What theorem would you use to solve for x?

Answer: 13/21 of the American adults spend at least 6 hours on digital services.

Step-by-step explanation:

The proportion that spends between 6 hours and 9.99 hours is 1/3

The proportion that spends more than 9.99 hours is 2/7

We want to find the proportion who spends at least 6 hours.

This is easy, we just need to combine the two groups from above, and that will give use the proportion that spends 6 hours or more.

We only need to add:

1/3 + 2/7

Now, the first problem we see here is that the denominators are different, then we need to rewrite both fractions to have the same denominator.

We know that 3*7 = 21, then we can use 21 as the common denominator, by multipliying by 7/7 (this is equal to 1) the first fraction, and by 3/3 the second one:

1/3 = (1/3)*1 = (1/3)*(7/7) = 7/21

2/7 = (2/7)*1 = (2/7)*(3/3) = (3*2)/21 = 6/21

Then the previous sum becomes:

1/3 + 2/7 = 7/21 + 6/21 = 13/21

This means that 13/21 of the american adults spend at least 6 hours on digital services.

It's like a graph, you create a ratio using the x, and y or whichever numbers you're using.

Answer:

  A'(-6, 12), B'(12, -3), C'(-3, -6)

Step-by-step explanation:

When the center of dilation is not specified, it is presumed to be the origin (0, 0). When that is the case, dilation multiplies every coordinate value by the dilation factor. For example, the x-coordinate of A is -2. The dilation factor is 3, so the x-coordinate of A' is 3(-2) = -6, as shown in your figure.

The same applies to all of the coordinates. (We assume you know how to multiply by 3.)

On the graph, each point moves to 3 times the original distance from the origin, in accordance with the new coordinates. The result is shown in the attachment.

Answer:

∠A = 20°

Step-by-step explanation:

Given:

Line AB equal to line AC

So, we can say that;

∠B = ∠C

So

∠B = ∠C = 80°

Using angle sum rule

∠A + ∠B + ∠C = 180°

∠A + 80° + 80° = 180°

∠A = 20°

Answer:

y = 4

Step-by-step explanation:

In this situation, because all the angles have the same arc mark, they must have the same measure which means that the triangle is equiangular. Therefore, you can use the definition of an equilateral triangle which states that if the triangle is equiangular, it must be equilateral which means that all sides are the same. This is because x + x + x = 180 → 3x = 180 → x = 60. When you learn trigonometry, you will realize that the proportion of sides corresponds to the angles. Or you could experiment and you may realise that if the angles of the triangles are all 60° then you can only form a triangle where the sides are all equal. If all sides are the same, then 9y - 3 = 7y + 5

So if 9y - 3 = 7y + 5, then

9y - 3 = 7y + 5 →

[subtract 7y from both sides]

9y - 7y - 3 = 7y - 7y + 5 →

2y - 3 = 5 →

[add 3 to both sides]

2y - 3 + 3 → 5 + 3 → 2y = 8 →

[divide both sides by 2]

y = 4

Answer: x = 6

Step-by-step explanation:

30 + 12 = x (5 + 2)

x (5 + 2) = 30 + 12

x (7) = 42

7x = 42

Divide both sides by 7

x = 6

Answer:

30+12=x(5+2)

or,42=7x

or,x=42÷7

So,x= 6

Answer:

Slope = -4

Step-by-step explanation:

Let us solve the question

∵ The slope of the line is m = Δy/Δx

∵ Δy is the change of y ⇒ Δy = y2 - y1

∵ Δx is the change of x ⇒ Δx = x2 - x1

→ Choose from the table x1, y1 and x2, y2

∵ x1 = -3 and y1 = 12

∵ x2 = -2 and y2 = 8

→ Use them to find Δx and Δy

∵ Δx = -2 - (-3) = -2 + 3 = 1

∴ Δx = 1

∵ Δy = 8 - 12 = -4

∴ Δy = -4

→ Use them to find the slope

∵ m = Δy/Δx

∴ m = [tex]\frac{-4}{1}[/tex]

∴ m = -4

∵ m is the slope of the line

∴ The slope of the line is -4

Answer:

49

Step-by-step explanation:

∠BAD = ∠DBC       (90-∠ABD)

∠C = ∠C

ΔABC similar to ΔBDC

AC/BC = BC/AC

x/14 = 14/4

x = 14*14/4 = 49

Answer:

y = (7/9)x

Step-by-step explanation:

The equation of a straight line is given as y = mx + b, where y and x are variables, m is the rate of change = change in y / change in x, while b is the y intercept (value of y when x = 0).

When no pint is used, there is no frozen yoghurt. But from 9 pints, 7 large servings of frozen yogurt is made. Let x represent the number of pints and the y represent the number of servings.

Hence, using y = mx + b, we get b = 0, because at 0 pint there is no servings. The equation be comes y = mx

m = change in y / change in x = 7 servings / 9 pints

m = 7/9

The equation is:

y = (7/9)x

Answer:

8.75-1.5=7.25

w=7.25

Step-by-step explanation:

Answer:

w = 7.25

Step-by-step explanation:

w + 1.5 = 8.75

To find what w is, you need to isolate.  To isolate w from 1.5, you have to subtract 1.5 by 1.5.

w + 1.5-1.5 = 8.75

What you do to one side of the equal sign, you have to do to the other

w + 1.5-1.5 = 8.75 - 1.5

1.5-1.5 cancels out and 8.75 - 1.5 equals to 7.25

w = 7.25

- 7 + 10

= 3

Answer:

x = 2

Step-by-step explanation:

Parallel lines divides the transversals in proportion.

Therefore,

[tex] \frac{9}{4} = \frac{13.5}{x + 4} \\ \\ 9(x + 4) = 13.5 \times 4 \\ \\ 9(x + 4) = 54 \\ \\ x + 4 = \frac{54}{9} \\ \\ x + 4 = 6 \\ \\ x = 6 - 4 \\ \\ x = 2[/tex]

Answer:

in a triangle there is only two sides that are the same length.

Answer:

Thus the answer is A. 10 cm, 6 cm, 4 cm

Step-by-step explanation:

Triangle Inequality Theorem

Let y and z be two of the side lengths of a triangle. The length of the third side x cannot be any number. It must satisfy all the following restrictions:

x + y > z

x + z > y

y + z > x

Combining the above inequalities, and provided y>z, the third size must satisfy:

y - z < x < y + z

The first combination y=6 cm z=4 cm produces the condition:

6 - 4 < x < 10

2 < x < 10

The third side is x=10 cm and it does not satisfy the inequality.

The rest of the combinations produce true inequalities:

B. 1 < x < 15 and x=9 satisfies the conditions

C. 1 < x < 9 and x=8 satisfies the conditions

D. 6 < x < 14 and x=10 satisfies the conditions

Thus the answer is A. 10 cm, 6 cm, 4 cm

It would be 12.96

Answer:

128°

Step-by-step explanation:

In kite WXYZ, WY and XZ are longer and smaller diagonals respectively.

Longer diagonal bisects the opposite angles.

[tex] \therefore m\angle ZYW =m\angle XYW[/tex]

[tex] \because m\angle XYW = 11\degree... (given) [/tex]

[tex] \therefore m\angle ZYW =11\degree [/tex]

[tex] In\: \triangle WYZ[/tex]

[tex] m\angle ZYW + m\angle ZWY + m\angle WZY=180\degree [/tex]

[tex] 11\degree + 41\degree+ m\angle WZY=180\degree [/tex]

[tex] 52\degree+ m\angle WZY=180\degree [/tex]
