a train is traveling at 30 miles per hour. how long will it take the train to travel 180 miles? 1.210 hours 2.150 hours 3.6 hour

FinnZ [79.3K]

None of these are correct. the answer is 6 hours, because if the the train is traveling at 30m/h and the distance = 180m than your equation is 30m/180

Step-by-step explanation:

Step 1: Define

-9x + 1 = -x + 17

Step 2: Solve for x

Add 9x on both sides: 1 = 8x + 17
Subtract 17 on both sides: -16 = 8x
Divide 8 on both sides: -2 = x
Rewrite: x = -2

Square root of 144 X^7 Y^5

LekaFEV [45]

The first step to solving this is to factor out the first perfect square
$\sqrt{12^{2} x^{7} y^{5} }$
now factor out the second perfect square
$\sqrt{ 12^{2} x^{6} X x y^{5} }$
then factor out the second perfect square
$\sqrt{ 12^{2} x^{6} X x y^{4} X y}$
the root of a product is equal to the product of the roots of each factor
$\sqrt{ 12^{2} }$ $\sqrt{ x^{6} }$ $\sqrt{ y^{4} }$ $\sqrt{xy}$
reduce the index of the radical and exponent with 2 of the first square root
12 $\sqrt{ x^{6} }$ $\sqrt{ y^{4} }$ $\sqrt{xy}$
reduce the index of the radical and exponent with 2 of the second square root
12x³ $\sqrt{ y^{4} }$ $\sqrt{xy}$
reduce the index of the radical and exponent with 2 of the third square root
12x³y² $\sqrt{xy}$
this means that the correct answer to your question is 12x³y² $\sqrt{xy}$ .
let me know if you have any further questions
