Answer:
h = 84
Step-by-step explanation:
3 = 87 - h
h + 3 = 87 (Add h to both sides)
h = 84 (Subtract 3 from both sides)
Answer: D
154 miles.
Step-by-step explanation:
Half way is 440/2 = 220. Subtract the 66 miles already traveled, and they have 154 miles to go.
At the start pizza has -6
the temperature rises 13 during the transport, so it should have -6+13=7
because the temperature goes down 19 when pizza is put in the home freezer, the final temperature should be 7-19=-12
so b is the correct answer
if the temperature rises -> +
if the temperature goes down -> -
8.2 because you would multiply 0.5 by 16.4 which equals 8.2
Since you cannot add numbers which have x to the power of something and normal x, A and B are incorrect. C is also incorrect because I don't even know how you could get that number.
D is correct.
(14x2 + 7x) + 9x2 - you don't even need the brackets, so
14x2 + 7x + 9x2
(14x2 + 9x2) + 7x
23x2 + 7x
