suppose that during one period of extreme cold the average daily temp decreased 1 1/2 Fahrenheit each day how many days did it t
1 answer:
Answer:
The temperature decreased by 9 °F in <u>6 days.</u>
Step-by-step explanation:
Let the number of days it takes for the temperature to decrease by 9 °F be .
Given:
Average daily temperature decreases by °F.
Decrease of temperature in 1 day = = 1.5 °F.
∴ Decrease in temperature in x days is .
Now, as per question, decrease in temperature in 'x' days is 9 °F.
Therefore,
Therefore, the temperature decreased by 9 °F in 6 days.

The correct representations of the given inequality are

and
A number line with an <u>open circle</u> at 5 and a bold line that starts at 5 and is <u>pointing to the right</u>. The correct options are the third and fourth options
<h3>Solving inequality</h3>From the question, we are to solve the inequality
The given inequality is
–3(2x – 5) < 5(2 – x)
First, clear the brackets
–6x + 15 < 10 – 5x
NOTE: This is one of the correct representations of the inequality
Collect like terms
-6x + 5x < 10 - 15
-x < -5
Divide both sides by -1 and flip the sign
x > 5
Representing this on a number line, we get a number line with an <u>open circle</u> at 5 and a bold line that starts at 5 and is pointing to the right.
Hence, the correct representations of the given inequality are
–6x + 15 < 10 – 5x
and
A number line with an <u>open circle</u> at 5 and a bold line that starts at 5 and is <u>pointing to the right</u>. The correct options are the third and fourth options
