Answer:
-21 < 3x < -6
OR -6 > 3x > -21
Step-by-step explanation:
Take a part each section of the word form. Translate each section into algebraic form (numbers and symbols) and put the sections back together.
"Three times x": 3x A number and variable together multiply
"is less than -6": < -6
"and greater than -21": > -21
When writing that a number is > or <, you can also write the number on the other side, change the symbol, and it will mean the same thing.
< -6 is the same as -6 >
> -21 is the same as -21 <
<u>The number remains on the same open or closed side of the symbol.</u>
The problem tells use that "3x" is between -21 and -6. Put the sections back together, but write 3x in the middle.
-21 < 3x < -6
You can also write:
-6 > 3x > -21
You can write them either way, but some teachers prefer smaller number to bigger number from left to right.

Step-by-step explanation:
It is 8 combination 4- using a TI 84, type in 8, then hit math- over to probability then nCr- then 6
If the price-elasticity of demand for chips is 0.75, then a 20 percent increase in price would result in a 15 percent decrease in the demand quantity.
As per the question statement, the price-elasticity of demand for chips is 0.75 and there is a 20 percent increase in price.
We are required to calculate the resulting decrease in the demand quantity by percent, based on the conditions mentioned in the statement above.
Here, given Price-Elasticity of Demand
= 0.75
Also given the percent increase in price = 20
Now, we know that,
= [(Percentage change in quantity demanded)/(Percentage change in price]
Or, [0.75 = (x/20)]...[Assuming "Percentage change in quantity demanded" to be "x"]
Or, [x = (20 * 0.75)]
Or, [x = 15]
That is, If the price-elasticity of demand for chips is 0.75, then a 20 percent increase in price would result in a 15 percent decrease in the demand quantity.
- Price-Elasticity of Demand: Price Elasticity of Demand is a measurement of the change in the consumption of a product in relation to a change in its price and is expressed mathematically as the quotient of (Percentage Change in Quantity Demanded) divided by (Percentage Change in Price)
