Answer:
x = 6
Step-by-step explanation:
5x-3 = 2x+15
<h3>i) move 2x to the left-hand side and change its sign</h3>
5x-2x-3 = 15
<h3>ii) move -3 to the right-hand side and change its sign</h3>
5x-2x = 15+3
<h3>iii) collect like terms</h3>
3x = 15+3
<h3>iv) add the numbers</h3>
3x = 18
<h3>v) divide both sides of the equation by 3</h3>
Answer:
You will have 5-2=3 apples.
Answer:

The relationship between temperature and the coffee sales is a negative exponential of temperature
<h3>
What is relation?</h3>
relation is subject of order between to sets or how the connected to each other.
The temperature of liquid is essential in the process of brewing because its affects the rate of evaporation or extraction. it refers to the test and matters that are dissolved from the coffee beans. The hot is the water, the quick it is to extract. At a high temperature, it’s tougher to control the rate of extraction. This can lead to over-evaporation of liquid, making your coffee taste too bitter since the heat strips away a lot of oxygen.
since the temperature varies over the year, which implies the taste of coffee also vary in a manner that in cold days people love coffees and in hotter days the people love to drink cold drinks instead of coffees
so in cold days the sales of coffees is grater in comparison with hot days
Thus the relationship between the sales of coffees and temperature is negative exponential of temperature.
