$\frac{21-x}{x}=\frac{1}{2} \\\\2(21-x)=x\\\\42-2x=x\\\\42=x+2x\\\\3x=42\\\\x=14$

A person bought a safe which can be unlocked by entering a 2-digit

just olya [345]

39 number is the secret code as the unlock code for the safe.

According to the statement

we have given that a some numbers as a code and we have to find the correct code after applying the given conditions.

So, For this purpose

The given number set is

5 17 29 22 11 26 27 35 39 41

So,

A. One condition : It is an odd number

so, the number set become

5 17 29 11 27 35 39 41

And

B. Second condition : It is greater than 20

so, the number set become

29 27 35 39 41

And

C. Third condition : It is smaller than 40

so, the number set become

29 27 35 39

And

D. Fourth condition : It is not a prime number

so, the number set become

27 35 39

And

E. Fifth condition : It has 13 as one of its factors

so, the number set become

39.

So, 39 number is the secret code as the unlock code for the safe.

Marne Shia walked 3/8 of a mile in 3/5 of an hour. What equation can be used to calculate her unit rate in miles per hour?

Dafna11 [192]

Answer:

speed = (3/8 mi)/(3/5 h)

Step-by-step explanation:

... speed = distance/time

Fill in the given values:

... speed = (3/8 mi)/(3/5 h)

_____

<em>Comment on units</em>

You can use the units to provide both guidance and assurance. You know speed is generally expressed in <em>miles per hour</em>. If you consider "per" to mean "divided by", this expression of units tells you speed is calculated by dividing miles by hours.

If you leave the units with the numbers, as we have above, they enter into the calculation the same way any variable might. You can do the arithemetic with the numbers, and you can indicate the arithmetic with the units (just as you would with any variables). Here, the result of evaluating the equation would be ...

$\displaystyle\frac{\frac{3}{8}\,\text{mi}}{\frac{3}{5}\,\text{h}}=\frac{\frac{3}{8}}{\frac{3}{5}}\,\frac{\text{mi}}{\text{h}}=\frac{5}{8}\,\text{mi/h}$

The fact that the units come out mi/h (the units of speed) provides assurance that you probably did the math correctly.
