Ryan is performing an experiment. He starts with a solution that has a temperature of 12.2°C. He lowers the temperature 5 times

Anon25 [30]

Answer: The equation that can be used to find x, is given by

$-14.61^\circ C=12.2^\circ C-5x$

Step-by-step explanation:

Let the number of degrees he lowered the temperature by each time be 'x'.

Temperature he starts with = 12.2° C

Temperature he stopped with = -14.61° C

According to question, it is said that he lowers the temperature 5 times by the same amount each time.

So, it becomes,

$-14.61=12.2-5x\\\\-14.61-12.2=-5x\\\\-26.81=-5x\\\\\frac{26.81}{5}=x\\\\5.362^\circ C=x$

Hence, the equation that can be used to find x, is given by

$-14.61^\circ C=12.2^\circ C-5x$
