$\frac{5}{n} = \frac{1.5}{1.8} \ \ \ \Leftrightarrow\ \ \ 5\cdot1.8=1.5\cdot n \ \ \ \Leftrightarrow\ \ \ 9=1.5n\ /:1.5\\\\n=6$

5/n=(3/2)/(5/5+4/5)

5/n=(3/2)/(9/5)

5/n=(3/2)*(5/9)

5/n=15/18=5/6

5/n=5/6

30/n=5

5n=30

Therefore: n=6.

Answer: Third option

Step-by-step explanation:

For this exercise it is important to remember the following:

1. By definition, the Associative property of addition states that it does not matter how you grouped the numbers, you will always obtained the same sum.

2. The rule for the Associative property of addition is the following (given three numbers "a", "b" and "c"):

$a + (b + c) = (a + b) + c$

Knowing the information shown before, you can identify in the picture attached that the option that illustrates the Associative property of addition is the third one. This is:

$(11+8)+1=11+(8+1)$

As you can notice that you will always get the same result:

$(19)+1=11+(9)\\\\20=20$

Triangle J is shown below. James drew a scaled version of Triangle J using a scale factor of 4 and labeled it

Novay_Z [31]

Answer:

The area of triangle K is 16 times greater than the area of triangle J

Step-by-step explanation:

we know that

If Triangle K is a scaled version of Triangle J

then

Triangle K and Triangle J are similar

If two triangles are similar, then the ratio of its areas is equal to the scale factor squared

Let

z -----> the scale factor

Ak ------> the area of triangle K

Aj -----> the area of triangle J

so

$z^{2}=\frac{Ak}{Aj}$

we have

$z=4$

substitute

$4^{2}=\frac{Ak}{Aj}$

$16=\frac{Ak}{Aj}$

$Ak=16Aj$

therefore

The area of triangle K is 16 times greater than the area of triangle J

Solve for x. −1.9=x/0.5

Feliz [49]

-1.9 = x/.5 given equation

multiply both sides by .5

.5(-1.9) = x/(.5) *(.5)

-.95 = x

check: -1.9 = -.95/ .5

Carissa earns $450 per week for a 40 hour work week plus $16.83 per hour for each hour of overtime after 40 hours. Write an equa

gavmur [86]

Answer:

W = 450 + 16.83V

Step-by-step explanation:

For 40 hours Carissa

earning = $450

earning for 1 hour of over time = $16.83

multiplying both side by V

earning for v hour of over time = $16.83*V = $16.83V

weekly wage(W) = earning for 40 hours + earning for V hour of over time

W = 450 + 16.83V

Thus equation will be as given below for weekly earning
