For this case, the first thing we must do is define variables.
We have then:
n: number of journals.
We now write the equation for the profits.
We have then:
P (n) = (6-1.50) n - 600
Rewriting:
P (n) = 4.50n - 600
Answer:
An equation that represents the profit function of the newsstand is:
P (n) = 4.50n - 600
Answer: 20°
the measure of the third angle of the triangle is x ( 0 < x < 90)
because this is 3 angles in a triangle, we have:
120 + 40 + x = 180
⇔ x = 180 - 120 - 40
⇔ x = 20°
Step-by-step explanation:
Answer:
17/12 = 1 5/12
Step-by-step explanation:
The common denominator of 4 and 3 is 12.
The equivalent fraction of 3/4 is 9/12.
The equivalent fraction of 2/3 is 8/12.
Their total is 17/12 (or 1 5/12).
Answer:
Number of cookies each friend gets = 14 cookies
Step-by-step explanation:
Total cookies available for the party = 98
Number of friends invited = 7
how many did each freind get
Number of cookies each friend gets = Total cookies available for the party / Number of friends invited
= 98/7
= 14 cookies
Number of cookies each friend gets = 14 cookies
