[tex]4\frac{1}{4} - 2\frac{7}{8} = 1\frac{3}{8}[/tex]

Step-by-step explanation:

Given

[tex]4\frac{1}{4} - 2\frac{7}{8}[/tex] --- proper representation of the question

Required

Evaluate

Convert numbers to improper fractions

[tex]4\frac{1}{4} - 2\frac{7}{8} = \frac{17}{4} - \frac{23}{8}[/tex]

Take LCM

[tex]4\frac{1}{4} - 2\frac{7}{8} = \frac{34 - 23}{8}[/tex]

[tex]4\frac{1}{4} - 2\frac{7}{8} = \frac{11}{8}[/tex]

Convert to improper fraction

[tex]4\frac{1}{4} - 2\frac{7}{8} = 1\frac{3}{8}[/tex]

Answer:

No, the student is not correct. The correct expression is 9(n+13).

Step-by-step explanation:

"9 times the sum of a number and 13" means you must multiply 9 by the sum, not just by the number. 9n + 13 would be "the sum of 9 times a number and 13." Slightly different wording.

Answer:

Sample Response: The student is not correct. He should use parentheses like this 9(n+13). Without the parentheses, it means nine times n plus 13, but should be the sum of n plus 13 multiplied by 9.

Answer:

|-3| > 1

Step-by-step explanation:

Well |-3| = 3

3 > 1

1 < 3

(you can replace 3 for |-3| in those up there^)

Answer:

ecall that 6 + 6 + 6 = 6 × 3

Instead of adding 6 three times, you can multiply 6 by 3 and get 18, the same answer.

Similarly,

6 + 6 + 6 + 6 + 6 + 6 + 6 = 6 × 7 = 42

Still by the same token,

2 + 2 + 2 + 2 = 2 × 4

In algebra, 2 × 4 can be written as (2)(4)

You can think of this as four groups of 2.

This situation is shown in the number line below.

You basically start at 0 and count by 2's until you have put four 2's on the number line. You end up at 8 and 8 is positive.

Answer:

40.4%

Step-by-step explanation:

Given data

Initial depth= 5feet

Final depth= 5-3.2+6.6= 8.4feet

Hence the percent change

% change= FInal-initial/final*100

% change= 8.4-5/8.4*100

% change= 3.4/8.4*100

% change= 0.404*100

% change=40.4%

Hence the percent change is 40.4%

Percentage change between two measurement is the proportion of

change between the measurement expressed as a percentage.

The percentage change in the river depth in in 1848 is 106.25%

Reasons:

The given parameters are;

The depth of the river in the year 1846 = 5 feet

In the year 1847, the depth = 3.2 feet

In 1848 the depth = 6.6 feet

[tex]\displaystyle Percentage \ change = \mathbf{ \frac{Current \ depth - Previous \ depth}{Previous \ depth}}[/tex]

Which gives;

[tex]\displaystyle Percentage \ change = \frac{6.6 -3.2}{3.2} \times 100 = \mathbf{106.25 \%}[/tex]

The percentage change in the river depth in the current period = 106.25%

Answer:

u = 66°

v = 38°

Step-by-step explanation:

If this is a parallelogram:

u = 66°, angle opposite 3v = 3v

All four interior angles total 360°

Then:

3v + 3v + 66° + 66° = 360°

combine like terms:

6v = 228°

v = 38°

Answer:

50 pencils

Step-by-step explanation:

2.19/12 = .18

3.99/40 = .09975

4.75/50 = .095

10/100 = .10

Although with mark-up to the hundredths place, there wouldn't be a logical difference is stores...

Answer:

50 for $4.75

Step-by-step explanation:

First step is to determine the unit cost of each pencil:

price of pack / number of units = cost per pencil

1. $2.19 / 12 = $0.1825

2. $3.99 / 40 = $0.09975

3. $4.75/ 50 = $0.095

4. $10 / 100 = $0.10

The correct answer is $4.75 for 50 pencils because it is the lowest per unit cost.

Answer:

x=5

Step-by-step explanation:

The x - intercept of the graph of the expression is (5, 0).

We have the following expression -

- 4x = - 20

We have to find the x - intercept of the graph of this expression.

The Slope - intercept form of the equation of a straight line is as follows-

y = mx + c

where -

m - slope of line

c - intercept of line on y - axis.

According to the question -

- 4x = - 20

x = 5

Hence, the x - intercept of the graph of the expression is (5, 0). Refer the graph attached in the end.

Answer:

y = 3/2x + 7/2

Step-by-step explanation:

First, you need to find the slope.

y2 - y1 / x2 - x1

= 5 - 8 / 1 - 3

= 3/2

The slope is 3/2x.

To find the y-intercept, plug any one of the coordinates into the equation, which is y = 3/2x + b

y = 3/2x + b

8 = 3/2(3) + b

8 = 9/2 + b

7/2 = b

The equation y = 3/2x + 7/2.

Answer:

  C  3x +1 = y

Step-by-step explanation:

x-values increase by 1 from row to row.

y-values increase by 3 from row to row.

The slope of the linear function is the ratio of the y-increase to the x-increase:

  m = ∆y/∆x = 3/1 = 3

The only offered choice with an x-coefficient of 3 is ...

  C  3x +1 = y

If you check this against the table entries, you find it fits.

  3(1) +1 = 4

  3(2) +1 = 7

and so on.
