Perform the operation. 4x-y/3 - x+y/2

Mathematics
1 answer:
Elanso [62]3 years ago

Answer:

5(x-y)/6

Step-by-step explanation:

(4x-y)/3 - (x+y)/2

We have to find the Least common multiple to simplify the operation.

(The Least common multiple of 3 and 2 = 3*2 = 6)

[2(4x-y)-3(x+y)]/6

(8x-2y-3x-3y)/6

5x-5y/6

5(x-y)/6

The rule of subtracting the fraction, including the constant, is to do in a simplification method.

Therefore, the answer is 5(x-y)/6

An altitude of a right triangle to its hypotenuse divides this hypotenuse into two segments that measure 9cm, and 16cm. What are
ozzi

Answer:

Step-by-step explanation:

Let a be the length of the altitude, then from the given triangles, applying the basic proportionality theorem,  we get

\frac{BD}{AD}=\frac{DC}{BD}

⇒(BD)^{2}=DC{\times}AD

⇒(BD)^2=9{\times}16

⇒BD=\sqrt{144}

⇒BD=12 cm

Thus, the length of altitude is: 12 cm.

Now, \frac{AB}{AD}=\frac{AC}{AB}

⇒(AB)^{2}=220

⇒AB= 14.83 cm

Also, \frac{BC}{DC}\frac{AC}{BC}

⇒(BC)^{2}=400

⇒BC=20 cm

Thus, the lengths of the legs of this triangle are 14.83 and 20 cm.

The graph represents the atmospheric pressure, in pounds per square inch, as a function of altitude in miles above sea level.
Veseljchak [2.6K]

From the graph, we can actually see that as the altitude increase, the value of the pressure decreases. Or if we say it the opposite way, as the altitude decreases (approaches sea level), the pressure increases, therefore the answer is:

 

As the altitude approaches sea level, the atmospheric pressure increases.
