\huge\textsf{Hey there!}

\mathsf{\dfrac{x}{3}-2=6}

\mathsf{= \dfrac{1}{3}x - 2 = 6}

\textsf{ADD 2 BOTH SIDES}

\mathsf{\dfrac{1}{3}x - 2 + 2 = 6 + 2}

\textsf{CANCEL out: -2 + 2 because that gives you 1}

\textsf{KEEP: 6 + 2 because that helps solve for x}

\mathsf{6 + 2 = \boxed{\bf 8}}

\mathsf{NEW \ EQUATION: \dfrac{1}{3}x = 8}

\textsf{MULTIPLY 8 to BOTH SIDES}

\mathsf{3\times\dfrac{1}{3}x=3\times8}

\mathsf{CANCEL\  out: \ 3 \times  \dfrac{1}{3} \  because \ that \ gives \ you \  1}

\mathsf{KEEP: \  3 \times 8 \ because \ that\  gives \ you \ the \ value \ of \ x}

\mathsf{\boxed{\bf x}= 3\times8}

\mathsf{3\times8 = \boxed{\bf x}}

\boxed{\boxed{\large\textsf{Answer: \huge \bf x = 24}}}\huge\checkmark

Sergeu [11.5K]
Hi,

To find the middle. You need to sum both numbers and divide them with 2.

\frac{2.2 + 8.5}{2} = \frac{10.7}{2} = 10.7 \div 2 = 5.35

Answer: A (5.35)

Hope this helps.
If you have any questions about the answer, leave a comment and I will reply.

1. ADEA has vertices D(8,4), E(2, 6), and F(3, 1). What are the vertices of the image after a dilation with a scale factor of 5
lubasha [3.4K]

Answer:

The vertices of the image are D' (40, 20), E' (10, 30), F' (15, 5)

Step-by-step explanation:

If the point (x, y) dilated by a scale factor k using the origin as a center of dilation, then its image is (kx, ky)

Let us use this rule to solve our question

∵ The vertices of ΔDEF are D (8, 4), E (2, 6), and F (3, 1)

∵ ΔDEF dilated by a scale factor 5

∴ k = 5

∵ The origin as the center of dilation

→ That means, multiply the coordinates of every point by 5

∴ D' = (8 × 5, 4 × 5)

∴ D' = (40, 20)

∴ E' = (2 × 5, 6 × 5)

∴ E' = (10, 30)

∴ F' = (3 × 5, 1 × 5)

∴ D' = (15, 5)

∴ The vertices of the image are D' (40, 20), E' (10, 30), F' (15, 5)

12 m 20 m 16 m 6m 10m x find the length represented by x for each pair of similar triangles
defon

Answer:

<h2>x = 8m</h2>

Step-by-step explanation:

Let the two triangles be represented as A and B.

Given two triangles with sides 12m 20m 16m and 6m 10m x.

Lengths of sides of triangle A = 12m, 20m, 16m

Lengths of sides of triangle B = 6m, 10m, x

It can be seen that each length of triangle A are twice that of B i.e triangle B dilated by a factor of 1/2.

A = 2B

<u>Considering the 16m length in triangle A  and comparing it with the 'x'm length in triangle B, we can get the unknown length x as shown;</u>

16 = 2x

x = 16/2

x = 8m
