Equality Properties

Step-by-step explanation:

<u>Step 1: Define equation</u>

4x - 5 = x - 1 + 3x

<u>Step 2: Solve for </u><em><u>x</u></em>

  1. Combine like terms:                    4x - 5 = 4x - 1
  2. Subtract 4x on both sides:          -5 ≠ -1

Here we see that -5 does not equal -1.

∴ This equation has no solutions.

A rectangle school banner has a length of 44 inches, a perimeter of 156 inches , and an area of 1496 square inches. The cheerlea
kakasveta [241]
Since you have the length and the area, you can assume the width

1496/44 = Width              Because  Area = L * W

Width = 34

So this is a ratio problem

44/11 = ratio

So, the ratio is 4:1
So since we have the width, we can divide the width of the school banner by 4 because of the scale

34/4 = 8.5 = width of the sign

The area of the sign is 8.5*11 = 93.5

and the perimeter is just that,

8.5 * 2 + 11*2 = 39

Perimeter = 39 inches

Area = 93.5 inches

55÷11[120÷2{4+(10+5-7)}]​
Lynna [10]

Answer:

3600

Step-by-step explanation:

First, solve the innermost brackets first.

=> 55/11 [120 /2{4 + (10 + 5 - 7)}]

=> 55/11 [120 /2{4 + (8)}]

=> 55/11 [120 /2{4+8}]

=> 55/11 [120 /2{12}]

=> 55/11[ 60 x 12]

=> 55/11 [720]

=> 5 [720]

=> 3600
