Answer:

Hey Dude ok so it's g = 7 Have a nice day!

Step-by-step explanation:Simplifying

-2 = g + -9

Reorder the terms:

-2 = -9 + g

Solving

-2 = -9 + g

Solving for variable 'g'.

Move all terms containing g to the left, all other terms to the right.

Add '-1g' to each side of the equation.

-2 + -1g = -9 + g + -1g

Combine like terms: g + -1g = 0

-2 + -1g = -9 + 0

-2 + -1g = -9

Add '2' to each side of the equation.

-2 + 2 + -1g = -9 + 2

Combine like terms: -2 + 2 = 0

0 + -1g = -9 + 2

-1g = -9 + 2

Combine like terms: -9 + 2 = -7

-1g = -7

Divide each side by '-1'.

g = 7

Simplifying

g = 7

Answer:

g=7

Step-by-step explanation: You have to first get the variable alone. So, you would add 9 since it is on the side of the variable, and you add because you do the opposite of what is being done. You would do this on both sides, therefore the answer is 7.

Solve: x^+4/x-1 = 5/x-1
AlexFokin [52]
The first step for solving this equation is to determine the defined range.
\frac{ x^{4}  }{x-1} = \frac{5}{x-1}, x ≠ 1
Remember that when the denominators of both fractions are the same,, you need to set the numerators equal. This will look like the following:
x^{4} = 5
Take the root of both sides of the equation and remember to use both positive and negative roots.
x +/- \sqrt[4]{5}
Separate the solutions.
x = \sqrt[4]{5}           , x ≠ 1
x = -\sqrt[4]{5} 
Check if the solution is in the defined range.
x = \sqrt[4]{5} 
x = -\sqrt[4]{5} 
This means that the final solution to your question are the following:
x = \sqrt[4]{5}          
x = -\sqrt[4]{5} 
Let me know if you have any further questions.

The difference of two rational numbers is always negative true of false
Vlada [557]

Comparing two rational numbers

Use fraction form:

 

Make the denominators the same and compare the numerators. The number with the smaller numerator is smaller. For example, to compare a/b and c/d, we rewrite

 

a/b=a*d/b*d

  = ad/bd and c/d = c*b/d*b=bc/bd

 

Now just compare the numerators : "ad" and "bc"

 

Multiplying and Dividing Rational Numbers 

 

Multiplying and dividing rational numbers in decimal form is the same as multiplying and dividing integers. The decimal place of the product is the same of all decimals of all multiplied numbers. For example, 3.12*2.4.

 

Solution => 3.12*2.4=7.488

 

When multiplying or dividing rational numbers in fractional form, you multiply the numerators (N*N) and then multiply the denominators (D*D).

 

When dividing rational numbers in fractional form, first take the reciprocal of the divisor, and then multiply the numerators and the denominators.

 

Example => 5/9 divided by 2/7 .

 

Solution => 5/9 * 7/2 =  35/18

 

 

Adding Rational numbers

 

Adding and Subtracting rational numbers in decimal form is the same as adding and subtracting integers.

 

Example => -3.54+2.79=-0.75

 

When adding or subtracting rational numbers in fractional form, first make the denominator equal, and then add or subtract the numerators.  

The difference can be negative or positive.

Answer:

x = 7.5

Step-by-step explanation:

10/4 = 2.5

x = 3 × 2.5 = 7.5

Another way

x = 3/4 × 10 = 7.5
