(5m-4)/6 -1 = 4m - (3m+10)/2 pls answer fast

Debora [2.8K]

Answer:

Step-by-step explanation:

$\frac{(5m - 4)}{6} - 1 = 4m - \frac{(3m + 10)}{2}$

$= > \frac{5m - 4 - 6}{6} = \frac{8m - 3m - 10}{2}$

$= > \frac{5m - 10}{6} = \frac{5m - 10}{2}$

[Cross Multiplication]

=> 2(5m - 10) = 6(5m - 10)

=> 10m - 20 = 30m - 60

=> 60 - 20 = 30m - 10m

=> 40 = 20m

$= > m = \frac{40}{20}$

=> m = 2 (Ans)

Does anyone know what 7600 53/8 simplified is

Yuliya22 [10]

Answer:

53/8 = 53/8

Step-by-step explanation:

Here we will simplify 53/8 to its simplest form and convert it to a mixed number if necessary.

In the fraction 53/8, 53 is the numerator and 8 is the denominator.

When you ask "What is 53/8 simplified?", we assume you want to know how to simplify the numerator and denominator to their smallest values, while still keeping the same value of the fraction.

We do this by first finding the greatest common factor of 53 and 8, which is 1.

Then, we divide both 53 and 8 by the greatest common factor to get the following simplified fraction:

58/3

Therefore, this equation is true:

53/8 = 53/8

If the numerator is greater than or equal to the denominator of a fraction, then it is called an improper fraction. In that case, you could convert it into a whole number or mixed number fraction.

53/8 = 6 5/8

-Hope this helps.

Find and simplify an expression for the area of two rows of b squares with side lengths of b centimeters. Please help!

Ronch [10]

Answer:

The complete area of the given figure is $(2 b^3) cm^2$

Step-by-step explanation:

Total number of rows = 2

Squares in each row = b

So, the total number of squares in 2 rows = 2 x ( Squares in 1 row ) = 2 x b

Also, side length of 1 square = b cm

As we know, AREA OF SQUARE = SIDE x SIDE

So here, area of 1 square = Side x side = b cm x b cm = $(b^2) cm^2$

⇒ The area of total (2b) squares = 2 b x ( Area of 1 square)

$= 2 b \times (b^2) = 2 b^3$

Hence, the complete area of the given figure is $(2 b^3) cm^2$
