(3 1/2 - 9 3/4) divided by (-2.5)
SVEN [57.7K]

Answer:

5

Step-by-step explanation:

Let's take the numerator first

3 1/2 - 9 3/4

Convert to improper fraction

7/2 - 39/4

Find the LCM

= -25/4

Now let's take the denominator

-2.5

Convert to fraction

-5/2

Combine the two parts of the fraction

-25/4 / (-5/2)

This becomes;

-25/2 * -2/5

= +5

Nady [450]

Answer:

x = 6

Step-by-step explanation:

Givens

There are 3 sides. All are equal to (4x - 3)

Their sum = 63

Formula

3(4x - 3) = 63

Solution

  • 3(4x - 3) = 63            Divide by 3
  • 12x - 9 = 63               Add 9 to both sides
  • 12x = 63 + 9    
  • 12x = 72                    Divide by 12
  • x = 72/12

x = 6                          Answer
