Let the number be n.

Then 3n+5 = n+40
Combining like terms, we get

2n = 35, and so n = 35/7, or 17 1/2.

Simplify: 4^ sqrt 400/ 4^ sqrt 5 SHOW WORK

USPshnik [31]

Given

The equation is in the form

$=\frac{4^{\sqrt{400}}}{4^{\sqrt{5}}}$

Simplify the above equation

To proof

As given in the question the equation is written in the form

$=\frac{4^{\sqrt{400}}}{4^{\sqrt{5}}}$

By using the exponent property

when you divide powers with the same base you just have to subtract the exponents. i.e

$\frac{y^{a}}{y^{b}} = y^{a-b}$

y is not equal to zero.

Now apply this property to the above equation

$=4^{\sqrt{400}- \sqrt{5}}$

$\sqrt{400} = 20$

now put this in the above equation

we get

$=4^{20- \sqrt{5}}$

Hence proved

Answer:

826.8 hours

Step-by-step explanation:

Given data

Lenght of video= 234minutes

number of times watched= 212 times

Based on the information given, we can estimate the number of hours spent watching the video

=234*212

=49608 minutes

in hours

=49608/60

=826.8 hours

in days

=826.8/24

=34.45 days

There are 31 coins of dimes and quarters. If the number of dimes is 5 more than the number of quarters, how many quarters are th

emmasim [6.3K]

Answer:

13 Quarters and 18 Dimes

Step-by-step explanation:

Let D and Q stand for the numbers of Dimes(D) and Quarters(Q). Give x and y a break, and make it easier to remember which is which.

D + Q = 31

D = Q + 5

Therefore:

D + Q = 31

(Q+5) + Q = 31

2Q + 5 = 31

2Q = 26

Q = 13

Then D = (13+5) or 18

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

Check:

D + Q = 31 ?

18 + 13 = 31 YES

----------------------

D = Q + 5 ?

18 = 13 + 5 YES

Answer:

Step-by-step explanation:

First try to eliminate answers.

You have to work between 30 and 40 hours to get 1565.

It's not A or B.

Now, you can see that the choices are 31, and 35

1565 is only 15 more than 1550.

It's 31.
