Answer:

Rewrite 3 ( 4   1 /5  ) as 3 ( 4 +  1 5  ) . Distribute the 3 to get 3(4) + 3 (  1 /5  ) . Multiply to get 12 +   3 /5  . Then add to get 12  3 /5

Answer:

\frac{63}{5}

Step-by-step explanation:

 Given expression:

 

    (3) 4\frac{1}{5}  

The distributive law is mostly applied to multiplication and division which helps to expand a parentheses;

   4\frac{1}{5}   can be written as \frac{21}{5}  

 Now;

         (3) \frac{21}{5}  

 With distributive property, we simply multiply the two terms;

           3  x \frac{21}{5}     = \frac{63}{5}

Find the shortest side of a triangle whose perimeter is 64 if the ratio of two of its sides is 4:3 and the third side is 20 less
Sergio039 [100]

Answer:

The shortest side of the triangle is 18

Step-by-step explanation:

Let the sides the triangle be x, y and z.

From the question, the perimeter of the rectangle is 64, that is

x + y + z = 64 ...... (1)

Also, the ratio of two of its sides is 4:3, that is x:y = 4:3, then we can write that x/y = 4/3 ⇒ 3x = 4y ...... (2)

The third side, z, is 20 less than the sum of the other two, that is

z + 20 = x + y ...... (3)

Substitute equation (3) into (1)

Then,

z + 20 + z = 64

2z +20 = 64

2z = 64 - 20

2z = 44

z = 44/2 k

z = 22

From equation (3)

z + 20 = x + y

Then, k

22 + 20 = x +y

42 = x + y

x = 42 - y ...... (4)

Substitute this into equation 2

3x = 4y

3(42-y) = 4y

126 - 3y = 4y

4y + 3y = 126

7y = 126

y = 126/7

y = 18

Substitute this into equation (4)

x = 42 - y

x = 42 - 18

x = 24

∴ x = 24, y = 18 and z = 22

Hence, the shortest side of the triangle is 18.
