6 0

Answer:

1/6

Step-by-step explanation:

First you make the denominator on the fractions the same

3 * 2 = 6

Multiply the number the same for the numerator

3 * 1 = 3

so the fraction is 3/6 since 3/6 = 1/2

4/6 - 3/6 = 1/6

she has 1/6 pipe left

Complete these ordered pairs for this equation. (0, ), (-2, ), (4, ) y=2x

quester [9]

Answer:

Part 1) The ordered pair is (0,0)

Part 2) The ordered pair is (-2,-4)

Part 3) The ordered pair is (4,8)

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form $y/x=k$ or $y=kx$

In a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin

In this problem we have a direct variation

$y=2x$

Complete the ordered pairs

Part 1) we have (0,?)

For x=0

Substitute in the equation and solve for y

$y=2(0)=0$

therefore

The ordered pair is (0,0)

Part 2) we have (-2,?)

For x=-2

Substitute in the equation and solve for y

$y=2(-2)=-4$

therefore

The ordered pair is (-2,-4)

Part 3) we have (4,?)

For x=4

Substitute in the equation and solve for y

$y=2(4)=8$

therefore

The ordered pair is (4,8)

If Dominik completes a project by himself, it will take him 8 hours. Working with Katarina, it will take them 5 hours. If they w

Marysya12 [62]

The main formula we use here is Work=Rate*Time,

1. The rate (speed of working) of Dominik is

$r_D=1project/8hours= \frac{1}{8}(prj/h)$

2. Let the the rate of Katarina be $r_K=x(prj/h)$

Together they have a rate of $r_D_K$ equal to $\frac{1}{8}+x$ (project per hour)

so $(\frac{1}{8}+x) ( \frac{proj}{hr})*5(hr)=1(proj)$

simplify the units:

$(\frac{1}{8}+x) *5=1$

$\frac{1}{8}+x = \frac{1}{5}$

$x= \frac{1}{5}- \frac{1}{8}= \frac{8-5}{40}= \frac{3}{40}$

so the rate of Katarina is 3/40 (proj per hour)

Now, the rate of Dominik was 1/8 (pr/hr)=5/40 (pr/hr)

In 5 hours Dominik complets 5*5/40=25/40 of the project

Katarina completes 5*3/40=15/40 of the project.
