Answer:

1/5

1/3

Step-by-step explanation:

For the first problem:

5/7 of ... is 1/7

so

5/7 of x is equal to 1/7

so

(5/7)x = (1/7)

so

x = (1/7)/(5/7)

so

x = 1/5

For the second problem:

5/7 of ... is 5/21

so

5/7 of x is equal to 5/21

so

(5/7)x = (5/21)

so

x = (5/21)/(5/7)

so

x = 1/3

Answer:

Step-by-step explanation:

Combine like terms:

-4x - 9x = (-4 - 9)x = -13x

4x - (-9x) = 4x + 9x = (4 + 9)x = 13x

-4x + 9x = (-4 + 9)x = 5x

4x - 9x = (4 - 9)x = -5x

Answer:

1.11

Step-by-step explanation:

The Slope is defined as the rate of change.

In this case,

Slope = -200+100/-180+90

         = -100/-90

         = 10/9

         = 1.11

Answer: The evaluated answer is 8. The coefficient is 6. The variable is y. The constant is 5.

Step-by-step explanation for the evaluated answer: Just substitute 1/2 for y. You should get 6x1/2+5. Then, multiply the 6 and the 1/2 and you should get 6/2+5. 6/2 can be simplified to 3 and then you just need to add the five to get 3+5=8. S your final answer should be 8. Hope this helps!

Answer:

-14

Step-by-step explanation:

Answer:

-14, fourth choice

Step-by-step explanation:

absolute value is represented with this |x|, the 2 lines

The absolute value for a real number, in this case -14, is the non-negative value without regard to its sign. So the absolute value of -5 would be 5, and the absolute value of 7 would still be 7

In this case there's no 14, so u can choose -14

Answer:

the equation x - 18 = 4(x - 18)

Step-by-step explanation:

x - 18 = 4x - 72

x - 4x = - 72 + 18

- 3x = - 54

x = 54/3

x = 18

Answer:D

Step-by-step explanation:

I just did the quiz and passed !

Option D is correct  (x, y) → (2.5x, 2.5y).

A pair of numbers called coordinates are used to locate a point or a form in a two-dimensional plane. The x-coordinate and the y-coordinate are two numbers that define a point's location on a 2D plane.

Given, Quadrilateral ABCD was dilated with the origin as the center of dilation to create quadrilateral EFGH on the graph below.

Since Scale factor:

A scale factor is defined as the ratio between the scale of a given original object and a new object, which is its representation but of a different size (bigger or smaller).

In our case,

A dilation of 2.5 because side AB is 4 units and EF is 10 units and if you divide 10/4 will get you with your scale factor.

thus, Scale factor is 2.5

Therefore,  best represents the dilation that was applied to quadrilateral ABCD to create quadrilateral EFGH is D. (x, y) → (2.5x, 2.5y)

C. (x, y) → (0.4x, 0.4y)

D. (x, y) → (2.5x, 2.5y)

Answer:

c

Step-by-step explanation:

because a proportional relationship can be thought of as one is always the same then gets times by the other or in this case 4 by x

Options A and C have a proportional relationship.

Given that, the total amount of toys a child earns when he earns 2 toys a week for w weeks.

Proportional relationships are relationships between two variables where their ratios are equivalent. Another way to think about them is that, in a proportional relationship, one variable is always a constant value times the other. That constant is known as the "constant of proportionality".

A) Let the total number of toys be x

So, x=2w

B) Let the total amount a taxi driver earns be y

So, y=3+m

C) Total cost of buying x avocados be p

So, p=4x

D) Let the total amount a Gardner earns be c

So, c=10+15r

Therefore, options A and C have a proportional relationship.

The value of the stock when Mateo’s aunt bought it was $150.

Multiplication is the mathematical operation that is used to determine the product of two or more numbers. If an event can occur in m different ways and if following it, a second event can occur in n different ways, then the two events in succession can occur in m × n different ways.

We need to find the value of the stock when Mateo’s aunt bought it.

Given that the value of the stock increased by 80%. Its value is now $270.

The stock has increased 80% thus it is now worth 180%.

Then Divide by 180;

$270/180 = $1.50

Now find 100% then Multiply by 100;

$1.50 X 100 = $150

The value of the stock when Mateo’s aunt bought it was $150.

Answer:

The answer is D. k=5

Step-by-step explanation:

The constant of proportionality is just the rate the x increases or decreases at.  The x is increasing by 5 over time so the COP or rate is 5.

Answer:

The answer is D: K=5

Step-by-step explanation:

The constant of proportionality is the ratio between two directly proportional quantities. Two quantities are directly proportional when they increase and decrease at the same rate. The constant of proportionality k is given by k=y/x where y and x are two quantities that are directly proportional to each other.

So, what you do is that you get the first number, which is 5/25. Simplify it and divided to get it as low as possible, if you do that, you would get 1/5 and 1/5 can also mean 5/1 in these situations. So your basic answer is 5.
