1/4= .25 For an example. Also 1/5= .2 and 1/2= .5
Answer:
<em>Zeina had 35 books and Ali had 5 books</em>
Step-by-step explanation:
<u>Equations</u>
We know Zeina has seven times as many books as Ali. If we call
x = Number of books Ali has
Then Zeina has
7x = Number of books Zeina has
We also know if Zeina gave Ali 15 books, they would have the same number of books, thus:
x + 15 = 7x - 15
Adding 15:
x + 15 +15 = 7x
Subtracting x:
15 +15 = 7x - x
Operating:
30 = 6x
Dividing by 6:
x = 30 / 6
x =5
7x = 35
Thus Zeina had 35 books and Ali had 5 books
Answer:
We know that opposite sides of rectangle are parallel to each other then the pathway makes a traversal.
Then A + 79° = 180° (Consecutive Interior angles)
A = 101°
The line of best fit is a line that follows the direction of the dots. It doesn't have to be perfect, it's just a general line to represent the data. Sometimes there isn't a line of best fit (if there is no correlation). It normally touches most of the dots.
The slope is about 1/2 and the point where the line touches the y axis is at 40 so that means an equation could be y = 1/2x + 40
When the advertising expenditure (x value) is 18,000, substitute it into the equation above. y = 1/2(18,000) + 40 which equals y = 9,040 . This is the expected revenue.
Hope this helps!
