What is the answer to 13/4 - 5/8=

Mathematics

solmaris [256]3 years ago

In order to subtract one fraction from another, we need to make the denominator the same in both fractions.  The lowest common denominator is 8, because 4 is a factor of 8.

In order to make the denominators the same, multiply both the numerator and denominator of 13/4 by two.  This keeps the value of the fraction the same, but will equate the denominators.

\frac{13*2}{4*2} = \frac{26}{8}

At this point, we can simply subtract 5/8 from 26/8.

\frac{26}{8}- \frac{5}{8} =  \frac{21}{8}

21/8 cannot be simplified, so it is the answer.

Answer:

The perimeter of triangle is 33 meters.

Step-by-step explanation:

Given that the triangle is Equivalent Triangle where all angles and sides are equal, so we can assume that:

7x - 17 = 4x - 5

7x - 4x = 17 - 5

3x = 12

x = 12 ÷ 3

x = 4

OR:

4x - 5 = 2x + 3

4x - 2x = 3 + 5

2x = 8

x = 8 ÷ 2

x = 4

Substitute x = 4 into all expressions:

7x - 17 = 7(4) - 17 = 11 meters

4x - 5 = 4(4) - 5 = 11 meters

2x + 3 = 2(4) + 3 = 11 meters

In order to find out the perimeters, you have to add up all the sides:

P = 11 + 11 + 11

P = 33 meters

4x + 3y = 54 (1)
3x + 9y = 108 (2)

Multiply (1) by (-3)
-12x - 9y = -162 
3x + 9y = 108
---------------------add
-9x  =  -54
   x = 6

plug x = 6 into (1) to find y
4(6) + 3y = 54
24 + 3y = 54
3y = 30
  y = 10

Answer
(6 , 10)

Hope it helps.
