Answer:

John got 13 questions right and 2 questions wrong.

Step-by-step explanation:

15 questions right equals 100%.

100 {divided by} 15 = % for each question right

Each question is worth (100 diveded by 15) 6.7%.

84% {diveded by} 6.7% = 12.5

100% - 84% = 16%

16% {divided by} 6.7% = 2.38

Because 12.5 has a higher dicimle value than 2.38 and when the amount he got right is added to the amount he got wrong it needs to equal 15, 12.5 becomes 13 and 2.38 becomes 2.

Answer:

[tex]\frac{n}{15} =\frac{84}{100}[/tex]

[tex]n = \frac{21}{25}*5[/tex]

[tex]n = \frac{21*15}{25}[/tex]

[tex]n = \frac{315}{25}[/tex]

[tex]n = \frac{63}{5} or 12.6[/tex]

Answer:

(y+7)=5/6(x+6)

Step-by-step explanation:

For this problem we need to use Point-Slope Form to write an equation.

We already have the point, (-6,-7), so all we need now is the slope, which we know is perpendicular to the line 6x+5y=30.

First, let's find the slope of 6x+5y=30 by converting it into Slope-Intercept Form, which is y=mx+b. m is the slope.

6x+5y=30

5y=-6x+30

y=-6/5x+6

So the slope of this line is -6/5, but we need the slope of the line is perpendicular to this line.

When a line is perpendicular to another, their slopes are negative reciprocals to one another, or opposite reciprocals. For example, a line that is perpendicular to another line that has a slope of 3/4 will have a slope of -4/3. Flip the numerator and denominator to find the reciprocal and add a negative.

x

So the negative reciprocal of -6/5 is 5/6, so that is our slope.

Now we can assemble our equation, here is the Point-Slope Form:

[tex](y -y_{1}) =m(x-x_{1})[/tex]

again, m is our slope.

[tex]y_{1}[/tex] and [tex]x_{1}[/tex] represent the coordinates of the point that this line passes through, (-6, -7).

Let's plug in the y, x, and m values:

(y-(-7))=5/6(x-(-6))

Simplify:

(y+7)=5/6(x+6)

That is our final answer.

Answer:

I'll try to give u an example the best way possible

Step-by-step explanation:

1) we are going to solve this division problem (84/7).

2) Divide 8 by 7 to get 1. Place this on top of the 8 and the division sign.

3) Multiply 1 and 7 to get 7. Place this under the 8.

4) Subtract 7 from 8 to get 1.

5) Carry down the 4.

6) Divide 14 by 7 to get 2. Place this on top of the 4 and the division sign.

7) Multiply 2 by 7 to get 14.

8) Subtract 14 from 14 to get 0.

The answer is 12!

Answer:

Step-by-step explanation:

B) 9<x<5

X has to be more than 9.  9+8=17, which would be a straight line.

X has to be less than 25.  17+8=25, which would be a straight line.

Answer:

9 < x < 25

Step-by-step explanation:

The length of a side of a triangle must be greater than the difference between the lengths of the other sides and less than the sum of the lengths of other sides.

x must be greater than the difference between 17 and 8.

17 - 8 = 9

x > 9

x must be less than the sum of 17 and 8.

x < 17 + 8

x < 25

When you put the two inequalities above together, you get:

9 < x < 25

Step-by-step explanation:

5 to each players means you have 6 players and then you have 10 left for yourself

Answer:

You can hand out 5 softballs to 6 players.

Step-by-step explanation:

In order to solve this problem, you need to divide 30 balls to each player (In order to have 10 left.) 30 divided by 5 is 6, so you can only hand out 5 balls to 6 players in order to have 10 left out of 40.

Answer:

$13.75 per gallon

Step-by-step explanation:

To solve for any unit rate you use

[tex]\frac{1}{x} =\frac{5}{68.75}[/tex]

Cross multiply.

So 68.75 = 5x

Divide both sides by 5 to get x alone.

13.75 = x

Therefore 1 gallon equals $13.75

Answer:

[tex]a_{n}[/tex] = 6n - 4

Step-by-step explanation:

There is a common difference between consecutive terms in the sequence, that is

8 - 2 = 14 - 8 = 6

This indicates the sequence is arithmetic with n th term

[tex]a_{n}[/tex] = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = 2 and d = 6 , thus

[tex]a_{n}[/tex] = 2 + 6(n - 1) = 2 + 6n - 6 = 6n - 4

Thus the formula representing the sequence is

[tex]a_{n}[/tex] = 6n - 4

Answer:

(-4,3)

Step-by-step explanation:

Answer:

P = -4, 3

Step-by-step explanation:

Locate the x-axis (horizontal) location of point P, starting from zero

Point P's x-axis = -4

Now locate the y-axis (vertical) location of point P, starting from zero

Point P's y-axis = 3

Combine the two axes in a coordinate equation.

Point P = (-4, 3)

Note that zero is located at the intersection of the two axes.

Answer:

11+5x=5x+20

We move all terms to the left:

11+5x-(5x+20)=0

We get rid of parentheses

5x-5x-20+11=0

We add all the numbers together, and all the variables

-9!=0

There is no solution for this equation

Step-by-step explanation:

I saw it from Google

Answer:

C

Step-by-step explanation:

Slope intercept form equation is y=mx+b

M=Slope

Slope equation is y2-y1 over x2-x1

So -16 - 47 over 2- (-4)

-63 over 6

Divide by 3 to simplify

= -21 over 2

Keep that as your answer for slope because a mixed number can't be used for slope but an improper fraction is perfectly fine

To find b use one point given (I chose to use (2, -16)

Plug that in and your slope to find b

-16= -21/2 (2) +b

-16= -21+b

+21 +21

5=b

Now plug that in and youre done

Y= -21/2x + 5
