Answer:

x=5.2

Step-by-step explanation:

30-5x=4

First, subtract 30 from both sides of the equation

  • -5x=-26

Then divide by -5 to both sides of the equation

  • x=5.2

Checking your answer

  • 30-5(5.2)

an airplane is traveling at a constant speed of 600 miles per hour. How many feet does it travel in 10 seconds? Remember that 1
frez [133]
<h2>Hello!</h2>

The answer is:

The airplane will travel 8800 feet in 10 seconds.

<h2>Why?</h2>

It's a conversion exercise, we need to be careful in order to solve it with no mistakes.

First:

We need to remember that 1 hour is equal to 60 minutes, and 1 minute is equal to 60 seconds, so, to calculate how many seconds are in one hour, we need to perform the following operation:

Time=1hour*\frac{60minutes}{1hour}*\frac{60seconds}{nminute}=3600seconds

Second:

We need to convert from miles to feet, we need to remember that 1 mil is equal to 5280 feet.

So, solving we have:

Speed=600\frac{miles}{hour}*\frac{1hour}{3600seconds}*\frac{5280ft}{1mile}=880\frac{ft}{seconds}

Now, calculating how many feet does it travel in 10 seconds, we have:

distance=speed*time\\\\distance=880\frac{ft}{seconds}*10seconds=8800ft

We have that the airplane will travel 8800 feet in 10 seconds.

Have a nice day!

Solve the proportion 9/2 = 27/2y
dalvyx [7]

Answer:

y = 3

Step-by-step explanation:

We need to solve the below proportion in this problem,

\dfrac{9}{2}=\dfrac{27}{2y}

First of all, we cross multiply both sides such that,

9\times 2y=27\times 2\\\\18y=27\times 2

Dividing both sides by 18.

y=\dfrac{27\times 2}{18}\\\\y=3

For the above proportion, we find that the value of y is equal to 3.
