Suppose that during one period of extreme cold the average daily temp decreased 1 1/2 fahrenheit each day how many days did it take for the temp to decrease by 9 degrees fahrenheit for barrow alaska

The temperature decreased by 9 °F in 6 days.

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.

let's solve your equation step-by-step.

4x+2=2x+12

step 1: subtract 2x from both sides.

4x+2−2x=2x+12−2x

2x+2=12

step 2: subtract 2 from both sides.

2x+2−2=12−2

2x=10

step 3: divide both sides by 2.

2x

2

=
