29/40 as a decimal would be .725 because you would have to divide 29 by 40 to get the answer.

2(6)-2x=3 CN someone answer? Use distributive property

Mandarinka [93]

Answer:

I think this is what you want:

2(6)-2x=3

We then see that 2(6) and 2(x) have two in common as a "coefficient" you could say, so we distribute and put parentheses around it.

2(6-x)=3

6-x=3/2

-x=-9/2

x=9/2

Elias and Niko are polishing the silver at the heritage museum.Elias could polish all the silver himself in 40 minutes.That task

irina1246 [14]

Let x be the time it takes Elias and Niko to polish the silver working together. If Elias works alone, he could polish all the silver himself in 40 minutes. Then, in 1 minute, he will make $\frac{1}{40}$ of the total work. If the same analysis is applied Niko, in 1 minute, will make $\frac{1}{50}$ of the total work.

Working together Elias and Niko will need x minutes to make all the work. Then, in 1 minute, they will make $\frac{1}{x}$ of the total work. So, the fraction of the total work they make in 1 minute is given by this equation:

$\frac{1}{x}=\frac{1}{40}+\frac{1}{50} \\ \\ \frac{1}{x}=\frac{50+40}{2000} \\ \\ x=\frac{2000}{90} \\ \\ \boxed{x=22.22 minutes}$

We call a number a descending number if each digit is strictly smaller than the digit that comes before it. For example, $863$ i

Mnenie [13.5K]

There are 120 of 3-digit descending numbers in total.

There is just one three-digit number that is a falling number if 2 is in the hundreds position, and that number is 210.

There are three such descending numbers if the number three is in the hundreds location.

321

Six descending numbers are available if 4 is in the hundreds place.

410

We have 10 descending numbers if the number five is in the hundreds location.

The current totals are: 1, 3, 6, and 10.

A +2 jump occurs from 1 to 3.

There is a +3 jump from 3 to 6.

From 6 to 10, there is a +4 jump.

Since there are 15 descending numbers and 6 is the hundreds digit, they are as follows: 610 620 621 630 631 632 640 641 642 643 650 651 652 653 654

Also included are the descending numbers 15+6 = 21 with the hundreds digit 7; 21+7 = 28 with the hundreds digit 8; and 28+8 = 36 with the hundreds digit 9.

They are 1,3,6,10,15,21,28, and 36.

1+3+6+10+15+21+28+36.

Equals 120 when added together.

Thus, there are 120 of 3-digit descending numbers in total.
