Mathematics
1 answer:

Answer:

6/5

Step-by-step explanation:

dividing by a fraction is the same as multiplying by the reciprocal. this makes the equation 4/5 x 3/2 . multiply the numerators (4x3) and denominators (5x2). this gives 12/10. to simplify, divide the top and bottom by 2 to get 6/5

5 1/2 <br> -<br> 3 3/4<br> ______
eimsori [14]
So first you want to convert both to have the same denominator.

5 1/2 - 3 3/4

To:

5 2/4 - 3 3/4

Now, to make it easier for me, I would convert both to an improper fraction.

5 2/4 -> 22/4

3 3/4 -> 15/4

So now you can just do,

22/4 - 15/4,

which is just 7/4.

This in mixed number form is 1 3/4.

When a certain number x is multiplied by 3 and then add 4. The result is 19
rewona [7]

Hey there! I'm happy to help!

Here is our equation.

3x+4=19

We subtract 4 from both sides.

3x=15

We divide both sides by 3.

x=5.

Have a wonderful day! :D

Solve for b
Alex73 [517]

Answer:

b=\sqrt{21}

Step-by-step explanation:

Considering the given figure the sides 'b' , '2' and '5' are making the sides of a right angled triangle in the top right corner of the square, where

Hypotenuse=5  , Perpendicular=b and  Base=2

Using Pythagoras Theorem:

                (Hypotenuse)^2=(Perpendicular)^2+(Base)^2\\

       Implementing the values in the formula:

                      5^2= b^2+2^2

                     b^2=5^2-2^2\\\\b^2=25-4\\\\b^2=21\\\\b=\sqrt{21}

So, the value of 'b' is \sqrt{21} which is same for the the given 'b' in the figure.
