18+5= n
n= 23
D. 23
15+5=20 so u just gotta add 5 to 18
( -6) - ((-2) - 5) × 2
First, simplify your brackets. / Your problem should look like:
Second, simplify -2 - 5 to get -7. / Your problem should look like:
Third, multiply 7 × 2 to get 14. / Your problem should look like:
Fourth, simplify. / Your problem should look like:

Answer:
8
To calculate this probability is often easier to calculate the complement
the prob that we are looking for is 1-P(No salt packed in dinner)
Note: No salt packed with dinner is the complement event of having salt packed within
so let's find this probability
He is what we know
if John packs 4/45 chance no salt included
if Sue packs 3/70 chance no salt
if Marry packs 2/25 No salt
We are looking into probability is the sum (note these events are disjoint)
final result should be 1- that sum
Answer:
1. Positive numbers are delivered cups and negative numbers are used cups.
2. There are 2,329 cups left
3. There were used 281 cups
Step-by-step explanation:
2. 1719 - 356 - 782 = 581
3. 2000 - 1719 = 281
Answer:
m=n+p
Step-by-step explanation:
(180-m)+n+p=180
180+n+p-180=m
m=n+p
