Answer:
7x4=28
28/8=3.5 <em>(you cant get 3.5 pizzas so ROUND UP)</em>
SO you need 4 pizzas
First we need to replace x with -2:
24/(3*-2=-6)-2
24/4=6
6 is the answer
7- 5n=6+6(n+2)
7- 5n=6+6n+12
7 -5n=18+6n
5n-6n=18-7
-11n=11
n=-1
The answer is 71 because it has to add up to 180
Answer:
It will take ≈5 hours (5.278)
Step-by-step explanation:
First we need to find how many number she counts in one hour. We know she counts 60 every one minute and there are 60 minutes in an hour. 60x60=3600
Now we divide 19,000 by 3600 to find how many hours it will take
19000/3600=5.278
It will take ≈5 hours (5.278)
