Answer: If you're looking for the value of x, it's 1.
Step-by-step explanation:
Add the numbers. x-10-2x+7=8+x-10-3x--->x-3-2x=8+x-10-3x
Combine like terms. x-3-2x=8+x-10-3x ---> -x-3=8+x-10-3x
Subtract the numbers.-x-3=8+x-10-3x---> -x-3=-2+x-3x
Combine like terms. -x-3=-2+-3x---> -x-3=-2-2x
Rearrange terms. -x-3=-2-2x---> -x-3=-2x-2

Answer:
The estimated size of the population in 10 days is of 1372 mosquitos.
Step-by-step explanation:
Population after t days:
The population after t days is given by:
In which P(0) is the initial population and r is the growth rate, as a decimal.
P(0)=574.
So
P'(0)=50
Since P'(0)=50
So
Estimate the size of the population in 10 days
This is P(10).
The estimated size of the population in 10 days is of 1372 mosquitos.
<span>A zero pair is created when a pair of numbers, one positive and the other negative, equals a sum of zero.The main purpose of a zero pair is to simplify the process of addition and subtraction in complex mathematical equations featuring multiple numbers and variables. For example, in the problem 2+6-3-2, the positive 2 and the negative 2 cancel each other out because they are a zero pair, thus reducing the problem to 6-3.
Examples of Zero Pair:
-9 + 9 = 0</span>
