PART A
alligators:
x = total number of alligators
n = number of years
x=20*1.25^n
crocodiles:
y = total number of crocodiles
n = number of years
y=25+10n
PART B
alligators
x=20*1.25^4 = 48.82 round up to 49
crocodiles 25 +10(2) = 25+20 = 45
Part C
7 years
20(1.25^n)=25+10n
1.25^n=1.25+0.5n
n=7
check:
alligators 20+1.25^7 = 95.36
crocodiles = 25+10(7) = 95
Answer:
Simple
65 miles per hour on average
Step-by-step explanation:
You add 60 to 70 and then you divide them by 2
Which is
60 + 70 = 130
130 ÷ 2 = 65
Infinity many solutions because they both equal the same when the problem is solved.
In the number 4,586,909, the 6 is in the 4th place to the left of the decimal point which is the thousands place.
For a six to be 100 times more than in the thousands place, it must be in the hundred-thousands place. That is the 6th place to the left of the decimal point.
The answers are B. and D.
