Given:

A rectangular piece of cloth (dimensions):

L = length of the rectangle

W = width of the rectangle

The area of the rectangle is:

A = L x W

If the cloth is cut along the diagonal, the area of one sail will be half the area of the rectangle:

A (one sail) = 1/2 (L x W) <span />

**Answer:**

<em>**The integers are 39 and 40.**</em>

**Step-by-step explanation:**

Let the smaller integer be x.

The next greater integer is x + 1.

Their sum is x + x + 1.

Their sum is 79, so

x + x + 1 = 79

Solve for x.

2x + 1 = 79

2x = 78

x = 39

x + 1 = 40

**Discussion:

$12000 * (1/5) = $2400

$12000 * ( 1/10) = $1200

As 2400 > 1200, (1/5) is the best way to go

Thank you,

MrB

1.) 6x-8y=18, 2x+8y=6 → Multiplication property of equality

2.) 8x=24 → Addition property of equality

3.) x=3 → Division property of equality

4.) 3(3)-4y=9 → Substitution property of equality

5.) 9-4y=9 → Simplify

6.) -4y=0 → Subtraction property of equality

7.) y=0 → Division property of equality

**Answer:**

False

**Step-by-step explanation:**

When multiplying two exponential numbers you add their powers together : (n3)(n7) = n10

so the expression is false
