find a two-digit number such that three times the tens digit is 2 less than the unit's digit and twice the number is 20 greater than the number obtained by reversing the digits.

Answers

Let's name these two digits as a (tens digit) and b (units digit) and then rephrase the problem statement using a and b.

The part of the sentence "three times the tens digit is 2 less than twice the units digits" translates into:

3a = 2b - 2

Considering that both a and b have to be integer numbers less than 10 and that a will have to be an even number

(since 2b - 2 is always even and for 3a to be even, a will have to be even),

the only possible options that will satisfy this equation are: 47 and 24.

The second part of the problem statement does not make much sense.

What exactly is twice the number obtained by reversing the digits?

In case of 47, twice the number obtained by reversing the digits is 2*74 = 148.

In case of 24, twice the number obtained by reversing the digits is 2*42 = 84.

in a classroom, 1/6 of the students are wearing blue shirts and 2/3 are wearing white shirts. there are 36 students in the class. how many students are wearing a shirt other than blue or white?

Answers

The best thing to do here is to find out what one part is equal too, add these up and then subtract it from the original number.
As 1/6 of the students are wearing blue shirts, you need to find out what 1/6 is.
As there are 36 students, you need to divide this by 6 to get one part.
36/6=6
Therefore, there are six students wearing blue shirts.
As there are 2/3 students wearing white shirts, you need to find out what 2/3 of 36 is.
The best thing to do is to find 1/3 then double it.
To do this, divide 36 by 3.
36/3= 12
12*2= 24
Therefore, there are 24 students wearing white shirts.
As you're looking for the students that aren't wearing blue and white, you need to add the total together, and then subtract this from 36.
6+24=30
36-30= 6
Therefore, there are 6 students that are wearing shirts that aren't blue or white.
Hope this helps :)

Number of students that are wearing a shirt other than blue or white is 6 students

Order of Operations in Mathematics follow this following rule :

Parentheses
Exponents
Multiplication and Division
Addition and Subtraction

This rule is known as the PEMDAS method.

In working on a mathematical problem, we first calculate operation that is in parentheses, follow by exponentiation, then multiplication or division, and finally addition or subtraction.

Let us tackle the problem !

Given:

Total Number of Students = 36 students

¹/₆ of the students are wearing blue shirts.

$\texttt{Blue Shirt Students} = (1)/(6) * \texttt{Total Number of Students}$

$\texttt{Blue Shirt Students} = (1)/(6) * 36$

$\texttt{Blue Shirt Students} = \boxed{6}$

²/₃ of the students are wearing white shirts.

$\texttt{White Shirt Students} = (2)/(3) * \texttt{Total Number of Students}$

$\texttt{White Shirt Students} = (2)/(3) * 36$

$\texttt{White Shirt Students} = \boxed{24}$

Finally, the number of students wearing other clothes can be found in the following way:

$\texttt{Other Shirt Students} = \texttt{Total Number of Students} - \texttt{Blue Shirt Students} -\texttt{White Shirt Students}$

$\texttt{Other Shirt Students} = 36 - 6 - 24$

$\texttt{Other Shirt Students} = 36 - 30$

$\texttt{Other Shirt Students} = \boxed{6}$

3 + j / 11 = 2

j =__________

Answers

j would equal -11
first subtract 3 so 2 is -1
then divide -1 by 11
so j=-11

This is how you solve it:

3 + j / 11 = 2

3 + j = 2 × 11

3 + j = 22

j = 22 - 3

j = 19

Now you could check your answer by substituting the value of j :

3 + j / 11 = 2

3 + 19 / 11 = 2

22/11 = 2

2 = 2

What is the area of a rectangle with the height of 25mm, and the length of 12mm? After you get the product, turn it into feet.

Answers

Area = (length) x (width) = (25mm x 12mm) = 300 square millimeters

You can't convert 'square millimeters' to feet. One is a unit of area,
but the other is a unit of length.

You can convert square millimeters to square feet, though.

(300 mm²) x (1 ft / 304.8 mm)² = 0.00323 square foot (rounded)

300 feet is the answer
