please explain how to use cancellation method with examples. I'm really confused...
Answers
Answer:
Cancellation it enables us to eliminate or get rid of one of the variables, so we can solve a more simplified equation.
Some textbooks refer to the elimination method as the addition method or the method of linear combination.
This is because we are going to combine two equations with addition!
Step 1
First, we align each equation so that like variables are organized into columns.
Step 2
Second, we eliminate a variable.
If the coefficients of one variable are opposites, you add the equations to eliminate a variable, and then solve.
If the coefficients are not opposites, then we multiply one or both equations by a number to create opposite coefficients, and then add the equations to eliminate a variable and solve.
Step 3
Thirdly, we substitute this value back into one of the original equations and solve for the other variable.
Example of how to apply the elimination method for solving systems of equations is attached.

do you need to regroup to subtract 881 from 4,986 how do u know?
Answers
no because
4986
881
4 1 0 5
there is no regrouping because every top number is equal to or larger than the bottom number
There is no need to regroup to subtract 881 from 4,986, the answer would be 4105.
What is an arithmetic operation?It is defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has basic four operators that is +, -, ×, and ÷.
It is given that:
The two numbers are:
881 and 4986
As we know,
The term PEDMAS describes the sequence in which arithmetic operations must be carried out in an equation.
According to this rule, operations should be carried out in the following order: parentheses, exponents, multiplication or division, then addition or subtraction.
After applying the concept of arithmetic operation:
= 4986 - 881
= 4105
Thus, there is no need to regroup to subtract 881 from 4,986, the answer would be 4105.

Find the value of x in the rational equation below. The answer must be an exact value.
(20)/(x^2-25)=(-3)/(5-x)
Thank You
Answers
x=5/3
alternative form
x=1/2/3, x=1.6
Since (20) = (-3) [we can cross multiply]
(x²- 25) (5-x)
⇒ (20)(5 - x) = (-3)(x² - 25) [expand the brackets]
⇒ 100 - 20x = -3x² + 75 [make the equation equal to zero]
⇒ 3x² - 20x + 25 = 0 [expand the middle term using
appropriate factors of the product
of the terms a and c (3 × 25)]
⇒ 3x² - 15x - 5x + 25 = 0 [factorize the terms]
⇒ (3x - 5 ) (x - 5) = 0 [using the knowledge that for the
produc to be 0, one of terms
must be zero]
⇒ (3x - 5 ) = 0 OR (x - 5) = 0 [solve for x in each case]
⇒ x = ⁵/₃ OR x = 5

find the sum of the first 10 term of geometric sequence 1,4,16,64...
with solutions
Answers
Answer:
Step-by-step explanation:
1 × 4 = 4
4 × 4 = 16
16 × 4 = 64
64 × 4 = 256
256 × 4 = 1024
1024 × 4 = 4096
4096 × 4 = 16384
16384 × 4 = 65536
65536 × 4 = 262144
so the sum of the first 10 term = 1 + 4 + 16 + 64 + 256 + 1024 + 4096 + 16384 + 65536 + 2622144 = 349525

Y=90
Explanation: Y is 90 because you can see that it is a right angle! To find X you can find the 3rd angle that is in the triangle with Y in it (which is 68) and then because X is supplementary to that angle we just found you can do 180-68 which is 112!
Answer:
x = 118°y = 84°Step-by-step explanation:
We observe that:
x = y + 22 as exterior angle of the triangle is the sum of non-adjacent interior angles.Also:
x = 118 as corresponding angles formed by two parallel lines and a common transversal.Find the value of y:
y = x - 22y = 118 - 22y = 84Solve the following equation:
