Answer:
B. 30
Step-by-step explanation:
The given angles are vertical angles because they are opposite angles created by the same two lines. This means that their value is equal. Let's set up an equation.
85 = 3x - 5
We need to solve for x.
First, combine like terms by adding 5 to both sides.
90 = 3x
Now we want to isolate x by dividing both sides by 3.
x = 30
This is your answer.
Let's check our work by plugging x back into our equation.
85 = 3x - 5
85 = 3(30) - 5
85 = 90 - 5
85 = 85
Your answer is correct.
Hope this helps!
Answer:
21 years
Step-by-step explanation:
Use the equation
where x is the number of years passed.
Once you've solved for it, x=20.475319. Although it's closer to 20 years to the nearest year, it's 21 years since you'll wont reach 3000 in year 20.
Answer:
