Answer:

percentage of increase = 49%

Step-by-step explanation:

Percentage change for any value is given by

percentage change = (new value - old value)/old value * 100 %

If there is increase in new value, percentage change can be called as percentage increase.

If there is decrease in new value, percentage change can be called as decrease increase.

Distance covered in first half of game = 50.5 yards

Distance covered in first full game = 75 yards

percentage of increase = (Distance covered in first full game - Distance covered in first half of game)/Distance covered in first half of game * 100 %

percentage of increase = (75 - 50.5)/50.5 * 100% = 24.5/50 * 100%

percentage of increase = 49%  answer

Step-by-step explanation:

First, multiply

2x - 8 + x = 3x - 24 + 16

Combine like terms

6x -8 = -8

Add 8

6x = 0

so the answer should be 0

Answer:

Add 8 to both sides

Subtract 6x from both sides.

To solve the given linear equation , next steps to be followed

1. Subtract 6x from both sides.

2. Add 8 to both sides.

A linear equation is an equation in which the highest power of the variable is always 1. It is also known as a one-degree equation. The standard form of a linear equation in one variable is of the form Ax + B = 0. Here, x is a variable, A is a coefficient and B is constant.

Given linear equation

4(x – 5) + 2x = 9x – 2(4 + 2x)

Step 1: 4x - 20 + 2x = 9x - 8 - 4x

Step 2: 6x - 20 = 5x - 8

Next step is Subtract 6x from both sides.

Step 3: 6x - 20 - 6x = 5x - 8 - 6x

⇒ -20 = -x - 8

Next step is Add 8 to both sides.

Step 4: -20 + 8 = -x - 8 + 8

⇒ -12 = -x

⇒ x = 12

Hence,

To solve the given linear equation , next steps to be followed

1. Subtract 6x from both sides.

2. Add 8 to both sides.

Step-by-step explanation: I would advise writing out the equation

by simply reading the problem from left to right and solving it from there.

So for this problem we have "what percent."

Since "percent" means over 100 and "what"

means x, "what percent" would be x/100.

The word "of" means times, 300 is 300, "is" means equals, and 26 is 26.

So we have x/100 · 300 = 26.

We can rewrite this problem as 300x/100 = 26.

To get rid of the fraction, we multiply both sides

by 100 and we have 300x = 2600.

Dividing both sides by 300, you can use a calculator to

find that x = 8.66666 which rounded to 8.67.

So 8.67% of of 300 is 26.

Answer:

angles   100.6 and 79.4   = 180 degrees

Step-by-step explanation:

supplementary angles add to 180

angles   100.6 and 79.4   = 180 degrees

100.6 -21.20= 79.4

x+ x-21.2 = 180

2x = 158.8

x= 79.4

  79.4 + 21.2= 100.6

Answer:

Step-by-step explanation:

The total amount of money earned by Kerri is $135.

Given that, Kerri earns $15 an hour tutoring.

In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.

Let the total amount of money earned by Kerri be x.

Now, total number of hours = 2+3+4=9 hours

Total money = Number of hours worked × Amount earned in an hour

x=9 × 15

⇒ x = 135

Therefore, the total amount of money earned by Kerri is $135.

Answer:x=2

Step-by-step explanation:

The value of x in the equation 2.5(6x - 4) = 10 + 4(1.5 +0.5x) is 2.

The correct option is C.

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

We have,

2.5(6x - 4) = 10 + 4(1.5 +0.5x)

Solving the equation for x we get

15x - 10 = 10 + 6 + 2x

15x - 2x = 16 + 10

13x = 26

Divide both side by 13 we get

13x/ 13 = 26 /13

x= 2

Thus, the value of x is 2.

Answer: Largest = 404999

Smallest = 395,000.

Step-by-step explanation:

Given data:

Number of people in attendance = 400,000

Solution:

If we were to round off to the nearest ten thousand the greatest number we can get would be = 404999.

And following the same principle the smallest number we would be able to get would be = 395000

Therefore, the largest number of people who could have attended the inauguration would be 404999.

And the smallest number of people who could have attended would be 395000.

Answer:

x = 1.639 in

Step-by-step explanation:

With these instructions, the length of the box would be (14-2x), the width would be (8-2x), and the height would be x, so the equation for volume would be width*length*height, or

[tex]V=(14-2x)(8-2x)(x)[/tex]

[tex]V=4x^3-44x^2+112[/tex]

Now we solve for dV/dx because we want to find maximum volume

[tex]\frac{dV}{dx} =12x^2-88x+112[/tex]

[tex]\frac{dV}{dx} =4(3x^2-22x+28)[/tex]

Now we let dV/dx equal zero to find critical values

[tex]0=4(3x^2-22x+28)[/tex]

[tex]0=3x^2-22x+28[/tex]

[tex]x=\frac{11+\sqrt{37} }{3}[/tex], [tex]x=\frac{11-\sqrt{37} }{3}[/tex]

Now we see where dV/dx changes signs:

dV/dx changes from positive to negative at [tex]\frac{11-\sqrt{37} }{3}[/tex]

and from negative to positive at [tex]\frac{11+\sqrt{37} }{3}[/tex]

so V(x) has a local maximum when x = [tex]\frac{11-\sqrt{37} }{3} = 1.639[/tex] in
