Answer:

There are two orders in which we can do the steps:

1. GAFDC

2. GABEC

Step-by-step explanation:

$4x-8=5x-2(x+2)$

Step 1 :G Using distributive property to remove parenthesis:

$4x-8=5x+(-2\times x-2\times2)$

$4x-8=5x-2x-4$

Step 2:A Collect like terms:

$4x-8=3x-4$

Step 3: F Add 8 to both sides:

$4x-8+8=3x-4+8$

$4x=3x+4$

Step 4: D Subtract $3x$ from both sides:

$4x-3x=3x+4-3x$

$x=4$

Solution:C

$x=4$

$4x-8=5x-2(x+2)$

Step 1 :G Using distributive property to remove parenthesis:

$4x-8=5x+(-2\times x-2\times2)$

$4x-8=5x-2x-4$

Step 2:A Collect like terms:

$4x-8=3x-4$

Step 4: B Subtract $3x$ from both sides:

$4x-8-3x=3x-4-3x$

$x-8=-4$

Step 3: E Add 8 to both sides:

$x-8+8=-4+8$

$x=4$

Solution:C

$x=4$

There are two orders in which we can do the steps:

Find the missing side length in the image below

Travka [436]

Let missing side be x

Using basic proportionality theorem

$\\ \sf\longmapsto \dfrac{45}{35}=\dfrac{x}{56}$

$\\ \sf\longmapsto \dfrac{9}{7}=\dfrac{x}{56}$

$\\ \sf\longmapsto 7x=9(56)$

$\\ \sf\longmapsto x=\dfrac{9(56)}{7}$

$\\ \sf\longmapsto x=72$

Instruction: use the ratio of a 30-60-90 triangle to solve for the variables. Leave your answers as radicals in simplest form.u=

almond37 [142]

Let's start by identify a 30-60-90 triangle

If we compare those two traingles we can stablish the following relation:

$\begin{gathered} a\sqrt[]{3}=6\sqrt[]{3} \\ \end{gathered}$

Therefore, a=6

u is the opposite side to the 90° angle, therefore

$\begin{gathered} u=2a \\ u=2\cdot6 \\ u=12 \end{gathered}$

on the other hand, v is the opposite side to the 30° angles, so

$\begin{gathered} v=a \\ v=6 \end{gathered}$

What is the approximate distance from the origin to the point (3, −4, 5)? Round to the nearest unit. 4 units 7 units 8 units 9 u

Dafna11 [192]

Answer:

Option B is correct.

Step-by-step explanation:

The distance formula used is:

$d=\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2+(z_{2}-z_{1})^2}$

We need to find distance between origin and other point (3,-4,5)

Origin is: (0,0,0)

x₁ = 0, y₁ = 0, z₁ =0 and x₂= 3, y₂= -4 and z₂ = 5

Putting values in the distance formula we get:

$d=\sqrt{(3-0)^2+(-4+0)^2+(5-0)^2}\\d=\sqrt{(3)^2+(-4)^2+(5)^2}\\d=\sqrt{9+16+25}\\d=\sqrt{50}\\d=7$

The Distance from the origin to the point (3, −4, 5) is 7 units.

Option B is correct.

Stacy uses a spinner with six equal sections numbered 2, 2, 3, 4, 5, and 6 to play a game. Stacy spins the pointer 120 times and

Alex17521 [72]

Answer:

The solution is given below;

Step-by-step explanation:

The computation is shown below:

There is six equal sections are numbered i.e. 2, 2, 3, 4, 5, and 6.

And, Number of Outcome of 2 on the Spinner is 2

Also, total Number of Sections is 6

As the winning spin is a 2

So, The theoretical probability of winning

= 2 ÷6 × 100

= 33.33%

Now

There is a total no of trials be 120

And, the number of outcome of 2 be 30

So, the experimental probability is 30 ÷ 120 = 1 ÷ 4 × 100 = 25%

As 33.3%>25%, this represent that the theoretical probability of winning would be greater.
