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.

$25

step-by-step explanation:

25 - 4.50 = 20.5

20.5 / 2 = 10.25

10.25 + 10 = 20.25

20.25 - 12.50 = 7.75

therefore the answer is $25 as shown as the first number.
