<span>The correct answer is: 21
Explanation:
Let's first assume few variables!
x = Ishann's age (in years)
y = Christopher's age (in years)
1. Ishann is 3 times as old as Christopher can be represented mathematically as:
x = 3y ---- (1)
2. Ishann is 14 years older than Christopher can be represented mathematically as:
x = y + 14 ---- (2)
Get the value of y from Equation (1) and plug it in Equation (2):
(2) => x = (x/3) + 14
3x = x + 42
2x = 42
x = 21
Hence Ishann is 21 years old!</span>
12 + n
if you substitute n for any whole number and simplify. you will find that 12+n does not equal any others. for example, i used 6 in place of n and all equations gives you 10 except 12+n
hope this helps!
Based on the fact that the divers went scuba diving, the divers in the order from the least to the greatest based on the liters left in their oxygen tanks is Dante, Sofia, Alexis.
<h3>Which diver has the least amount of oxygen?</h3><h3 />
To find out which diver has the least oxygen, you need to convert the fractions to decimals.
Alexis has seventy one ninths which means that they have the most oxygen left as this is much more than the rest.
Sofia has seven and five eights which in decimal is;
= 7 + 5/8
= 7.625 liters
This means that Sofia has more oxygen than Dante who has only 7.5 liters.
The order is:
Dante, Sofia, Alexis.
