You can't make it proper.You can only simplify.
Step 1: Factor both the numerator and denominator down to prime factors:62 = 2 * 31 
40 = 23 * 5Step 2: Calculate the greatest common factor, GCF (also called greatest common divisor, GCD), by taking all the common prime factors of the numerator and denominator, by the lowest powers:gcd(2 * 31; 23 * 5) = 2 
Step 3: Divide both the numerator and denominator by their greatest common factor, GCF (also called the greatest common divisor, GCD):62/40 =
(2 * 31)/(23 * 5) =
((2 * 31) : 2) / ((23 * 5) : 2) =
31/(22 * 5) =
31/20Step 4: Improper fraction, rewrite:31 : 20 = 1 and remainder = 11 => 
31/20 = (1 * 20 + 11) / 20 = 1 + 11/20 = 1 11/20 as a mixed number (also called mixed fraction).1 + 11 : 20 = 1.55 as a decimal number.

First you change 62/40 to a proper mixed number: 1 11/20

then you add 8 to 1 11/20 :

your final answer is 9 11/20

hope this helps :)

What is the inverse of [tex] x^{2} -2?

Mnenie [13.5K]

Assuming you want the inverse of f(x)=x²-2,

f(x)=x²-2
repalce f(x) with y
y=x²-2
switch x and y
x=y²-2
solve for y
x=y²-2
x+2=y²
√(x+2)=y
replace y with f⁻¹(x)
f⁻¹(x)=√(x+2)

the inverse is √(x+2)

A 168-cm tall person is 2 cm in Ming’s model. How high should his model swing be if the actual swing is 231 cm high?

serious [3.7K]

Answer:

The model swing should be 2.75 cm high.

Step-by-step explanation:

Given:

A 168-cm tall person is 2 cm in Ming’s model.

If the actual swing is 231 cm high.

Now, to find how high should his model swing be.

Let the model swing be $x\ cm.$

So, 168 cm tall person is equivalent to 2 cm.

Thus, 231 cm actual swing is equivalent to $x\ cm$ model swing.

Now, we get the height of the swing in the model by using cross multiplication method:

$\frac{168}{2} =\frac{231}{x}$

By cross multiplication:

⇒ $168x=462$

Dividing both sides by 168 we get:

⇒ $x=2.75\ cm.$

Therefore, the model swing should be 2.75 cm high.

What is the general process for solving an equation with one variable?

elena55 [62]

Greetings!

"What is the general process for solving an equation with one variable?"...

Typically when solving an equation with one variable, your objective is to isolate the variable on one side of the equation. This can be done adding/subtracting number to cancel them out on one side. You can also multiply/divide coefficients in order to isolate a variable.

Example:
 $2x+4=64$
Add -4 to both sides to isolate the variable.
 $(2x+4)+(-4)=(64)+(-4)$ 
Simplify.
 $2x=60$
Divide both sides by 2 to isolate the variable on one side.
$(2x)/2=(60)/2$
$x=30$

Hope this helps.
