Answer:
x = 29
Step-by-step explanation:
(x + 3) + (x - 1) + (x + 1) = 90
3x + 3 = 90
3x = 87
x = 29
Answer: A
Step-by-step explanation:It shows the correct graph
Answer:
2
Step-by-step explanation:
We take the equation
and substitute the values for each individual variable in the problem. It looks like this:
Now we can solve the equation.
When solved, it equals 2.
If there are two values places next to each other (E.g. xy), then the values are multiplied together. In this example, "3n - 2m" is one value as it is in the brackets. The second value is "2".
To simplify, you must open up the brackets. So multiply what is inside the brackets by what is outside. (2 x 3n) - (2 x 2m) = 6n - 4m
Answer:
B. The population is declining at a rate of 11.5%
Step-by-step explanation:
if your graph the equation you will clearly see that it is declining and if you don't know how to graph the equation then go to the demos calculator, its an app & website, super easy to use. most people would assume the answer would be one of the 88.5% just because it's in the original equation but the .885 in the equation doesn't represent the rate of change there for the answer is 11.5%.
