Prove that x = 50 in the following equation: 1/5x – 5 = 5

Write the equation:

1/5x – 5 = 5

Add 5 to both sides:

1/5x – 5 + 5 = 5 + 5

1/5x = 10

Multiply each side by 5:

5 × 1/5x = 10 × 5

–5 + 5 cancels out, leaving you with:

1x = 10 × 5

1x = 50

Divide both sides by 1 to get x:

1x/1 = 50/1

The 1 cancels out:

x = 50/1

Answer:

x = 50 ✔

Check your work by plugging in 50 as x:

1/5x – 5 = 5

1/5 × 50 – 5 = 5

Multiply:

1/5 × 50/1 – 5 = 5

50/5 – 5 = 5

Get rid of the fraction by dividing:

50 ÷ 5 = 10

10 – 5 = 5

Subtract:

10 – 5 = 5

5 = 5 ✔

I have just proven that x = 50 because the answer I got when I checked my work was balanced. Hope that helps! Have an amazing rest of your day! :)

The value of the first number is 9 , and

the value of the second number is 8 .

In the question ,

statements about two numbers is given ,

let the first number be x ,

let the second number be y .

According to the first statement " One number is one more than a second number "

translating it into the equation form , we get

x=y+1      ...(i)

According to the second statement which states " Five times the first is 3 less than 6 times the second "

translating it into the equation form , we get

5*x = 6*y - 3

5x = 6y - 3

Substituting the value of x from equation (i) , we get

5(y+1) = 6y - 3

5y + 5 = 6y - 3

6y-5y = 5+3

y = 8 ,

substituting  y=8 in the the equation (i) ,

x = 8 + 1

x = 9

hence the first number = 9  and the second number = 8 .

Therefore , the value of the first number is  9, and

the value of the second number is 8 .

The equation of the linear function represented by the given table in slope intercept form is y = 2x - 2.

The equation of line can be determine using the slope-intercept formula;

y = mx + b

Where m is slope and b is the y-intercept.

From the given table, we use to points;

Point 1( -1, -4 )

Point 2( 1, 0 )

First, we find the slope of the line.

Slope m = (y₂ - y₁) / (x₂ - x₁ )

Slope m = ( 0 - (-4) ) / (1 - (-1) )

Slope m = ( 0 + 4) ) / (1 + 1) )

Slope m = 4 / 2

Slope m = 2

Next, we find the y-intercept b, using a slope m = 2 and a point ( -1, -4 ).

y = mx + b

-4 = 2(-1) + b

-4 = -2 + b

b = -4 + 2

y-intercept b = -2

Now that we have the slope m and y-intercept b, plug the values into to y = mx + b to determine the equation of line.

y = mx + b

y = 2x + (-2)

y = 2x - 2

Therefore, the equation of the linear function is y = 2x - 2.

Step-by-step explanation:

The approximate number of grains of salt it would take to reach the height of Mt. Everest is; 0.2963 * 10⁸

We are given;

Approximate length of a grain of salt = 9.8 * 10⁻⁴ ft

Approximate height of Mt. Everest = 2.9035 * 10⁴ ft

Now, we want to know the approximate number of grains of salt it would take to reach the height of Mt. Everest. To get this it means we have to divide the Approximate height of Mt. Everest by the Approximate length of a grain of salt.

According to Laws of exponents, we know that;

x³/x² = x^(3 - 2) = x¹

Thus;

Approximate number of grains of salt it would take to reach the height of Mt. Everest = (2.9035 * 10⁴)/(9.8 * 10⁻⁴) = (2.9035/9.8) * (10⁴⁻⁽⁻⁴⁾) = 0.2963 * 10⁸

The number obtained by multiplying 5 and square root 164 is 64.

The square root operator in mathematics can be defined as a factor of a number that, when multiplied by itself, gives the original number.

The square root operator in mathematics is denoted by the symbol "√".

The problem 5 (square root of 164) is calculated as follows;

5 ( square root of 164) = 5√164

5√164 = 5(12.8) = 5 x 12.8 = 64

Thus, we can conclude that using the mathematics operator  "√", the number obtained from 5 (square root of 164)  will be greater than 5 but less than 164.

The distance between the starting point and the second obstacle is 13 meters.

And the total length of one lap is equal to the perimeter of the triangle, which measures 30 meters.

We can see that this distance is equal to the hypotenuse of the triangle on the image.

The two legs measure:

5 meters and 12 meters.

Then using the Pythagorean theorem we can write:

d^2 = 5^2 + 12^2

d = √(5^2 + 12^2) = 13

So the distance between the starting point and obstacle 2 is 13 meters.

Answer:

Step-by-step explanation:

since QR ≅ RS , the triangle is isosceles with base angles congruent, so

∠ Q = ∠ S , that is

8x - 17 = 5x + 1 ( subtract 5x from both sides )

3x - 17 = 1 ( add 17 to both sides )

3x = 18 ( divide both sides by 3 )

x = 6

Then

∠ Q = 8x - 17 = 8(6) - 17 = 48 - 17 = 31°

∠ R = 19x + 4 = 19(6) + 4 = 114 + 4 = 118°

∠ S = 5x + 1 = 5(6) + 1 = 30 + 1 = 31°

Answer:

The area of Ava's closet is 2 square feet.

Step-by-step explanation:

The area of the bedroom is 36 and it is 6 times as many square feet as her closet. They are basically saying that the closet has 1/6th the area of the bedroom.

Now we can form an equation to find the area of her closet.

36 ÷ 6 = 6

So, therefore, the area of the closet is 6 square feet.

We know the width of the closet, which is 3 feet. Since the formula of area for her closet is Length × Width, we can form an equation for this.

X in this equation is what we are trying to solve for, which is the length of the closet.

X = 6 ÷ 3

X = 2

So, therefore, the area of Ava's closet would in the end be 2 square feet.
