If you’re asking to solve a system of equations, then x=4 and y= 12/5 or 2.4

First Solve 2x+5y=20 for x

Add -5y to each side
2x=5y-20

Divide both sides by 2
x= -5/2y +10

Next substitute -5/2y +10 for y in the equation 6x-5y=12

6(-5/2y+10) -5y=12
-20y+ 60= 12

Then simplify again by adding -60 to each side
-20y= -48

Then divide by -20 on each side

Y= 12/5 (or 2.4)

Now to find x substitute 12/5 for y in x= -5/2y+10

X= -5/2(12/5) +10

X= 4

So X=4 and Y= 12/5 or 2.4

Hope that helped

The propeller blades on a submarine have a radius of 6 feet. At full speed, they turn at 120 revolutions per minute. What is the
bogdanovich [222]

Using proportions, it is found that the angular velocity at the tip of the blade is of 753.98 radians per minute.

<h3>What is a proportion?</h3>

A proportion is a fraction of a total amount, and the measures are related using a rule of three.

Each revolution has 2\pi radians, hence in one minute, the 120 revolutions will have a measure in radians of:

M = 120 x 2pi = 240pi = 753.98

Hence the angular velocity is of 753.98 radians per minute.
