the answer maybe

Jamaya is solving a riddle in order to find a mystery number. She knows the number is negative, and that the sum of 1/4 of the number and 2 is equal to the sum of 1/2 of the number and 4. What is the mystery number?

Answers

Answer:

x = -4

Step-by-step explanation:

let x equal the number

so

1/4(-x)+2=1/2(-x)+4

-1/4x + 2 = -1/2x + 4

+1/2x          +1/2x

1/2x + 2 = 4

        -2    -2

1/2x = 2

x = -4

Answer: x=-8

Step-by-step explanation:

1/4x+2=2x+16

Multiply by four to get rid of the fractions

X+8=2x+16

Combine like terms

-x=8

x=-8
