Answer:
x = -3/89
Step-by-step explanation:
C=A+B
C₄₁= row=4; column=1
C₄₁=A₄₁+B₄₁
=2(7)-3(4)
=14-12
=2
Answer: C₄₁=2
Answer:
1/4
Step-by-step explanation:
Five bottles of sunscreen were shared equally among 20 campers. What fraction of a bottle for each camper use?
This question above is calculated as:
Number of bottles of sunscreen/Number of campers
= 5/20
= 1/4
Hence, fraction of a bottle for each camper use is 1/4
The answer is 12.
Steps
If that number is x
(3+x)/(8+x)=3/4
"Cross multply"
4(3+x)=3(8+x)
12+4x=24+3x
x=12
To check: add 12 to 3 and 8. 3+12=15 and 8+12=20. 15/20=3/4
Not all 30-story buildings are the same height. Depends on how tall the ceiling is on each floor. But usually it is around 300 feet
