Well you will need two number that are divisible by 30 and add up to -7 so they will have to be a negative.

I would try -2 and -5 which are both divisible by 30 and ad up to -7 so...

-2/30 + -5/30 = -7/30

two factors are multiplied and their product is 34.44 one factor is a whole number.how many decimal places are in the other fact

Jobisdone [24]

Well, if the product has two decimal places and it is known that one factor has none, then the other factor must have two decimal places. Where would those two decimal places in the product come from otherwise?

Some examples:
1 * 34.44 = 34.44
2 * 17.22 = 34.44

In both cases, the non-integer factor had two decimal places.

Hope I helped, and let me know if you have any questions! :D

Good evening

The absolute value has the following property:

$|x|\leq a\iff -a\leq x\leq a$

Apllying:

$|T-55| \leq 10 \iff -10\leq T - 55 \leq 10\\ \\ -10 + 55 \leq T -55 + 55 \leq 10 + 55\\ \\ \boxed{45\leq T \leq 65}$

The average temperature range is between 45 and 65 degrees.
