Answer:

The number is 8.

Step-by-step explanation:

Rewrite the word problem as an equation.

The sum of (we will be adding.), half of a number (we can use x, this will be written as x/2.) and double the number (this will be written as 2x) is 20.

To find the number, solve the equation.

x/2 + 2x = 20

Multiply both sides by 2.

x + 4x = 40

Combine terms.

5x = 40

Divide both sides.

x = 8.

PLS HELP!!! The snowy tree cricket is sometimes called the temperature cricket because the frequency of its chirps varies based

trasher [3.6K]

Answer:

Step-by-step explanation:

62 degrees Fahrenheit

Step-by-step explanation:

The number of snowy tree cricket chirps per minute is 148 less than 4 times the outside temperature in degrees Fahrenheit.

Let x = number of chirps

f = temp in Fahrenheit

x = 4f -148

Now let x = 100

100 = 4f-148

Add 148 to each side

100+148 = 4f-148+148

248 = 4f

Divide each side by 4

248/4 = 4f/4

62=f
