Answer:19x

Step-by-step explanation:

Take x as the value of pennies

If there are twice as many quarters as pennies then the explanation should be

Pennies =x

Quarters =2x

If there are 4 times as many nickels as pennies then the explanation is

Pennies =x

Nickels =4x

If there are 5 times as many dimes as nickels then the explanation is

Nickels =4x

Dimes=20x

So the values of them all is

Pennies =x

Nickels =4x

Dimes =20x

Quarters =2x

So to get how many more dimes does the child have than quarters you subtract

20x-2x=19x

Carla packed this box with 1 centimeter cubes what is the volume of the box
shusha [124]

Answer: 60\ cm^3

Step-by-step explanation:

<h3> The complete exercise is attached.</h3>

You can observe in the picture attached that the box is a rectangular prism.

The volume of a rectangular prism can be found with this formula:

V=lwh

Where "l" is the length, "w" is the width and "h" is the height.

You know that the lenght of each side of those cubes is 1 centimeter. Therefore, you can multiply the number of cubes on each side of the box by 1 centimeter in order to find the lenght, the width and the height of the box:

 l=(4)(1\ cm)=4\ cm\\\\w=(3)(1\ cm)=3\ cm\\\\h=(5)(1\ cm)=5\ cm

Now you can substitute the lenght, the width and the height of the box into the formula shown at the beginning of the explanation:

V=(4\ cm)(3\ cm)(5\ cm)

Finally, evaluating, you get that the volume of the box is:

V=60\ cm^3

If 10x + 2 = 7, what is the value of 2x?
Julli [10]

For this case we have the following equation:

10x + 2 = 7

From here, we clear the value of x.

We have then:

10x = 7-2\\10x = 5\\x = \frac {5} {10}\\x = \frac {1} {2}

Then, we look for the value of 2x. We have then:

2x = 2 \frac {1} {2}\\2x = \frac {2} {2}\\2x = 1

Answer:

The value of 2x is given by:

2x = 1
