Answer:

(i) a∗b=a−b

Check commutative is

a∗b=b∗a

a∗b=a−b

b∗a=b−a

Since, a∗b



=b∗a

∗ is not commutative.

Check associative

∗ is associative if

(a∗b)∗c=a∗(b∗c)

(a∗b)∗c=(a−b)

∗

c=(a−b)−c=a−b−c

a∗(b∗c)=a∗(b−c)=a−(b−c)=a−b+c

Since (a∗b)∗c



=a∗(b∗c)

Solve for A if F=MA and F=10 and M=2.5

gogolik [260]

Answer:

$\boxed{\sf A = 4}$

Given:

F = MA

F = 10

M = 2.5

To Find:

Value of A

Step-by-step explanation:

$\sf Substituting \ values \ of \ F \ and \ M \ in \ F = MA:$

$\sf \implies 10 = 2.5A$

$\sf \implies 2.5A = 10$

$\sf Dividing \ both \ side \ of \ 2.5A = 10 \ by \ 2.5:$

$\sf \implies \frac{2.5}{2.5} A = \frac{10}{2.5}$

$\sf \frac{2.5}{2.5} = 1 :$

$\sf \implies A = \frac{10}{2.5}$

$\sf \frac{4 \times \cancel{2.5}}{ \cancel{2.5}} = 4 :$

$\sf \implies A = 4$

Kyle is making a frame for a rectangular piece of art. The length of the frame is 3 times the width, as shown below.

NeX [460]

Answer:

3.75 feet

Step-by-step explanation:

The length of the frame is 3 times the width.

Let the width be x.

The length will be 3x.

Kyle uses 10 feet of wood to make the frame. This means that the perimeter is 10 feet.

The perimeter of a rectangle is:

P = 2(L + W)

=> 10 = 2(3x + x)

=> 10/2 = 4x

5 = 4x

=> x = 5/4 = 1.25 feet

The width is 1.25 feet. The length is therefore:

1.25 * 3 = 3.75 feet
