1. can't be determined cause no info given on the rate of which the population is growing.
2. can't be determined/not true because the initial population of a could be less than b.
3. can't be determined/not true because we don't have enough info to tell how fast they grow and decline.
The answer is a because you fill in 4 where 2(x) is for the x
So here if a is -2 and b is 6 .
1. 6a -b =
Here you have to apply this method called substitution, the meaning is that you have exchange the variables with numbers given you above . So is going to be 6(-2) - 6 which is equal to -12 - 6, this the answer but if the question said find and solve the answers it will be -6
Answer:
27.3 dollars
Step-by-step explanation:
$72 To find out how much the sweater is without 20% off, you need to do this formula:
$60 x 20%
The answer is $12.
So, 20% of $60 is $12.
Now, you need to add 60 and 12 together to get the original sale price.
60 + 12
The answer is 72.
So the original price for the sweater is <span>72 dollars.</span>
