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.

Step-by-step explanation:

A = 10²(3.14) = 314

(293/360)(314) = 255.7 cm²

Answer:

255,56

Step-by-step explanation:

L = 293/360 x 314 = 255,56

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.

Step-by-step explanation:

let b be the number of boys

let g be the number of girls

[tex]b + g = 1908\\17g = 19b\\g = \frac{19}{17} b\\b+\frac{19}{17} b = 1908\\2\frac{2}{17}b = 1908\\b = 901\\901 + g = 1908\\g = 1007[/tex]

Answer:

20

Step-by-step explanation:

Your gonna want to do 60 divided by 3 which if you do not understand division a way to do it is to keep subtracting 60-3 until you get to 0 and count the number of times it took to get to 0 which would be 20 because also 20 times 3 equals 60.

Answer: The answer is H

Step-by-step explanation: what i did is= 60/3=20 and then 20x5 hope that helps. If not ask me a question

The value is 18.84.

An expression contains one or more terms with addition, subtraction, multiplication, and division.

We always combine the like terms in an expression when we simplify.

We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

Example:

1 + 3x + 4y = 7 is an expression.

3 + 4 is an expression.

2 x 4 + 6 x 7 – 9 is an expression.

33 + 77 – 88 is an expression.

We have,

3.14 x 6

Multiply the values.

= 18.84

Thus,

The value is 18.84.

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.

Answer:

The first choice is the answer of course

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:

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.
