I don't understand the question you are asking sorry.
1x + 8 = 10 + 0.5x
1x - 0.5x = .5x
.5x + 8 = 10
10 - 8 = 2
2/.5 = 4
Therefore, it will take 4 years for the two trees to have grown to the same height.
30,000 - 19,500 = 10,500 gallons left to fill the pool. So I am assuming the answer would be w = 10,500 gallons... unless there was an equation missing in the question
Answer: There are 19 classes
Step-by-step explanation:
divide the total amount amount of students by the amount of students in each class
Answer:
x = -5/2 + i√19 and x = -5/2 - i√19
Step-by-step explanation:
Next time, please share the possible answer choices.
Here we can actually find the roots, using the quadratic formula or some other approach.
a = 1, b = 5 and c = 11. Then the discriminant is b^2-4ac, or 5^2-4(1)(11). Since the discriminant is negative, the roots are complex. The discriminant value is 25-44, or -19.
Thus, the roots of the given poly are:
-5 plus or minus i√19
x = -----------------------------------
2(1)
or x = -5/2 + i√19 and x = -5/2 - i√19
