Exponential would be the correct answer I believe...
1) 2 1/3 is also equal to 7/3
4 1/5 is also equal to 21/5
you need to make the denominators the same so you have to find the lowest common multiple, which is 15 since both 5 and 3 can be times by to make 15
you need to also times the numerators by the number you're timesing the denominator by
7/3 x 5 = 35/15
21/5 x 3 = 63/15
now add those together
35/15 + 63/15 = 98/15
now just convert 98/15 back to a mixed fraction
98/15 = 6 8/15
the answer is..

I'll do the others in a different answer!!

Answer:
-48 and -49
Step-by-step explanation:
n + n + 1 = -97
2n + 1 = -97
2n + 1 - 1 = -97 - 1
2n = -98
2n/2 = -98/2
n = -49
-49 + 1 = -48
-49, -48
Answer:
Last week the coral reef grew .0196m
Step-by-step explanation:
So it's hard to explain but simply Milli witch is the symbol "m" is a unit prefix in the metric system denoting a factor of one thousandth (10 −3). So 19.6mm is 19.6*10^-3m. in other words 19.6 times 10^-3m
hope this helps sorry it's so complicated :/
