18. You are standing beside the Colorado River, 400 feet

Veseljchak [2.6K]

<h3>Answer: B. 781.6 feet approximately</h3>

=======================================================

Work Shown:

The horizontal portion is 400+166 = 566 feet. Label this as 'a', so a = 566. The vertical side is unknown, so b = x. The hypotenuse is c = 965

Use the pythagorean theorem

a^2+b^2 = c^2

566^2+x^2 = 965^2

x^2 = 965^2 - 566^2

x = sqrt( 965^2 - 566^2 )

x = 781.58108984289 which is approximate

x = 781.6 feet when rounding to one decimal place

What is the solution for 2y=x+2 x-3y=-5

Mars2501 [29]

Answer:

x = 4

y = 3

Step-by-step explanation:

Given equations :-

2y = x + 2
x - 3y = -5

Second equation can be written as ,

x - 3y = -5
-3y = -x - 5

Adding them :-

-3y + 2y = 2 -5
-y = -3
y = 3

Put this in (ii) :-

x = 3y - 5
x = 3*3 - 5
x = 9 -5
X = 4
