39=1 3/10b solve the equation

Answers

Answer 1
Answer:
                                            39  =  (1 and 3/10) b

Let's change that ugly mixed number to a fraction
so that we can work with it.

                   (1 and 3/10)  =  (10/10 and 3/10)  =  13/10

Now the equation says     39  = 13/10  b  

We could multiple
each side by 10:              390  =  13 b

Divide each side by 13:    390 / 13  =  30  =  b

Whenever you're trying to solve any equation, the whole idea is: 

-- Do whatever you need to do in order to get the variable all alone
on one side of the equation and everything else on the other side. 

-- You can do anything you want to do on either side of the equation,

BUT ...

-- whatever you do to one side, you must IMMEDIATELY do the same thing
to the other side.

Which one is bigger 2/3 or 4/7

Answers

Answer:

(2)/(3)

Step-by-step explanation:

To compare the fractions we require them to have a common denominator.

The lowest common multiple of 3 and 7 is 21

Change both fractions into fractions with a denominator of 21

(2(7))/(3(7)) and (4(3))/(7(3))

= (14)/(21) and (12)/(21)

The numerator 14 is greater than 12, hence

(2)/(3) is the larger fraction

Answer:

2/3

Step-by-step explanation:

To find whether a fraction is bigger than the other, we need to make the denominators the same.

First we see what number we can change 3 and 7 into, so it can be made the same.

I chose the number 21 as 21 is in the 3 times tables and the 7 times tables.

Then because I multiplied 3 by 7 to make 21 , I multiply the numerator which is 2 by 7 as well which is 14.

This makes 14/21.

We need to multiply the numerator of the other fraction to because we multiplied the denominator by 3 so we do 4 multiplied by 3, to make 12.

This makes 12/21.

We can see here that 14/21 is greater than 12/21, therefore 2/3 is greater than 4/7.

The perimeter ofthe rectangular playground shown
below is 160 feet. What is the area of the
playground?

Answers

2,500 feet is the answer to your question. hope this helped

Known :

Perimeter = 160 ft

length = 50 ft

Asked :

Area = ...?

Answer :

Find the width first :

Perimeter = 2 (length + width)

160 = 2 (50 + width)

width = (160 ÷ 2) - 50

width = 80 - 50

width = 30ft

Now, let's find the Area :

Area = length × width

= 50 × 30

= 1.500ft²

So, the area of the playground is 1.500ft²
