-11=r+(-2) I need to solve this problem

r= -9

Step-by-step explanation:

We are given the equation:

-11 = r+ (-2)

If we want to solve for r, we must isolate r on one side of the equation.

Let's simplify the right side. A + - can just be written as -

-11= r-2

2 is being subtracted from r. The inverse of subtraction is addition. Add 2 to both sides of the equation.

-11 + 2= r-2+2

-11+2=r

-9=r

r=-9

Let's check our solution. Plug -9 in for r and solve.

-11= -9 + (-2)

-11= -11

This checks out, so we know our solution is correct.

The solution to the equation -11=r+(-2) is r=-9

10.4 inches

step-by-step explanation:

2x2x2.6

the degrees would remain the same ( the number to the left of the decimal point.

the multiply the decimal by 60 to get the minutes and use the numbers to the left of the decimal point.

then multiply the decimal portion of that by 60 for the seconds and round off as needed.

39 .956652

the 39 remains the degrees.

the minutes = 0.956652 x 60 = 57.39912

the minutes = 57

the seconds = 0.39912 x 60 = 23.95 = 24 ( rounded to nearest tenth)

so 39.956652 = 39 degrees, 57 minutes and 24 seconds

-75.159809

the -75 remains the degrees

the minutes = 0.159809 x 60 = 9.58854

the minutes = 9

the seconds = 0.58854 x 60 = 35.31, rounded to nearest tenth = 35.3 seconds

so -75.159809 = -75 degrees, 9 minutes and 35.3 seconds.

the first coordinate is north or south, since it it positive it is north.

the second number is east or west, because it is negative it is west.

39 degrees, 57 minutes and 24 seconds n

-75 degrees, 9 minutes and 35.3 seconds w
