15-(4m - 5) = 32 please help me

**Answer:**

m = -3

**Step-by-step explanation:**

15 - (4m - 5) = 32 (Given)

15 - 4m + 5 = 32 (Distributed)

20 - 4m = 32 (Added like terms)

20 - 4m - 20 = 32 - 20 (Subtract 20 on both sides)

-4m = 12 (Simplify)

Solve using substitution.

6x + y = 7

8x + 9y = 17

(_,_)

Please help me I really need it

You take the first equation and make a value for y. So 6x + y =7 change it to :

y = -6x + 7

Now in the second equation replace the “y” with -6x +7 this is what it means to use substitution method . Your combined equation will now be :

8x + 9(-6x + 7) =17

Now do distributive property and you get :

8x + -54x +63 =17

Now combine like terms ;

-46x +63 =17

-46x =-46

x = 1

Now replace 1 for X value and we can get the value of Y .

Y=1

X=1

y = -6x + 7

Now in the second equation replace the “y” with -6x +7 this is what it means to use substitution method . Your combined equation will now be :

8x + 9(-6x + 7) =17

Now do distributive property and you get :

8x + -54x +63 =17

Now combine like terms ;

-46x +63 =17

-46x =-46

x = 1

Now replace 1 for X value and we can get the value of Y .

Y=1

THANK YOU

Theresa and her nine classmates took a standardized test. Their scores were: 88, 49, 92, 47, 61, 94, 94, 76, 79, and 92. Theresa received an 88 on the test. Which percentile is she in

Answer: 60th

Step-by-step explanation:

First order the values from least to greatest:

47, 49, 61, 76, 79, 88, 92, 92, 94, 94.

We can note that the 88 is the 6th of 10 values, so 6/10 = 0.60 or the 60th percentile.

Theresa is in 60 **percentile**.

A test that is **administered **and scored in a consistent, or "**standard**," manner is known as a **standardized **test. The questions and interpretations on **standardized **tests are designed to be consistent and are administered and scored in a predetermined, **standard **manner.

A **standardized **test is one in which the same test is given to all test takers in the same way and **graded **in the same way for everyone.

Given scores

88, 49, 92, 47, 61, 94, 94, 76, 79, and 92.

arrange in **increasing **order,

47, 49, 61, 76, 79, 88, 92, 92, 94, 94

Theresa got 88, which is **sixth **term

percent = term x 10

**percent **= 6 x 10 = 60%

Hence, **she **is in 60%.

Step-by-step explanation:

A cube has a volume of 125 cubic inches. What is the length of each edge?

Enter your answer in the box.

(Needs to be in inches)

The formula for the volume of a cube is V = a^3.

We know the volume is 125 cubic inches.

125 = a^3

Take the third square root

5 = a

The length of each edge is 5 inches

**Answer:**

So the length of the edge of a cube with a volume of 125 is 5 inches

**Step-by-step explanation:**

All the edges of a cube have the same length, and the volume of a cube is the length of an edge taken to the third power.

So if we take the edge of the cube to be of length x, then:

Volume=x3

125=x3

5=x

**Answer:**

7.28

**Step-by-step explanation:**

Consider the attachment. There, we have identified a point C that makes ABC a right triangle with the right angle at C.

The Pythagorean theorem gives you the relationship between side lengths of a right triangle. The square of the hypotenuse (longest side) is equal to the sum of the squares of the other two sides.

AB² = AC² +BC²

We can count grid squares to find the lengths of AC and BC. They are 2 units and 7 units, respectively. This means ...

AB² = 2² +7²

AB² = 2·2 +7·7 = 4 +49 = 53

When we know the square, we can find what it is the square of by taking the square root. Generally, a calculator is required for this.

AB = √53 ≈ 7.2801099

When we round this number to two decimal places (the nearest hundredth), we get ...

** AB ≈ 7.28 . . . units**

_____

*Additional comments*

You will notice that the length AC in the diagram is the difference of the x-coordinates of points A and B. Similarly, the length BC in the diagram is the difference of y-coordinates. Then the square AB² is the sum of the squares of these differences. The length AB is the square root of that sum.

In general, this is how you find the length of a line segment from its end point coordinates.

So

3.2187 / 10km = 0.3218 hours
