2.5(t - 2) - 6 = 9
2.5(t - 2) = 9 + 6 = 15
t - 2 = 15/2.5 = 150/25 = 6
t = 6 + 2 = 8
Answer: 8
Check: 2.5(8 - 2) - 6 = 2.5(6) - 6 = 1.5(6) = 9 good
Answer:
About 7 hours per person
Step-by-step explanation:
412 divided by 60 because there are 60 minutes in an hour.
6.8667 which is about 7 hours.
The given expression is
We extract the common factor 2x.
The first solution is 0.
Now, we solve the quadratic expression. We have to find two numbers whose product 20 and whose difference is 8. Those numbers are 10 and 2.
<h2>Hence, the given expressions expressed, as factors, is</h2>
Using the Pythagorean Theorem a^2 + b^2 = C^2
a and b are the sides and C is the Hypotenuse.
The picture you have sides of a and 15 and the hypotenuse is 17
The formula becomes a^2 + 15^2 = 17^2
