Answer:

3. \frac{1}{12}

4. \frac{22}{3}

5. \frac{5}{42}

8. \frac{8}{63}

9. -\frac{7}{54}

10. -\frac{3}{16}

Step-by-step explanation:

3.

\frac{-6}{8} *\frac{1}{-9} =\frac{-6}{-72}

ahora simplifica, un numero negativo dividido por otro numero negativo se convierte en positivo. Los dos nu$meros se pueden simplificar por 6

\frac{1}{12}

4.

\frac{11}{3}*\frac{4}{2} =\frac{44}{6}

ahora simplifica, los dos nu$meros se pueden simplificar por 2

\frac{22}{3}

5.

\frac{5}{-3}*\frac{-2}{7}* \frac{1}{4} =\frac{-10}{-84}

ahora simplifica, un numero negativo dividido por otro numero negativo se convierte en positivo. Los dos nu$meros se pueden simplificar por 2

\frac{5}{42}

8.

\frac{20}{-5}*\frac{1}{-9}* \frac{-2}{-7} =\frac{-40}{-315}

ahora simplifica, un numero multiplicado por otro negativo se convierte en positivo. Un numero negativo dividido por otro numero negativo se convierte en positivo. Los dos nu$meros se pueden simplificar por 5

\frac{8}{63}

9.

\frac{2}{3}*\frac{-7}{-9}* \frac{-1}{4} =\frac{14}{-108}

ahora simplifica, un numero multiplicado por otro negativo se convierte en positivo. Un numero positivo dividido por un numero negativo se convierte en negativo. Los dos nu$meros se pueden simplificar por 2

-\frac{7}{54}

10.

\frac{9}{-12}*\frac{-4}{16} =\frac{-36}{-192}

ahora simplifica, un numero negativo dividido por otro numero negativo se convierte en positivo. Los dos nu$meros se pueden simplificar por 12

-\frac{3}{16}

Espero y te ayude esto! (:

Help with b please I don’t understand it
galben [10]

Answer:

This is a 25% decrease

Step-by-step explanation:

percent change = (old - new)/old * 100 %

The new price is 15

The old price is 20

Since the new price is less than the old price, it is a decrease

percent change = (20-15)/20 * 100 %

                           = 5/20 * 100%

                            =.25 * 100%

                             = 25%

This is a 25% decrease

17. Find m2 USW if m_ USW = 7x - 34 and m2 TSR = 4x + 29.​
SVEN [57.7K]

Answer:

Step-by-step explanation:

Find the diagram attached. From the diagram, we can see that;

<USW = <TSR (vertically opposite angles)

Given

<USW = 7x-34

<TSR = 4x+29

Equate

7x-34 = 4x+29

7x-4x = 29+34

3x = 63

x = 63/3

x = 21°

Find <USW

<USW =7x-34

<USW =7(21)-34

<USW = 147-34

<USW = 113°

Hence the measure of <USW is 113°
