What fractions are equal to 9 /12

Answer:

That is written in standard form. Hope this helps.

Answer:

In order for the average to equal 3,000 then the total attendance must equal 9,000.

Show 1 = 2,580

Show 2 = 2,920

2 show total = 5,500

Therefore, third show total must equal 9,000 minus 5,500 =

3,500

Double-Check

2,580 + 2,920 + 3,500 = 9,000

Step-by-step explanation:

x = -6 is the solution to the equation 6x + 7 = 13 + 7x

To solve the equation 6x + 7 = 13 + 7x, you can follow these steps:

Group the x terms on one side and the constant terms on the other side:

6x - 7x = 13 - 7

Combine like terms:

-x = 6

Multiply both sides of the equation by -1 to isolate x:

-1*(-x) = -1*6

This simplifies to:

x = -6

Therefore, the solution to the equation 6x + 7 = 13 + 7x is x = -6.

[tex]x = 19[/tex]

Step-by-step explanation:

If two lines are perpendicular, they create 4 90° angles. Meaning, in this case, that m<DBC = 90 and m<DBA = 90.

We're given that m<DBE = 2x - 1 and that m<CBE = 5x - 42.

The sum of angles DBE and CBE = m<DBC = 90°

We can add the two angles and set it equal to 90 to find x

Answer:

5,500,000 = (5 x 100000000) + (0 x 10000000) + (5 x 1000000) + (0 x 100000) + (0 x 10000) + (0 x 1000) + (0 x 100) + (0 x 10) + (0 x 1)

Step-by-step explanation:

The expanded form of 5,500,000 is  (5 x 1000000) + (5 x 100000) + (0 x 10000) + (0 x 1000) + (0 x 100) + (0 x 10) + (0 x 1).

The expanded form of the number is the splitting of numbers based on the place value, such as ones, tens, hundreds, thousands, ten thousands,and so on. The number that is represented by the sum of each digit multiplied by its place value is called the expanded form of the number.

Now the given number is,

5,500,000

Now each digit place value is given as,

5 =  (5 x 1000000)  

5 =  (5 x 100000)

0 =  (0 x 10000)

0 =  (0 x 1000)  

0 =  (0 x 100)

0 =  (0 x 10)

0 =  (0 x 1)

Adding this together, we get

5,500,000 = (5 x 1000000) + (5 x 100000) + (0 x 10000) + (0 x 1000) + (0 x 100) + (0 x 10) + (0 x 1).

By setting up the question as an algebraic equation, 1/2 * x = 21, and solving for x, it's determined that half of 42 is equal to 21.

The question we're looking to solve is: "1/2 of what number is 7 times 3?" First, let's understand that 7 times 3 equals 21. The question asks which number, when halved, gives us 21. This can easily be set up as an algebraic equation: 1/2 * x = 21, where x represents the number we're trying to find.

To solve for x, we first multiply both sides of the equation by 2 to get rid of the fraction (1/2). This leaves us with: x = 21 * 2. Therefore, x = 42. The number, when cut in half, that results in 21, is 42.

The original price was 142 dollar.

Suppose the value of which a thing is expressed in percentage is "a' the percent that considered thing is of "a" is b%. Then since percent shows per 100 (since cent means 100), thus we will first divide the whole part in 100 parts.

To find the original price of the item that was reduced by 20% to $126.40, divide the sale price by 0.80, which yields an original price of $158.00.

To determine the original price of an item that has been marked 20% off, we need to work backward from the sale price. The sale price represents 80% of the original price because 100% - 20% = 80%.

The question is provided with the reduced price which is $126.40. To find the original price, we divide the reduced price by 0.80.

Therefore, the original price of the item was $158.00.

Answer:

Rose wins the game, with 6 points over Lilly's 1 point.

Step-by-step explanation:

Let's find Lilly's score. In this example we will add together the gains first, so we wouldn't have to deal with negative numbers, and after, we subtract the losses of each person.

Lilly's points:

[tex]0 + 5 + 5 + 3 - 12 = 1[/tex]

Rose's points:

[tex]0 + 6 + 7 - 3 - 3 - 1 = 6[/tex]

Rose wins the game with a 5 point lead.

Lilly's score is 1 and Rose's score is 6. Therefore, Rose wins the game because 6 is greater than 1.

To find Lilly and Rose's score, we will create and solve an expression that reflects each player's game moves.

Lilly gains 5 points two times, loses 12 points, and then gains 3 points. We can express this as (5*2) - 12 + 3. First, we multiply 5 by 2, which equals 10. Then, we subtract 12 from 10, which gives -2. Finally, we add 3 to -2, resulting in a final score of 1 for Lilly.

Rose loses 3 points two times, loses 1 point, gains 6 points, and gains 7 points. We can write this as (-3*2) - 1 + 6 + 7. First, we multiply -3 by 2, which equals -6. Then, we subtract 1 from -6 yielding -7. After that, we add 6 to -7, getting -1. Lastly, we add 7 to -1, resulting in a final score of 6 for Rose.

Rose won the game because her final score of 6 is higher than Lilly's final score of 1.

Step-by-step explanation:

The absolute value always returns a positive value, however the expression inside can be positive or negative, that is

Given

| z - 7 | - 2 = 2 ( add 2 to both sides )

| z - 7 | = 4, then

z - 7 = 4 OR - (z - 7) = 4

z = 4 + 7 = 11 OR

- z + 7 = 4

- z = 4 - 7 = - 3 ( multiply both sides by - 1 )

z = 3

As a check

z = 11

| 11 - 7 | - 2 = | 4 | - 2 = 4 - 2 = 2 ←  True

z = 3

| 3 - 7 | - 2 = | - 4 | - 2 = 4 - 2 = 2 ← True

Hence z = 11 or z = 3 are the solutions

Answer:

r = -29/20 or r = -1.45

Step-by-step explanation:

I believe you are saying that the equation is -2 1/4 = r - 4/5. If so, then I would solve it in this way:

-2 1/4 = r - 4/5

-9/4 = r - 4/5

-9/4 (20) = r (20) - 4/5 (20)

-45 = 20r - 16

20r = -29

r = -29/20

r = -1.45

Check:

-2 1/4 = r - 4/5

-9/4 = r - 4/5

-2.25 = r - 0.8

-2.25 = -1.45 - 0.8

-2.25 = -2.25

-9/4 = -9/4

The calculated value of variable r is r = -1.45.

An equation is a mathematical statement that shows the equality between two expressions. It typically consists of variables, constants, and mathematical operations (e.g., addition, subtraction, multiplication, division) with an equal sign (=) in between.

To solve for r in the equation -21/4 = r - 4/5

Step 1: Add 4/5 to both sides of the equation to isolate r:

r = -2.25 + 4/5

Convert -2.25 to a fraction with a common denominator of 5:

r = (-11.25/5) + (4/5)

Add the fractions:

r = (-11.25 + 4)/5

Simplify:

r = -7.25/5

r = -1.45

So, r = -1.45.

Answer:

Additional amount of clearance between the truck and overpass is 16.8 inches.

Step-by-step explanation:

A law states that a a freight truck must have the clearance of at least 3 feet to travel under the a overpass.

Sign on an overpass states that the overpass is 18 feet above the road's surface.

Height of the truck is 13.6 feet.

As per rule height of overpass from the road must be height of the truck + clearance.

Additional amount of clearance between the truck and the overpass

= Distance between the road and the overpass - (height of the truck + clearance)

= 18 - (13.6 + 3)

= 18 - 16.6

= 1.4 feet

Since 1.4 feet = 12 inches

1.4 feet = 12×1.4 = 16.8 inches

Therefore, additional amount of clearance between the truck and overpass is 16.8 inches.

Answer:

Option C.

Step-by-step explanation:

Let x be the distance from holes center in feet and y be the depth from level ground in feet.

The given table represents a quadratic functions.

x :    -2             0           2

y :    -6            -8          -6

The depth from level ground in feet is same at x=-2 and x=2 it means the hole is symmetric about the line x=0.

The value of a quadratic function is on its extreme at line of symmetry.

In the given function the line of symmetry is x=0. So, the depth of the hole is defined on x=0.

From the table it is clear that at x=0 the depth from level ground is 8 feet.

Therefore, the correct option is C.
