Answer:

Step-by-step explanation:

-2.1 + 0.3 - 1.7 - 0.4 = -3.9
answer
A. -3.9 lbs
The situation forms the right triangle above:
Where x is the length of the ladder.
Apply the Pythagorean theorem:
c^2 = a^2 +b^1
where:
c = hypotenuse = longest side = x
A &b = the other 2 legs of the triangle
Replacing:
x^2 = 60^2 + 15^2
Solve for x
x^2 = 3,600 + 225
x^2 = 3,825
x =√3,825
x = 61.85 ft
Answer:
Exact: 16.6
Rounded: 17
Step-by-step explanation:
1 coach = 50 people (50 / 1 = 50 people)
2 coaches = 100 people (100 / 2 = 50 people)
x coaches = 830 people (830 / x = 50 people)
830 / x = 50
mutely both sides by x
830 / x * x = 50 * x
830 = 50x
divided both sides by 50 to get x alone
830 / 50 = 50x / 50
830/50 = x
