It's a simple linear equation in 'n'.  There's only one number that 'n' can be
that will make the equation a true statement.  That number is called the
'solution' to the equation.  Here's one way to find it:

You said that                       <u> -7n - 4  =  24</u>

Add  4  to each side:           -7n       =  28

Multiply each side by  -1 :    7n       =  -28

Divide each side by  7 :         <em>n        =  -4</em>

Homework is the only way for most people to learn stuff.

Hey hey hey. help pls
Firdavs [7]

Answer:

Emma spend 8 hours in homework in a week and Jared  spends 16 hours in homework in 2 weeks.

Step-by-step explanation:

Two quantities P and Q are said to be in PROPORTION if and only if for all values of P and q, we get:

\frac{P}{Q}  = k

Here, k : PROPORTIONALITY CONSTANT

Case: 1

5 hour piano practice in 1 week.

So, the piano practice in 2 weeks( 1 x 2) =   2 x  5 = 10 hours

But here, it is given to be 12 hours in 2 weeks.

Hence, NOT PROPORTIONAL.

Case 2:

70 words in 60 seconds.

So, the words typed in 210 seconds ( 60 x 3.5) =   70  x  3.5 = 240 words

But here, it is given to be 280 words in 210 seconds.

Hence, NOT PROPORTIONAL.

Case: 3

8 hour homework in 1 week.

So, the homework done in 2 weeks( 1 x 2) =   2 x 8 = 16 hours

It is given to be 16 hours in 2 weeks.

Hence,  PROPORTIONAL.

Case: 4

15 miles  in 78 minutes.

So, the distance covered in 102 minutes (78 x 1.3) =  15 x 1.3 = 19.6 miles

But here, it is given to be 17 miles in 102 minutes.

Hence, NOT PROPORTIONAL.

Case: 5

18 miles  in 45 minutes.

So, the distance covered in 55 minutes (45 x 1.2) =  18 x 1.2  = 21.6 miles

But here, it is given to be 22 miles in 55 minutes.

Hence, NOT PROPORTIONAL.

Hence, the only proportional case is Emma spend 8 hours in homework in a  week and Jared  spends 16 hours in homework in 2 weeks.

The price of a coat increased from $78 to $92. What is the price increase percentage?
svetlana [45]

Answer:

18%

Step-by-step explanation:

Percent change can be found using the following formula:

\frac{original-new}{original}*100

Original represents the initial cost where new represents the new cost.  We multiply the answer by 100 to get the percentage:

\frac{92-78}{78}*100 = 18%
