Khan academy how to solve equations with fractions and mixed numbers

1 answer:

8 0

Generally, you are told to approach these by "clearing fractions". That is, you generally multiply the equations by the least common denominator so all fractions and mixed numbers become integers.

Alternatively, you can simply do the arithmetic using the numbers given. You learned a long time ago how to add, subtract, multiply, and divide mixed numbers and fractions. Do these operations as necessary to solve the equations.

The quantity q varies inversely with the square of m and directly with the product of r and x. When q is 2.5, mis 4 and the

saveliy_v [14]

Answer:

The constant of proportionality is 5.

Step-by-step explanation:

If the quantity q varies inversely with the square of m and directly with the product of r and x, then the variation equation is

$q=k\frac{rx}{m^2}$

When q=2.5, m= 4 and the

product of rx = 8.

We plug in this values to get;

$2.5=k(\frac{8}{4^2})$

$2.5=k(\frac{8}{16})$

$2.5=\frac{1}{2}k$

Multiply both sides by 2

$k=2.5\times 2=5$

The constant of proportionality is 5.

Lines that meet or cross each other to form square corners are called ______.

Viefleur [7K]

The lines that intersect to form square corners that are right angles are called: C. perpendicular lines.

<h3>What are Perpendicular Lines?</h3>

Perpendicular lines are lines that intersect each other at a point and forms for square corners that are right angles at that point of intersection.

An example of perpendicular lines is shown in the image attached below.

Thus, the lines that meet to form right angles are called: C. perpendicular.
