Answer:

x=10

Step-by-step explanation:

I'm assuming you needed to solve for x. Here is how you do it:

first, divide both sides by 4/5 to get x by itself.

this will give you x=8 divided by 4/5.

To solve 8 divided by 4/5 you do keep switch flip.

keep the first number (8), switch the sign (division to multiplication), and flip the other fraction (4/5 to 5/4) then you can just multiply across the top (8/1 *5/4) which equals 40/4. This simplified is 10

Answer:

- 3

Step-by-step explanation:

3 times the sum of 5 and 4 is subtracted from 30

i.e.,

3 × (5 + 4) - 30

3 × 9 - 30

27 - 30 = - 3

Thus, 3 times the sum of 5 and 4 is subtracted from 30 is equal to -3

Answer:

12

Step-by-step explanation:

 This is a joint variation problem:

              z varies directly as x and y

Interpreting this;

                z ∝ xy

 Therefore;

               z  = kxy

 z = 6, x = 2, y  = 6

   Now find k,

             6  = 2 x 6 x k

              6  = 12k

               k  = [tex]\frac{1}{2}[/tex]

To find the value of z;

   x  = 3, y  = 8

              z  =  [tex]\frac{1}{2}[/tex]  x 3 x 8  = 12

Required slope intercept form is [tex]y = - \frac{3}{5} x + 3[/tex]

What is slope ?

The slope of a line is a measure of the steepness and direction of the line. Finding the slope of lines in a coordinate plane can help predict whether the lines are parallel, perpendicular, or missing without using a compass.

The slope of any straight line can be calculated using two points on the line. The slope of the line formula calculates the ratio of "vertical change" to "horizontal change" between two different points on the line. In this article we will understand the slope finding method and its applications.

The slope of a line is defined as the change in the y-coordinate relative to the change in the x-coordinate of that line. The net change in the y-coordinate is Δy, while the net change in the x-coordinate is Δx. Thus, the change in the y-coordinate with respect to the change in the x-coordinate can be written as: m = Δy/Δx

Here given,Equation of line [tex] \frac{5}{3}y = - (x - 5)[/tex]

We want to find what is 5/3y=-(x-5) in slope intercept form ?

We want to simplify the equation.

[tex]5y = - 3(x - 5) \\ 5y = - 3x + 15 \\ y = \frac{ - 3x + 15}{5} \\ y = - \frac{3}{5} x + \frac{15}{5} \\ y = - \frac{3}{5} x + 3....(1)[/tex]

We know slope in line y = mx+c is m.

We are comparing equation (1) with y = mx + c and get [tex]m = - \frac{3}{5} [/tex]

Equation (1) is slope intercept form of 5/3y=-(x-5).

Therefore,required slope intercept form is [tex]y = - \frac{3}{5} x + 3[/tex]

Explanation:

Sort the values from smallest to largest: {2, 5, 6, 10, 10}

Now cross off the first and last values to get this smaller set: {5, 6, 10}

Repeat the process one more time and we get this: {6}

This shows 6 is the middle most item of the original sorted set above. Therefore, 6 is the median.

Answer:

the first equation, y = 9/4 x

Step-by-step explanation:

according to the equation for slope-intercept form y=mx+b, the m represents the slope indicating that the 9/4 would be placed there with the exponent of x attached to it. And the y-intercept is represented by the b in the equation, and since it is 0 in this case you will not need to add it in the equation. so your final answer would be y=9/4x

Answer:

17.0 ft

Step-by-step explanation:

Let h be the height of the base of the window from the ground, L be the length of the ladder = 18 ft and d be the distance of the ladder from the wall = 6 ft. Now, these three lengths form a right-angled triangle with the length of the ladder, L as the hypotenuse side.

So, using Pythagoras' theorem,

L² = h² + d²

So, h = √(L² - d²)

Substituting the values of L = 18 ft and d = 6 ft, we have

h = √((18 ft)² - (6 ft)²)

= √(324 ft² - 36 ft²)

= √288 ft²

= 16.97 ft

≅ 17.0 ft

165x12=1980

1980-1560=420

Answer:

$420

Step-by-step explanation:

The last rate was $165, and the new one is $130. To find the difference, do this equation, 165-130=?. From that equation, you get $35. As you know, there are 12 months in a year, so you multiply $35 by 12 to get $420. There is your answer.

Answer:

C.-9, -1, -3,5

Step-by-step explanation:

Given

y = 2x - 3 ---- [missing equation]

Required

Complete the table

To do this, we simply substitute the values of x in the given equation.

When x = -3

y = 2 * -3 - 3

y = -6 - 3

y = -9

When x = 1

y = 2 * 1 - 3

y = 2 - 3

y = -1

When x = 0

y = 2 * 0 - 3

y = 0 - 3

y = -3

When x = 4

x = 2 * 4 - 3

y = 8 - 3

y = 5

Hence, the missing gap can be filled with: C.-9, -1, -3,5
