Step-by-step explanation:

To add mixed numbers, we first add the whole numbers together, and then the fractions. ...

If the denominators of the fractions are different, then first find equivalent fractions with a common denominator before adding. ...

Subtracting mixed numbers is very similar to adding them.

Step-by-step explanation:

x ≤ 3 or x ≥ -1 represent the given graph.

Option (4) is correct.

Inequalities are mathematical formulas in which neither side is equal. Unlike equations, we compare two values in inequality.

As per the given diagram:

A line is drawn and a certain range of values are marked on the line,

To find the compound inequality that could be represented by the graph.

Because a number line with only real numbers is displayed in the provided graph.

We identify the solution set for each option by considering it separately.

1) -4 ≤ x ≤ 4

Since, the solution set contain only numbers between -4 and 4.

So it is false.

2) -2 ≤ x ≤ -1

This is a wrong representation.

3) x ≤ -1 or x ≥ 0

This represents all real numbers, excluding numbers between -1 and 0

So it is false.

4) x ≤ 3 or x ≥ -1

So it represents all the real numbers on number lines as shown in the graph below.

So, it is true.

x ≤ 3 or x ≥ -1 represent the given graph.

Answer:

Step-by-step explanation:

delta math

The length of t is approximately 43.60 cm, to the nearest centimeter.

The properties of the triangle are:

1. The sum of all the angles of a triangle (of all types) is equal to 180°.

2. The sum of the length of the two sides of a triangle is greater than the length of the third side.

3. In the same way, the difference between the two sides of a triangle is less than the length of the third side.

To find the length of side t in triangle RST, we can use the law of cosines, which relates the lengths of the sides and the cosine of one of the angles in a triangle:

[tex]c^2 = a^2 + b^2 - 2ab cos(C)[/tex]

where c is the length of the side opposite the angle C, and a and b are the lengths of the other two sides.

In this case, we know that:

r = RS = 52 cm

s = ST = 55 cm

∠T = 48°

So, we want to find the length of t, which is the side opposite the angle T.

Let's call the length of t "c". Then, applying the law of cosines, we have:

[tex]c^2 = r^2 + s^2 - 2rs cos(T)\\\\c^2 = (52 cm)^2 + (55 cm)^2 - 2(52 cm)(55 cm) cos(48^0)\\\\c^2 = 1901.57[/tex]

Taking the square root of both sides, we get:

c= 43.60 cm

Therefore, the length of t is approximately 43.60 cm, to the nearest centimeter.

Answer:

  -12, -21

Step-by-step explanation:

Let x represent the first number. Then the second is x-9. The other relation is ...

  4x = 2(x-9) -6

  2x = -24 . . . . . subtract 2x, simplify

  x = -12

  x-9 = -21

The first number is -12; the second number is -21.

Step-by-step explanation:

=> 5y-8=3y+1

=> 5y-3y=1+8

=> 2y=9

=> y=4.5

=> x+6=4x

=> 6=4x-x

=> 6=3x

=> x=(6/3)

=> x=2

Thus, x=2 and y=4.5 [Option C]

Hope this helps you.

Answer:

x = 40

y = 15

Step-by-step explanation:

Given is an equilateral triangle.

Measure of each angle of an equilateral triangle is 60°.

Therefore,

(x + 20)° = 60°

x + 20 = 60

x = 60 - 20

x = 40

4y = 60

y = 60/4

y = 15

Answer:

1.3 & 1/3

Step-by-step explanation:

Answer/Step-by-step explanation:

A1. Reference angle = 41°

Hypotenuse = x

Adjacent = 7

Thus, applying trigonometric ratio, we would have:

Cos 41 = 7/x

Multiply both sides by x

x × cos 41 = 7

Divide both sides by cos 41

x = 7/cos 41

x = 9.3 (nearest tenth)

A2. Reference angle = 65°

Hypotenuse = 6

Opposite = y

Thus, applying trigonometric ratio, we would have:

Sin 65 = y/6

Multiply both sides by 6

6 × sin 65 = y

5.4 = y (nearest tenth)

y = 5.4

A3. Reference angle = 50°

Hypotenuse = z

Opposite = 8

Thus, applying trigonometric ratio, we would have:

Sin 50 = 8/z

Multiply both sides by z

z × sin 50 = 8

Divide both sides by sin 50

z = 8/sin 50

z = 10.4 (nearest tenth)

B1. Reference angle = 49°

Hypotenuse = x

Opposite = 7

Thus, applying trigonometric ratio, we would have:

Sin 49 = 7/x

Multiply both sides by x

x × sin 49 = 7

Divide both sides by sin 49

x = 7/sin 49

x = 9.3 (nearest tenth)

B2. Reference angle = 25°

Hypotenuse = 6

Adjacent = y

Thus, applying trigonometric ratio, we would have:

Cos 25 = y/6

Multiply both sides by 6

6 × cos 25 = y

y = 5.4 (nearest tenth)

B3. Reference angle = 40°

Hypotenuse = z

Adjacent = 8

Thus, applying trigonometric ratio, we would have:

Cos 40 = 8/z

Multiply both sides by z

z × cos 40 = 8

Divide both sides by cos 40

z = 8/cos 40

z = 10.4 (nearest tenth)

Answer:

x=9

Step-by-step explanation:

Original equation: 16x-8-14x=10

Combine like terms: 2x-8=10

Add 8 to both sides: 2x=18

Divide by 2 on both sides: x=9

Let me know if this helps!

Answer:

x=9

Step-by-step explanation:

16x-8-14x=10

16x+-8+-14x=10

(16x+-14x)+(-8)=10 ( Combine like terms)

2x-8=10

Add 8 to both sides

2x-8=10

+8 +8

2x=18

Divide both sides by 2

2x=18/2

x=9
