OpenStudy (cj49):

so wats the actual question in this

OpenStudy (anonymous):

it just says

OpenStudy (cj49):

OpenStudy (anonymous):

lol what would i write on my paper?

OpenStudy (cj49):

wat are the options

OpenStudy (anonymous):

theres none :( my teacher wants me to show my work

OpenStudy (cj49):

here we have two situtations..one is the monthly avg temp in winter and one of summer so the intergers that wud correspond to the situation wud be -59 amd 57 if u convert them to celcius then it wud be foh -59 its -50 degree Celsius and foh 57 its 13.889 Celsius

OpenStudy (anonymous):

do you know how to do this one?

OpenStudy (cj49):

ok so wat u need to find in this

OpenStudy (anonymous):

its the same question but different problem

OpenStudy (anonymous):

tell which intergers correspond to the situation

OpenStudy (cj49):

idk if this makes any sense but she intercepted a missle worth +20pts lost her starship worth -15Opts captured a base worth +300pts so 20-150+300=170 pts

OpenStudy (anonymous):

this is so confusing lol

OpenStudy (anonymous):

do you know how to do this?

OpenStudy (cj49):

she lost her base so it wud be minus 150 she intercepted a missle so add 20 an she captured a base so add 300pts total: 300-150+20=170pts

OpenStudy (cj49):

just change the sign for eg -1 wud be 1 or 5 wud be -5 and 0 wud remain 0

OpenStudy (anonymous):

so if its -21 change it to 21?

OpenStudy (cj49):

yes

OpenStudy (anonymous):

oh ok thank u

OpenStudy (cj49):

OpenStudy (anonymous):

I've been on this question for an hr

OpenStudy (cj49):

lol is it 7x or does it mean 7(10-3)^2

OpenStudy (anonymous):

7times(10-3)^2 lol

OpenStudy (anonymous):

its a multiply sigh

OpenStudy (anonymous):

are we going thru pemdas ?

OpenStudy (cj49):

yes

OpenStudy (anonymous):

im stuck on the -2(3+1)^2

OpenStudy (cj49):

sorry instead of -7 it wud be -8^2 i.e 64

OpenStudy (anonymous):

so is the answer of this whole problem 325?

OpenStudy (cj49):
