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:

Answer: 10

Step-by-step explanation: 7x-11=x-49

7x - 11 = x - 49 so add 11 to both sides 7x = x -60

Then 7x - x = 6 so 60/6= 10

Answer:

The difference between iPhone 11 and Spinal cord repairence is 99,300$.

Step-by-step explanation:

To be honest, this is a really weird question.  But a spinal cord injury can cost up to 100,000$ a year.  And an iPhone 11 cost around 700$.  It really just depends on what repairence the person got, but if I am wrong then I hope you the best with your question lol.  And since Alex didnt break his phone, you wouldnt count the repairs for the iPhone 11.

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:

(a) Leann is incorrect

(b) For every main dish, there are 3 sides

(c) 6 selections

Step-by-step explanation:

See attachment for complete question

Given

Main Dish: Burger (B), Chicken (C), Pasta (P)

Sides: Apple (A), Fries (F)

Solving (a): Is Leann list correct?

From the question, the list is: BA, BF, CA, CF, PA, PF, AB, FB, AC, FC, AP, FP

This list is incorrect because:

AB is the same BA, BF is the same as FB and so on

Solving (b): Number of sides for each Main dish

From the question:

[tex]Main\ dish = 2[/tex]

[tex]Sides = 3[/tex]

This implies that:

For every main dish, there are 3 sides

Solving (c): Total number of selection

In (b), we have:

[tex]Main\ dish = 2[/tex]

[tex]Sides = 3[/tex]

So: the total is:

[tex]Total = Main\ dish * Sides[/tex]

[tex]Total = 2 * 3[/tex]

[tex]Total = 6[/tex]

[tex]32.9 \div 100 = 0.329cm[/tex]

Step-by-step explanation:

When you move from m to cm you divide by 100

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:

x^2 - 4x - 3 + 28/x+4

Step-by-step explanation:

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.
