Please help the temperature in degrees fahrenheit can be estimated by counting the number of times a cricket chirps in one minute write an algebraic expression for the following written expression the number of chirps divided by 4 added to 37

Answers

We have been given that the temperature in degrees Fahrenheit can be estimated by counting the number of times a cricket chirps in one minute.

Let us start with assuming the number of chirps as x.

We are supposed to write an algebraic expression for the number of chirps divided by 4 added to 37.

Let us first write an algebraic expression for number of chirps divided by 4. The algebraic expression for this will be .

Let us now write an algebraic expression for number of chirps divided by 4 added to 37. The algebraic expression for this will be .

Therefore, the required algebraic expression is .

X/4 + 37, where x is the number of chirps.

Use the guess-and-check method to solve the equation:40x = 30(x + 2)

Answers

Don't know why they'd encourage a "guess-and-check" method.

But let's play their game.

Choose x=2 (I just invented it):    Is 40(2) = 30(2+2)?  Is 80 = 120?  No.

Try x=1, x=3, etc.

Better yet, do the problem algebraically:  40x = 30x + 60, or 10x = 60.
Then x=6.      Check:  Is 40(6) = 30(6+2)?  Is 240 = 30(8)?  YES.

Answer:  x=6
