Answer:

Penny:

3/100 ; 0.03

Dimes :

7/10 ; 0.7

Amount to add to make whole number = $0.23

Step-by-step explanation:

Recall:

100 pennies = $1

1 penny = 1 / 100

3 Pennies = 3 / 100 (In fraction)

3 pennies = 0.03

10 dime = $1

1 dime = 10 /100 = 1/ 10

7 dimes = 7/10 (fraction)

7 dimes = 0.7

To make the money in jar a whole dollar :

Amount to be added :

1 - (0.03 + 0.70)

1 - 0.73

= $0.27

ABSOLUTEEE VALUEEEE HELPP PLZ

Answer:

Last option; x < 2 and x > -1

Step-by-step explanation:

1. We know 2x − 1 < 3 and 2x − 1 > −3, so let's solve both of these inequalities.

2. (Solving for 1st condition)

Step 1: Add 1 to both sides.

$2x - 1 + 1 < 3 + 1$
$2x < 4$

Step 2: Divide both sides by 2.

$\frac{2x}{2} < \frac{4}{2}$
$x < 2$

3. (Solving for 2nd condition)

Step 1: Add 1 to both sides.

$2x - 1 + 1 > -3 + 1$
$2x > -2$

Step 2: Divide both sides by 2.

$\frac{2x}{2} > \frac{-2}{2}$
$x > -1$

4. Now, we know that the value of x is greater than -1 but less than 2, and we can represent it on a number line like this:

1. Refer to the equation 3x − 4y = 12. (a) Create a table of values for at least 4 points.

Zinaida [17]

Answer: THE TABLE OF VALUES IS ATTACHED.

Step-by-step explanation:

Given the following equation:

$3x-4y = 12$

You can solve for the variable "y":

$3x-4y = 12\\\\-4y=-3x+12\\\\y=\frac{3}{4}x-3$

Now you can give values to "x" and substitute each into the equation to find the corresponding value of "y".

For $x=-1$ :

$y=\frac{3}{4}(-1)-3=-3.75$

For $x=0$ :

$y=\frac{3}{4}(0)-3=-3$

For $x=1$ :

$y=\frac{3}{4}(1)-3=-2.25$

For $x=2$ :

$y=\frac{3}{4}(2)-3=-1.5$

With this values you can make the table shown attached.

Help me please please please it’s due tonight!!!!!!!!!!!

Answer:

A. (4, 18)

Step-by-step explanation:

The "y" coordinate of the midpoint will be equal to the average of the y coordinates of the endpoints, and the x coordinate of the midpoint will be equal to the average of the x coordinates of the endpoints, and so we get that...

The x coordinate of the midpoint = (5 + 3) / 2 = 8 / 2 = 4

The y coordinate of the midpoint = (21 + 15) / 2 = 36 / 2 = 18

So the right answer is A (4, 18)
