fgiga [73]

Answer:

Conversion a mixed number 16 3

8

to a improper fraction: 16 3/8 = 16 3

8

= 16 · 8 + 3

8

= 128 + 3

8

= 131

8

To find new numerator:

a) Multiply the whole number 16 by the denominator 8. Whole number 16 equally 16 * 8

8

= 128

8

b) Add the answer from previous step 128 to the numerator 3. New numerator is 128 + 3 = 131

c) Write previous answer (new numerator 131) over the denominator 8.

Sixteen and three eighths is one hundred thirty-one eighths

Conversion a mixed number 9 5

8

to a improper fraction: 9 5/8 = 9 5

8

= 9 · 8 + 5

8

= 72 + 5

8

= 77

8

To find new numerator:

a) Multiply the whole number 9 by the denominator 8. Whole number 9 equally 9 * 8

8

= 72

8

b) Add the answer from previous step 72 to the numerator 5. New numerator is 72 + 5 = 77

c) Write previous answer (new numerator 77) over the denominator 8.

Nine and five eighths is seventy-seven eighths

Subtract: 131

8

- 77

8

= 131 - 77

8

= 54

8

= 2 · 27

2 · 4

= 27

4

The common denominator you can calculate as the least common multiple of the both denominators - LCM(8, 8) = 8. Cancelling by a common factor of 2 gives 27

4

.

In words - one hundred thirty-one eighths minus seventy-seven eighths = twenty-seven quarters.

Answer:

The slope is -50. The slope means that the amount of money in the account is decreasing at a rate of  $50 every week.

Step-by-step explanation:

Given coordinates are (4,2400)\ and\ (12,2000)

We need to find the slope of the graph, and explain what does slope means for this graph.

The formula for computing slope (m) is  

m=\frac{y_2-y_1}{x_2-x_1}

Where (x_1.y_1) and (x_2,y_2) are the point on the line.

Let us plug points (4,2400)\ and\ (12,2000) in the equation

m=\frac{2000-2400}{12-4}\\ \\m=\frac{-400}{8}\\\\m=-50

Here, the negative sign of slope (m) represents that the value of the function (budget) is decreasing, with an increase in time (week).

The slope is -50. The slope means that the amount of money in the account is decreasing at a rate of  $50 every week.
