Answer:

1.

n=11

2.

n =  \sqrt[3]{9}

Step-by-step explanation:

Question 1:

The given equation is:

- 28 =  - 3n + 5

Subtract 5 from both sides:

- 28 - 5 = - 3n

- 33 =  - 3n

Divide boy sides by:

-3

n =  \frac{ - 33}{ - 3}  = 11

Question 2:

The given expresion is :

5 -  {n}^{3}  =  -  4

Subtract 5 from both sides

-  {n}^{3}=  - 4 - 5

This implies that;

-  {n}^{3}=  - 9

{n}^{3}=  9

n =  \sqrt[3]{9}

Ria can paint a room in 4 hours. Destiny can paint the same room in 6 hours. How long would it take Ria and Destiny to paint the
Lerok [7]

Time taken by Ria to paint a room = 4 hours

Time taken by Destiny to paint a room = 6 hours

If they work together, they complete 1 job. So,

\frac{1x}{4}+\frac{1x}{6}=1

The LCD of 4 and 6 is 12

\frac{3x+2x}{12}=1

\frac{5x}{12}=1

5x=12

x=\frac{12}{5}

Hence, both of them can paint the room in \frac{12}{5} hours or 2.4 hours.
