Question

1)At 1 p.m., Lin records an outside temperature of –14.8°F. At 3 p.m... she records the outside temperature and notices the temperature had increased by 22.6 degrees.
What was the temperature that she recorded at 3 p.m.? ( no multiple choice) *confused on this question*

2) (x - 16) + 5 = -15
This is not multiple choice but my answer is -11


3) 5 = –(–z + 3)

–8 *my answer*

8
-2

2



4) The temperature at the summit of Mt. Mansfield dropped 17°F between 4 p.m. and 11 p.m. The temperature at 11 p.m. was –11°F. What was the temperature at 4 p.m.?

17 – t = –11 *my answer*

t – 17 = –11

11 – 17 = t

17 + 11 = t
Thanks I was kinda confused on one or two

Answer 1

#1
-14.8 + 22.6 = 7.8

#2
(x - 16) + 5 = -15
x-16+5 = -15
x-11 = -15
x = -4

#3
5 = –(–z + 3)
5 = z-3
8 = z

#4
t - 17 = -11
Your choice is the situation where the temperature started at 17° and then decreased by t°.
