Answer:


Step-by-step explanation:

9y + 12 = 4y - 10

Sub. 4y from both sides

5y + 12 = 10

Sub. 12 from both sides

5y = -2

Divide 5from both sides

y = -2/5

An airplane travels at 150 miles per hour. The total distance traveled is 637.5 miles. Which equation should be solved to determ
OverLord2011 [107]
The distance (d) traveled by the airplane is the product of multiplying the speed (s) and the trip took (h). The equation is shown below, 
                                           d = s x h
Substitute the known values to the equation, 
                                       637.5 miles = (150 mile/ hour) x h
Manipulating the equation,
                                       h = (637.5 miles) / (150 mile/ hr) 
h is equal to 4.25 hours.

Solve the triangle.<br><br> a = 10, b = 23, C = 95°
gayaneshka [121]
C² = a² + b² - (2ab * cosC) 
<span>c² = 10² + 23² - (2 * 10 * 23 * cos95) </span>
<span>c² = 100 + 529 - (460 * -.08715) </span>
<span>c² = 629 - (-40.1) </span>
<span>c² = 669.1 </span>
<span>c = 25.87 </span>

<span>(Sin C) / C = (Sin A) / A </span>
<span>(Sin 95) / 25.87 = SinA / 10, Remember 0 < A < 85 </span>
<span>(10 * Sin95) / 25.87 = Sin A </span>
<span>A = arcsin ((10 * sin95) / 25.87) </span>
<span>A = 22.65º </span>

<span>B = 180 - A - C </span>
<span>B = 180 - 95 - 22.65 </span>
<span>B = 62.35º </span>

<span>I hope this helps. Have a good day.</span>
