Answer:
The integer would -3.
Step-by-step explanation:
Think of it this way:
The elevator goes +7 (Positive = Up) and then -4 (Negative = Down). What is 7-4? That's easy it's just 3. But since the floor level goes down, <u>it would be negative.</u> So you just make it -3.
Check your work:
If we went up from the 4th floor by three, we would get up to the 7th floor.
Hope it Helps!
Answer:
D
Step-by-step explanation:
Multiply both sides by 12 to get x+36<_84.
Then move the constant to the right to get x by itself: x<_84-36
Subtract 36 from 84 to get 48.
Now you're left with x<_48
btw <_ is less than or greater than i just don't know how to place the sign on top of the underscore :/ hope this helped :)
− 2 ± 2 i √ 2 I think that’s the answer
Markup means they added to the price
so find 20% and add that to 279
percent means parts out of 100
20%=20/100=2/10
'of' means multiply
20% of 270=
2/10 times 270=
54
20%=54
so we add that markup to original
270+54=324
nwe price=$324
