Which of the following statements are true of solving equations?

Mathematics

kherson [118]3 years ago

The statement A, B and C are true for solving the equations.

Further explanation:

Given:

The statements of solving equation are as follows,

A. You are using inverse operations to isolate the variable.

B. The addition property is usually used first.

C. You are making a good guess at the solution.

D. Order of operations is often done in reverse order.

E. There are usually two solutions for a linear equation.

Explanation:

By isolate the variables we can solve the linear equation.

Consider an equation as y + 3 = 5.

To solve the equation isolate y.

\begin{aligned}y&= 5 - 3\\&=2\\\end{aligned}

Option A is true.

Now consider the two equations as a - 3b = 4 and a + 3b = 8.

We have to add the two equations to solve the equations.

 \begin{aligned}a - 3b + a + 3b&= 4 + 8\\2a&=12\\a&=\frac{{12}}{2}\\a&= 6\\\end{aligned}

Option B is true.

Option C is false as we cannot solve the equation by guessing the solution.

Option D is true as we can often reverse the order of the operation.

Option E is false as the linear equation can have exactly one solution or infinitely many solutions.

Hence, the statement A, B and C are true for solving the equations

we will check each options

option-A:

For solving any equations , we always isolate variables on anyone side

For exp: x+7=1

so, this is TRUE

option-B:

For solving system of equations

For exp:

x-y=1

x+y=3

If we use addition , we could easily solve for x and y

so, this is TRUE

option-C:

We always solve problems using conventional method

we do not guess

so, this is  FALSE

option-D:

We often reverse order of operation

For exp:

(x-2)^2-3=0

so, this is TRUE

option-E:

For linear equations , we always get one solution , infinite solutions or no solutions

so, this is FALSE

Merlin wants to make more money selling fake beards this month than he did last month. All black beards in his shop cost the sam
sukhopar [10]

We know that all black beards cost the same money

And all red beards cost $25

And B represents number of black beards

And R represents number of red beards

We have been given the inequality 20B+25R > 350 to show the target for this month.

The above inequality shows that Merlin needs to make more than 350, hence he made 350 last month

Further, it shows that B has been multiplied by 20, hence the black beard's cost was 20

When deriving the quadratic formula by completing the square, what expression can be added to both sides of the equation to crea
nignag [31]

The expression that would be added to both sides is (b/2a)^2

<h3>How to determine the expression?</h3>

The equation is given as:

x^2 + b/ax + __ = c/a + __

Take the coefficient of x

b/a

Divide by 2

b/2a

Square the expression

(b/2a)^2

Hence, the expression that would be added to both sides is (b/2a)^2

Barb is making a bead necklace. She strings 1 white bead,then 3 blue beads,then 1 white bead,and so on. Write the numbers for th
nataly862011 [7]

The numbers for the first eight beads that are white are; 1, 5, 9, 13, 17, 21, 25, 29

<h3>Arithmetic Sequence</h3>

We are told that she strings in this order;

  • 1 white
  • 3 blue
  • 1 white bead

Now, after the first white bead, the next white bead is the 5th bead in total.

This means the difference in interval between white beads is; 5 - 1 = 4 beads

Thus, the numbers for the first eight beads that are white are;

1, (1 + 4), (1 + 4 + 4), (1 + 4 + 4 + 4).....

Thus, we have;

1, 5, 9, 13, 17, 21, 25, 29
