.6 * 25 = 15
.06 * 25 = 1.5
Articles of clothing that the store received last Thursday is 84
<u>Solution:</u>
Given that
A clothing donation store received numerous articles of clothing on Thursday of last week.
The number of articles of clothing that the store received last Thursday is represented by the following expression:
4 (3x − 1) − 2 (6 + 2x)
Need to calculate articles of clothing that the store received last Thursday when x = 12.5
As on Thursday x = 12.5, need to substitute x = 12.5 in above equation to get number of articles received on Thursday.
On substituting x = 12.5, we get
4 ( (3 x 12.5 ) – 1 ) – 2 ( 6 + ( 2 x 12.5 ) )
=> 4 (37.5 – 1) – 2 (6 + 25)
=> 146 – 62 = 84
On substituting x = 12.5 , we are getting value of expression as 84.
Hence articles of clothing that the store received last Thursday is 84
In a survey with 60 people, each people would get 1/60th of the chart which has 360 degrees, so everyone would get 360/60=6 degrees
and 13 people would get 13*6=78 degrees!
Ahh I hate those books; alright, check out this picture for the answers.
We have that the unit rate is 2 [Option B].
***Explanation***
We have that a proportional relationship is characterized for having the form:
Here a and b are the values that are proportional to one another and k is the constant of proportionality.
In our case we are given:
Here x & y are the proportional values and 2 is the constant of proportionality.
And, from properties of division, we have that:
