Answer:

k

Step-by-step explanation:

The constant of proportionality is the ratio between two directly proportional quantities. ... Once you know the constant of proportionality you can find an equation representing the directly proportional relationship between x and y, namely y=kx, with your specific k.

Answer as a fraction = 1/2

Answer as a decimal = 0.5

Answer as a percent = 50%

========================================

Explanation:

There are 5 blue rectangles out of 10 total. This forms the fraction 5/10 and that reduces to 1/2 after dividing both parts by 5. Therefore, the fractions 5/10 and 1/2 are the same. Notice that exactly half of the entire figure is shaded blue.

Use long division or your calculator to find that 1/2 = 0.5 which converts to 50% when you move the decimal point 2 spots to the right.

Answer:

5/10 , 0.5 , 50%

Answer:

Jeandre is correct, and they are 2 units from zero

Step-by-step explanation:

The absolute value of 2 is 2, and the absolute value of -2 is 2. Absolute value is the real number without a sign. If you put both 2s, on the number line, they would be the same length from zero. Hope this helps!

Answer:

Jeandre is correct, and they are 2 units from zero

Step-by-step explanation:

The absolute value of 2 is 2, and the absolute value of -2 is 2. Absolute value is the real number without a sign. If you put both 2s, on the number line, they would be the same length from zero. by the way absolute value means that everything will be positive, for an example - |-1| it is going to be positive one now! how you can tell it is a absolute value is cause it will have lines imbetween the number (ex - |-3|)

Answer:19

Step-by-step explanation:

The answer is 19 because you need to do 12*2 and then subtract 6. 24-6=19

Answer:

18

Step-by-step explanation:

1.) 2y -6

2 ) 2(12) - 6

3.) 24 - 6

Answer ~ 18

1.) 12 equals y so put 12 in place of y

2.) Using PEMDAS, multiply 12 × 2 which equals 24.

3.) Then you subtract 6 from 24 which equals 18.

Answer:

Answer:

It's X=2

Working out:

(left one):

2(x+3)=10

2x+6=10

2x=10-6

2x=4

x=2

Working out:

(right one):

2(x+3) must be all divided by 2 so it will be x+3 and same for 10, it will be 5 so...

x+3=5

x=5-3

x=2

Hope it helps ^---^

Answer:

31.95

Step-by-step explanation:

So first you have to identify what the mark up is which would be $9.45

Then you add that to 22.50... And idk what you mean by Round up to two decimal places when necessary.

Answer:

$31.95

Step-by-step explanation:

22.50*1.42=31.95

Answer: $9.99

Step-by-step explanation:

2=$4

2/2=1

4/2=2

$2+$8 =10$

Answer:

D.$9.95

Step-by-step explanation:

If you divide the cost of 2 pairs of socks in half which is $3.98 you would get $1.99 which is the cost of 1 pair of socks and then you would multiply $1.99 by 5 to get $9.95 which would be the cost of 5 pairs of socks.

Answer:

12 inch so total inches = 7*12 + 1 = 85 inches 1 inch = 2.54 cm 85 inches = 85 * 2.54 = 215

Answer:

6(12+8)

Step-by-step explanation:

the word 'times' would indicate the multiplication of 2 numbers

the word 'sum' would indicate the addition of 2 numbers. in this case, 12 + 8 would be placed in parenthesis

hope this helps!! :)

Answer:

The answer is either 1.5 or 0.667

Step-by-step explanation:

x2+3x-9=0

x2+3x=9

6x=9

x=1.5

or

x=667

the value of 'h' used to solve the equation by completing the square method is [tex]\frac{9}{4}[/tex]

Given :

An equation and the first step in its solution are shown.

Equation: [tex]x^2 + 3x -9 = 0[/tex]

Step 1: [tex]x^2 + 3x + h = 9 + h[/tex]

In completing the square method , we take the coefficient of x  and divide it by 2  and then square it

coefficient of x is 3

divide it by 2 , so we get [tex]\frac{3}{2}[/tex]

Then we square it [tex](\frac{3}{2} )^2\\\frac{9}{4}[/tex]

Then we add it on both sides of the equation

[tex]x^2 + 3x + \frac{9}{4} = 9 + \frac{9}{4}[/tex]

So, the value of 'h' used to solve the equation by completing the square method is [tex]\frac{9}{4}[/tex]
