Answer:

<h2>x = 140, y = 80</h2>

Step-by-step explanation:

$\left\{\begin{array}{ccc}x=-2y+300&(1)\\3y=800-4x&(2)\end{array}\right\\\\\text{Substitute (1) to (2):}\\\\3y=800-4(-2y+300)\qquad\text{use the distributive property:}\ a(b+c)=ab+ac\\\\3y=800+(-4)(-2y)+(-4)(300)\\\\3y=800+8y-1200\\\\3y=8y-400\qquad\text{subtract}\ 8y\ \text{from both sides}\\\\-5y=-400\qquad\text{divide both sides by (-5)}\\\\y=80\\\\\text{Put it to (1):}\\\\x=-2(80)+300\\\\x=-160+300\\\\x=140$

Find x round to the nearest tenth! please help!!! more trigonometry!

hoa [83]

Answer:

<h2>x = 437.3 ft</h2>

Step-by-step explanation:

Look at the picture.

Use cosine:

$cosine=\dfrac{adjacent}{hypotenuse}$

We have a measure of the angle and length of the hypotenuse:

$\alpha=29^o,\ hypotenuse=500\ ft$

$\cos29^o\approx0.87461$

Substitute:

$\dfrac{y}{500}=0.87461$ <em>multiply both sides by 500</em>

$y=437.305\to y\approx437.3$
