Answer:
By plotting in the number in the equation (aka where all the x’s are variables are) and seeing if it works.
Step-by-step explanation:
For example, let’s use the problem:
3x + 4 = 16
if the given number is 4, we fill it in for x-
3 (4) + 4= 16
solve to see if true:
12 + 4 = 16
16 = 16
hence, the given number 4 makes the equation true!
hopes this helps, have a great day :)
Answer: The equivalent expression is:
new price = s*0.8
Step-by-step explanation:
When the original price of something is A, and we have X% off, the new price if that object will be:
New price = A - (X%/100%)*A
Like in this case, the original price is s, and the discount is 20%
Then the new price can be written as:
new price = s - (20%/100%)*s = s - 0.2*s = s*(1 - 0.2) = s*0.8
This is the equivalent expression we wanted to get.

Answer:
The correct expression to calculate the number of bees after t days if the initial swarm had 1000 bees is
Step-by-step explanation:
Given -
The population of a swarm of killer bees increases by 10 times in 50 days
The rate of increase of population is per day
As we now the equation of population projection is
Where P0 = initial population
P is the population after time t
and r is the rate of increase of population
Substituting the given values in above equation, we get -
