Which expression is equivalent to 5x+10y-15? 5(x-2y-3)
5(x +5y-10)
5(x+2y-3)
5(x+2y-15

Your answer would be C.

Step-by-step explanation:

5(x+2y-3)

You would want to multiply 5 times x keep the x, 2 times 2 keep the y, 5 times -3 keep the negative.

so should look like this.

5x+10y-15

then add 15 to the negative 15 and that will cancel out, add 15 to the 5x

should look like this when you get done doing that.

20x+10y

subtract the 10y from the 10y and it will cancel, subtract the 10y from the 20x and the y will go away.

answer is

10x

if you where to solve the question

5x+10y-15

you would get

10x.

Thank you for your time.

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
