Question

Answer the following questions CORRECTLY I will know if this is wrong. I WILL REPORT ANY INCORRECT ANSWERS!

Answer 1

Answer by JKismyhusbandbae:

a. The variable is t because it is asking for the temperatures for tomorrow.

B. |93 - t| < 10

It is this equation because we are looking for t and the temperature has to be below ten degrees it is today.

C. 93 - t < 10 and 93 - t

Answer 2

difference between a and b is |a-b|

difference between today and tomorrow is |today-tomorrow|

a. if we say t=tomorrow, then

b. difference is less than 10, so |93-t|<10 is the expression

c. for |a|<b, solve -b<a<b

|93-t|<10

-10<93-t<10

minus 93 from everybody

-103<-t<-83

divide both sides by -1 and flip sign direction

103>t>83

83<t<103 is the solution, which is the range of tempuratures allowed

in set notation, the range of values of tempuratures for which she is allowed to play outside is {t | 83<t<103}
