For what value of k does the equation have no solution? kx - 4 = 5x + 8

Answer:

x < -5.5

Step-by-step explanation:

2(4x + 1) < 3(2x - 3)

first, treat it like an equation

2 ( 4x + 1 ) < 3 ( 2x - 3)

distribute

8x + 2 < 6x -  9

now use inverse operations

8x + 2 < 6x - 9

    -2           -2

8x < 6x - 11

-6x   -6x

2x < -11

/2     /2

x < -5.5

Answer:

Step-by-step explanation:

The idea begin this problem is to solve for the perimeter of the square garden using the expression for perimeter which is

Perimeter of square= 4L

given that the garden wants the side of the square garden to be between 15 and 18 ft long

Say we go with a length of 16ft (you can pick any number in the range just maintain the formula for the perimeter)

perimeter= 4(16)

perimeter= 64ft

now we have to convert ft to yard

1 yard=3ft

x yard=64ft

cross multiply we have

x=64/3

x=21.33 yards

given that a yard cost $1.5, therefore 21.33 yards will cost

=21.33*1.5

=$31.99

Answer: t = 22x + 50

Step-by-step explanation:

t = total amount earned

x = hours worked

We know his friend payed $50, so that is our initial value. We don’t need hours for that one.

For his job as trainer, he earns $22 per hour but we don’t know how many hours he earned, so that is x. That is how I got the 22x.

Hope this helps! And of course, feel free to use any variables of your choice. :)

The cost of a large single chocolate is $0.25.

Given is that April and bill went to the grocery store to buy chocolate bars. April bought 4 small chocolate bars and 6 large chocolate bars and 3 large chocolate bars. April paid $16.50 and bill paid $11.25.

We can write -

4x + 6y = 16.50                               ... Eq{ 1 }

3x = 11.25                                            ... Eq{ 2 }

On solving the equation, we get -

{x} = 11.25/3

{x} = 3.75

Now, we can write -

4x + 6y = 16.50

4 x 3.75 + 6y = 16.50

6y = 16.5 - 15

6y = 1.5

y = 1.5/6

{y} = 0.25

Therefore, the cost of a large single chocolate is $0.25.

Answer:

10a - 11y

Step-by-step explanation:

3(2a - y) - 4(2y - a)

open the parenthesis

6a - 3y - 8y + 4a

combine like terms

6a + 4a - 3y - 8y

10a - 11y

Option C, 1 mile is the correct answer

The displacement is 1 mile.

Given that, Amy runs 2 miles south, then turns around and runs 3 miles north.

Displacement is the change in the position of any point or object. It has a direction and magnitude, so it is a vector quantity. It is shown with an arrow that points from the starting position to the final position.

Now, Amy runs 2 miles south from the fixed point he runs in the north direction for 3 miles.

So, the displacement=1 mile

Therefore, the displacement is 1 mile.

Answer:

x=20°

Step-by-step explanation:

(6x+2)° and (5x+22)° are vertically opposite angles, hence VOA angles are equal so

(6x+2)°=(5x+22)°

6x°+2°=5x°+22°.... collect the like terms

6x°-5x°=22°-2°

x°=20°

Answer:

2x+118=180

x=31

Step-by-step explanation:

Congruent means equal so the two missing angles are same, therefore being 2x. Add 118 to 2x since it is already known and all of that is equal to 180. Solve:

2x+118=180

2x=62

X=31

Answer:d

Step-by-step explanation:

Answer: d) +/- 2/3

Step-by-step explanation: Since x^2 is a exponent, to cancel it out you would have to square root both sides. Therefore, x is equal to +/- 2/3.

Answer:

D

Step-by-step explanation:

The answer is D which is ± 2/3.

x² = 36/81

The √36 is 6 and √81 is 9. So √(36/81) will be 2/3. However, the answer is ±2/3 because we are taking the square root so there's a possibility that the answer can be positive and negative.

An example with addition is 3x(20+5) as 20 plus 5 is still 25, and an example with subtraction is 3x(30-5), as 30 minus 5 is 25.

5. When your independent variable is qualitative, and your dependent variable variable is quantitative

Step-by-step explanation:

A bar graph is a graph that is used for the comparison of the measured values of different groups of items and are typically used for comparison of data that belong to different categories rather than for comparison of a continuous data  set, such that the categories of the data are presented in columns of a particular category along the horizontal axis, while the vertical represents the measured value for each category

Therefore, given that the independent variable is normally presented along the horizontal axis, and the dependent variable is normally presented along the vertical axis, we have that the bar chart is best suited when the independent variable is qualitative and the dependent variable is quantitative.

Answer:

The correct answer would be 5)When your independent variable is qualitative, and your dependent variable is quantitative.
