I am joyous to assist you anytime.
-30-5x=-4x-6(5+4x)
First, you need to use the distributive property on the right to get -30-5x=-4x-30-24x
Then, you can add like terms to get -30-5x=-30-28x
Then, you can add 30 to both sides and add 5x to both sides to get 0=-23x
Finally, you divide both sides by -23 to get 0=x
Answer:
x = 2
Step-by-step explanation:
All the red lines tell you that each side must be equivalent because the angles are aka equilateral triangle.
So, 2x+4 = 8
2x = 8-4
2x = 4
2x/2 = 4/2
x = 2
Answer:
1 year
Step-by-step explanation:
The population can be modelled by the equation:
From the question, the initial population is
The annual growth rate is r=0.04
We want to find how long it will take for that population to reach 43500.
We substitute the values to get:
To the nearest year, t= year
