Answer:
The percent increase of the population of chipmunks was 29%
Step-by-step explanation:
we know that
The population of 300,000 chipmunks represent the 100%
The increase of population is equal to
(387,000-300,000)=87,000 chipmunks
Using proportion find the percent increase
Let
x-----> the percent increase
300,000/100%=87,000/x
x=100*87,000/300,000
x=29%
Answer: I'm late but do you still need the answer
Step-by-step explanation:
Answer:
His test IS a solution.
Step-by-step explanation:
Both LHS and RHS are equal so it is a solution.
The given expression is :
2xx+3-5(x-2)
We know that, 
Aleena expands 2xx+3-5(x-2) as 2x²+3-5x-10. She is mistaken because the sign before 10 should be +10 instead of -10. Hence, the correct expanded form is 2x²+3-5x+10. Hence, this is the required solution.
