Answer:

-8(-7r-7)+8=-272

We move all terms to the left:

-8(-7r-7)+8-(-272)=0

We add all the numbers together, and all the variables

-8(-7r-7)+280=0

We multiply parentheses

56r+56+280=0

We add all the numbers together, and all the variables

56r+336=0

We move all terms containing r to the left, all other terms to the right

56r=-336

r=-336/56

r=-6

JulsSmile [24]

Answer:

1 minute

Step-by-step explanation:

We can see that Lisa types 165 words in 3 mins.

So she types 55 words in 1 minute.

How did I work that out?

Well, all you really do is $\frac {165}{3}$ which is equal to $\frac{55}{1}$ if you divide top and bottom by 3. Anything divided by 1 is itself.
