What is the value of r in the equation 4r − 8 = 5r + 12?

To find r, we have to isolate it on one side of the equation. We can do this by "undoing" the equation one step at a time.

4r - 8 = 5r + 12

4r - 8 - 4r = 5r + 12 - 4r

-8 = r + 12

-8 - 12 = r + 12 - 12

-20 = r

r = -20

Hope this helps!

Answer:

r= -20

Step-by-step explanation:

you need to solve this equation for the variable <em>r</em>, which means you need to get <em>r </em>alone on one side of the equation.

4r-8=5r+12

subtract 4r from both sides

-8=5r-4r+12

-8=1r+12

subtract 12 from both sides

-8-12=r

simplify

-20=r

Given:

The limit problem is:

\lim_{x\to 3}(x^2+8x-2)

To find:

The limit of the function by using direct substitution.

Solution:

We have,

\lim_{x\to 3}(x^2+8x-2)

Applying limit, we get

\lim_{x\to 3}(x^2+8x-2)=(3)^2+8(3)-2

\lim_{x\to 3}(x^2+8x-2)=9+24-2

\lim_{x\to 3}(x^2+8x-2)=33-2

\lim_{x\to 3}(x^2+8x-2)=31

Therefore, the correct option is D.
