Answer:

B - 600 words in 12 minutes

Step-by-step explanation:

So most of this has to do with division. So let's look at answer one

320 words in 8 mins

320/8 = 40 words per minute.

600 words in 12 minutes

600/12 = 50 words per minute

350 words in 8 minutes

350/8 = 35 words per minute

And finally, 225 words in 5 minutes

225/5 = 45 words per minute. Thus, the answer is B

Find the angles y and x​
Katen [24]

Answer:

x = 67

y = 23.5

Step-by-step explanation:

Sum of angles in a triangle is supplementary,

x + 90 + 23 = 180

x + 113 = 180

x = 180 - 113

x = 67

y = ?

180 - 67 / 2

= 133 / 2

= 66.5

y + 66.5 = 90

y = 90 - 66.5

y = 23.5
