Answer:
B
Step-by-step explanation:
This is Unit rate,s o you divide to find the word per minute which is the unit or 1
A. 320 words in 8 minutes; = 320/8 = 40 words/min
B. 600 words in 12 minutes; 600/12 = 50 words/min
C. 350 words in 10 minutes; 350/10 = 35 words/min
D. 225 words in 5 minutes: 225/5 = 45 words/min
B - 600 words in 12 minutes
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
The answer is 2.3 right.
Answer:x=1
y=y
y = -x + 10
y = 7x + 2
-x+10=7x+2
10=8x+2
8=8x
x=1
44
22 for every six kids
12 is 6 doubled so you double 22 to get 44
x = 67
y = 23.5
Sum of angles in a triangle is supplementary,
x + 90 + 23 = 180
x + 113 = 180
x = 180 - 113
y = ?
180 - 67 / 2
= 133 / 2
= 66.5
y + 66.5 = 90
y = 90 - 66.5
