keeping in mind that vertical angles are always congruent.

\stackrel{\measuredangle A}{7x-6}~~ = ~~\stackrel{\measuredangle B}{8x-27}\implies -6=x-27\implies 21=x~\hfill \underset{\measuredangle B}{\stackrel{8(21)~~ - ~~27}{141}}

Robert ran 3 1/3 mph for 3/4 of an hour. How far did he run?​
matrenka [14]

Answer:

2 ½ miles

Explanation:

mph = miles per hour, which means that if robert had run for the full 1 hour, he would have run 3 ⅓ miles.

however, since he only ran for ¾ of an hour, which is equal to 0.75, we can multiply the 3 ⅓ miles by 0.75 to get 2.5 or 2 ½ miles.

i hope this helps! :D

Select all expressions that can be subtracted from 9x to result in the expression 3x+5.
Arte-miy333 [17]
<h2>Answer:</h2><h2>The expressions that can be subtracted from 9x to result in the expression 3x+5 is 6x - 5</h2>

Step-by-step explanation:

To find the expression that can be subtracted from 9x to result in the expression 3x+5.

Let us consider the expression, a - b = c

Here a = 9x

the result, c = 3x + 5

b = ?

Substitute the values in the above equation, we get

9x - b = 3x + 5

9x - (3x + 5) = b

b = 6x - 5

Paul [167]
No, it does not seem reasonable. The quarterly statement reports an increase of $47, so it would be a positive rate of return on the investment instead of a negative rate.

Ann [662]

There are two ways to list the angles:

1) Simply name them based on the points:

∠W , ∠X , ∠Y , ∠Z

2) The way that I believe that you are supposed to list them in this case. List them as such:

∠WYZ , ∠YZX , ∠ZXW , ∠XWY
