Solve the following 19+n=30

n=11

Step-by-step explanation:

In order to solve this equation, we need to find out what n is. We have to get n by itself on one side of the equation. Perform the inverse operations to both sides of the equation.

19+n=30

19 is being added to n. The inverse of addition is subtraction. Subtract 19 from both sides.

19-19+n=30-19

n=30-19

n=11

Let's check out solution. Plug 11 in for n in the original equation.

19+n=30

19+11=30

30=30

The statement above is true, so we know our solution is correct.

location: point 0

step-by-step explanation:

well, -8 to 10 on a number line is 18 spaces.

1/9 of 18 is 2.

so, 4/9 of 18 must be 8.

8 spaces from -8 (a) is 0.

so, 4/9 of the way from -8 to 10 is 0!

they are simplified
