What is the value of x in the following proportion? 7/x-5 = 15/x+4

Answers

For this question you should first add -15/x on both sides of the equation and then add +5 on both sides:
7/x - 15/x = 5 + 4 
-8/x = 9 
so now you can multiply both sides by x:
-8 = 9x 
now you should divide both sides by 9:
-8/9 = x :)))

You do not buy an ice cream cone if and only if it is not hot outside.

Answers

Answer: A & D

Step-by-step explanation:

Hot Outside = Buy Ice cream cone

Buy Ice cream cone = Hot outside

A. You buy an ice cream cone if and only if it is hot outside.

This is true because you do buy ice cream when it is hot.

B. You buy an ice cream cone if and only if it is not hot outside.

This is false because you buy ice cream when it is hot.

C. You do not buy an ice cream cone if and only if it is hot outside.

This is false because you buy ice cream when it is hot.

D. You do not buy an ice cream cone if and only if it is not hot outside.

This is true because you only buy ice cream when it is hot, which means you do not buy ice cream when it is not hot.

Can someone help me with math?Come up with and describe two scenarios: one that models a direct variation situation and one that models an inverse variation situation. Do not state explicitly which scenario is which, but provide at least four data pairs for each situation. Your classmates will have to determine which of the scenarios is a direct variation and which is an inverse variation, and the value of k for each.

Answers

An example of a direct variation scenario is the increase in the income of a start-up bakeshop when the number of cakes sold increase. Example data are (4, $ 100), (5, $ 125), (6, $ 150), and (7, $ 175). 

The example of indirect variation scenario is the decrease in time it takes to reach a destination when the speed of the mobile increases. This is shown in the data points: (10 kph, 10 mins), (12 kph, 8 mins), (14 kph, 6 mins), and (16 kph, 4 mins). 

Answer:

Direct
