Answer:
x is the missing side (x > 0)
because this is a right triangle, using Pythago theorem, we have:
x² + 4² = 12²
⇔ x² = 12² - 4²
⇔ x² = 128
=> x ≈ 11.3
Step-by-step explanation:
Answer:
x = 2
Step-by-step explanation:
<h2>Simplifying expressions:</h2>
5x - 7 - 5(7x - 12) + 7 = 0
Distribute (-5) to each term of (7x - 12)
5x - 7 + 7x*(-5) + (-12)*(-5) + 7 = 0
5x - 7 - 35x + 60 + 7 = 0
5x - 35x - 7 + 60 +7 = 0
Combine like terms.
-30x + 60 = 0
Subtract 60 from both sides
-30x = -60
Divide both sides by (-30)
x = (-60)/(-30)
x = 2
Answer:
9 steps
Step-by-step explanation:
Let 
be the number of jumps
and 
be the number of steps
So the first case
Second case
Both cover equal distances so
So, one jumps is 9 steps.
First, you have to do 480/32. (divide) That gives you the cost of $15 per person.
