a. 3x - 3 > 6
b. 24x + 4 < 52
c. -2x - 2 < 8
d. 10x - 100 > 0

Answers

Answer 1

Answer:

[tex]3x - 3 > 6\\= 3x - 3\\=0x\\0x < 6\\\\24x + 4 = 28x\\28x < 52\\\\-2x - 2 < 8\\= -2x - 2\\= -4x\\-4x < 8\\\\10x - 100 > 0\\= 10x - 100 \\=-90x\\-90x > 0[/tex]<---- Why is -90x greater than 0?

because 90x > 0.

Step-by-step explanation:

hope this helped.

Answer 2

Answer:

a. = x > 3

b. = x < 2

c. = x > -5

d. = x > 10

Step-by-step explanation:

Solve means to find x.

a.

3x - 3 > 6

+3 each side

3x > 9

Divide by 3 each side

x > 3

b.

24x + 4 < 52

-4 each side

24x < 48

Divide by 24 each side

x < 2

c.

-2x - 2 < 8

+2 each side

-2x < 10

Divide by -2 each side (Causing the inequality sign to flip, dividing or multiplying by a  negative causes it to.)

x > -5

d.

10x - 100 > 0

+100 each side

10x > 100

Divide by 10 each side

x > 10

Write an absolute value equation to satisfy the given solution set shown on a number line.

<————•—————————-•——————->
-1/2 1/2 a

Thanks!

Answers

/1/2/ sorry I don’t know how to do the straight line

An absolute value equation to satisfy the given solution set shown on a number line is -1/2 ≤ a ≤ 1/2.

What is magnitude and sign?

A number has both magnitude(its absolute value) and its sign(positive or negative).

Thus, for -5, the magnitude is 5, and sign is –ve.

Also, positive numbers > 0 > negative numbers.

In the number line we can clearly see that our possible values of a are in the range:

-1/2 ≤ a ≤ 1/2

And we need to find an absolute value equation such that this set is the set of possible solutions.

An example can be:

Ia - 1/2I ≤ 1/2

Notice; using the minor and equal sign, this is because the black dots means that the values a = -1/2 and a = 1/2 are included, if the dots were empty dots, it would be an open set and we should use the <  > signs.

The area of a triangle is found using the formula bh/2, where b is the base and h is the height. What is the area in square inches of a triangle with a height of 6 inches and a base of 8 inches?

Answers

Answer:

A = 24 in^2

Step-by-step explanation:

A = 1/2 bh

Let b = 8 and h = 6

A = 1/2 (8)(6)

A = 24 in^2

Given :

The area of a triangle is found using the formula bh/2, where b is the base and h is the height. What is the area in square inches of a triangle with a height of 6 inches and a base of 8 inches?

Solution :

Given Data :

Height = 6 inches

Base = 8 inches

Formula for Area of traingle is :

Answer: 1.5

Step-by-step explanation: Given:

                                       A=1/10×5 + 11²

                                        B= 5 - 11²

                              If     c = A + B

                                      c = ( 1/10×5 +11²) + ( 5 - 11² )

                                              = ( 5/10 + 121) + ( 5 - 121)

                                                = ( 121.5) + ( -120)

                                                    = 121.5 - 120

An adult ticket is twice the cost of a child's ticket. Angela paid $ 28 for two adult tickets and three children's tickets. Which of the
following equations could be used to find the price of a child's ticket?
(A) x + 2x = 28
(B) 3x + 2(2x) = 28
(C)3(2x) + 2x = 28
(D) 3x + 2x = 28

Answers

B = 3 x + 2 ( 2x ) = 28

The following equations could be used to find the price of a child's ticket,  3x + 2(2x) = 28, the correct option is B.

What is an Equation?

An equation is a mathematical statement formed when two expressions are equated using an equal sign.

The equations are useful in determination of unknown parameters.

The equations are of various types, such as Trigonometric equations, quadratic equations.

The system of equations are used to solve complex problems.

Let the cost of child ticket is $x

An adult ticket is twice the cost of a child's ticket.

Let the cost of adult ticket is $2x

The total amount Angela paid is $28 for two adult tickets and three children's tickets.

The equation that will be formed is

4x + 3x = 28

It can also be written as 3x + 2(2x) = 28.
