Why is it useful to rewrite a formula in terms of another variable?

1 answer:

6 0

Sometimes you are given one value and you have to find another value in a formula. For example if you're pouring a concrete sidewalk you'll need to know the length, width, and depth to calculate the volume of the concrete you'll have to buy. Another possibility is someone gives you concrete and you know the volume of it and you need to find out what size of a sidewalk you can make using the given volume of concrete.

kolezko [41]

Answer:

Now if the high and low monthly average temperatures satisfy the inequality, then the , monthly averages are always within 22 degrees of 43°F.

Step-by-step explanation:

The inequality describes the range of monthly average temperatures T in degrees Fahrenheit at a certain location.

The inequality expression is given as:

$|T-43|\leq 22$

now this expression could also be expressed as:

$-22\leq T-43\leq22\\\\-22+43 \leq T \leq 22+43\\\\21\leq T\leq 65$

Now if the high and low monthly average temperatures satisfy the inequality, then the , monthly averages are always within 22 degrees of 43°F.

( As the difference is 22 degrees to the left and right)
