Answer:

The equivalent expression can be -5r+5 or 5(-r+1).

Step-by-step explanation:

Consider the provided expression.

-5+(-5r)+10

Open the parentheses as shown.

-5-5r+10

Arrange the like terms together as shown.

-5r-5+10

Now subtract the like terms as shown.

-5r+5

Or

5(-r+1)

Thus, the equivalent expression can be -5r+5 or 5(-r+1).

3/4(8x-4)=7x+2, I need to find out the answer
laiz [17]

Answer: x = -5

Step-by-step explanation:

First convert 3/4 to decimal= 0.75

0.75 (8x - 4) = 7x + 2

6x - 3 = 7x + 2

Transpose 7x from right hand side to the left hand side

6x - 7x = 2 + 3

-x = 5

x = -5

What is the value of the expression?<br> 1/3-5/6<br> Enter your answer in simplest form.
algol [13]

Answer:

(1/3 - 5/6) / 5/6

You want to make 1/3 and 5/6 have the same denominator so you multiply both the numerator and denominator of 1/3 by 2 to get 2/6. You plug that back into your equation to get: (2/6 - 5/6) / 5/6. 2/6 - 5/6 is -3/6. -3/6 divided by 5/6 is -3/6 multiplied by 6/5 which is -3/5.

A line contains the two points plotted in the coordinate plane below.
Andrew [12]

Answer:

The slope would be 3.

Step-by-step explanation:

The formula for finding slope is \frac{y1-y2}{x1-x2}
We can plug these numbers into the equation by doing \frac{1--5}{2-0}
1--5 is equal to 1+5, which is 6.
2-0 is equal to 2.
\frac{6}{2} is 3, which is how you get your answer.
I hope this helps! :)
