Answer:

  x = -3

Step-by-step explanation:

Undo the addition of -6 by adding the opposite of that to both sides of the equation.

  x + (-6) +(+6) = (-9) +(+6)

  x -6 +6 = -9 +6

  x = -3

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%.

Answer:

  Oscar

Step-by-step explanation:

On the face of it, you can see that the number of kilometers representing a given distance is greater than the number of miles. (152 > 95)

This means the constant of proportionality (a) in the equation ...

  k = am

must be greater than 1. You can find its value by solving this equation for 'a' and using the table entries for k and m:

  a = k/m = 152/95 = 8/5 = 1.6

The correct relation is ...

[tex]2.6\frac{feet}{step}[/tex] or 2.6 ft/step

Step-by-step explanation:

In order to find the average number of feet traveled per step, divide the total number of feet traveled by the total number of steps taken:

[tex]\frac{13 feet}{5 steps}=\frac{13}{5}\frac{feet}{step}=2.6\frac{feet}{step}[/tex]

Therefore, for each step taken 2.6 feet are traveled (on average). We can say this as 2.6 feet per step or 2.6 ft/step.

Answer: Third Choice. (2, 0)

Step-by-step explanation:

STEP ONE: Look over the given choice.

When the value of y is 0, the value of x would be the x-intercept.

The given choice are the following:

As we can see from the choices, the first two do not have the value of y as 0, therefore, they can be automatically neglected. Then, we are left with two choices left.

STEP TWO: Substitute the remaining values into the given equation

Given point = (2, 0)

3y + 4x = 8

3 (0) + 4 (2) = 8

0 + 8 = 8

8 = 8 [tex]\boxed {TRUE}[/tex]

Given point = (8/3, 0)

3y + 4x = 8

3 (0) + 4 (8/3) = 8

0 + 32 / 3 = 8

32/3 ≠ 8 [tex]\boxed {FALSE}[/tex]

Therefore, the ordered pair that represents the x-intercept is (2, 0).

The number of win games are 28

Step-by-step explanation:

2x+x=42

3x=42

x=42

x=14

win=2x

=2×14

=28

The number of games the sports team won if a sports team won twice as many games as they lost is 28games

Let the amount the sports team lost be x

If the sports team won twice as many games as they lost, then the number of games won will be 2x

If the sum of games won and games lost was 42, then:

x + 2x = 42

3x = 42

Divide both sodes by 3

3x/3 = 42/3

x = 14

Amount of games won = 2(14)

Amount of games won = 28games

Hence the amount of games the sports team won is 28games

The solution of the written expression, ''The sum of a number and 3 is 6 less than twice that number'' is 9.

Here,

The written expression, ''The sum of a number and 3 is 6 less than twice that number''.

We have to solve this expression.

What is Mathematical expression?

An expression consists of one or more numbers or variables along with one more operation.

Now,

Let a number is x.

By the given written expression, we can write the mathematical expression as,

x + 3 = 2x - 6

By solving;

x + 3 = 2x - 6

3 + 6 = 2x - x

9 = x

x = 9

Answer:

a + 4(n-1)

Step-by-step explanation:

The first term is a+4, the second term is a+8, the third term is a+12, etc.

A common theme that we can notice is that we add 4 for each term. For example, the second term (t₂) equals t₁+4, the third term equals t₂+4 (as a+4+4 = a+8), and so on. Another way of writing this is that we multiply 4 by (term number - 1) and add that to a. We can write this as

4 * (n-1) + a

Answer:

2/3 quarts

Step-by-step explanation:

Paint used by 9 artists = 6 quarts

So, paint used by 1 artist if shared equally among the 9 artists

= 6 quarts/9

= 2/3 quarts

= 0.6666...... quarts

Rounding to the nearest hundredth, each artist would get approximately 0.67 quarts of paint.

To determine how many quarts of paint each artist gets when six quarts of paint are equally shared among nine artists, we can divide the total amount of paint by the number of artists. 6 quarts ÷ 9 artists = 0.6667 quarts per artist

To "equally share" means to divide or distribute something equally among a group of individuals or entities. It implies that each person or entity involved receives an equal portion or share of the item being distributed. This division ensures fairness and equal opportunities for everyone involved. The goal is to ensure that each recipient receives an equal amount or proportion of the item being shared.

Step-by-step explanation:

4. -7 = 3k - 3-7

Combine like terms

-3 = 3k-10

Add 10 to each side

-3+10 = 3k-10+10

7 = 3k

Divide each side by 3

7/3 = 3k/3

Answer:

7/3

Step-by-step explanation:

4 - 7 = 3k - 3-7

Answer:

[tex]y = -\frac{3}{7}x + 3[/tex]

Step-by-step explanation:

In order to find the equation of a line, we need to first find the slope. Slope is represented by the formula:

[tex]\frac{y_{2}-y_{1} }{x_{2} - x_{1} }[/tex]

where (x1, y1) and (x2, y2) are point on the line. In this case, we can use the points (0, 3) and (7, 0):

[tex]\frac{0-3}{7-0} = -\frac{3}{7}[/tex]

The point (0, 3) is the y-intercept, so given an equation in the form y = mx + b, 3 would be b and we already calculated the slope, which is m. We can plug these values in to get:

[tex]y = -\frac{3}{7}x + 3[/tex]

Answer:

(y+4) /2

Step-by-step explanation:

(y²-16)/(2y+6) × (y+3)/(y-4) =

(y+4)(y-4) / 2(y+3) × (y+3)/(y-4)

=> eliminate all (y-4) and (y+3)
