Using the properties of inequalities, write down the inequality that you will get if you: add the number –5; 2.7; 7; to both sid

puteri [66]

Answer:

See below

Step-by-step explanation:

1..........................

18 >−7

Add –5; 2.7; 7 to both sides

18 -5 > -7 - 5 ⇒ 13 > -12
18 + 2.7 > - 7 + 2.7 ⇒ 20.7 > - 43
18 + 7 > -7 + 7 ⇒ 25 > 0

2..........................

5 > -3

Subtract 2; 12; -5 from both sides

5 - 2 > -3 -2 ⇒ 3 > - 5
5 - 12 > -3 - 12 ⇒ -7 > -15
5 -(-5) > -3 - (-5) ⇒ 10 > 2

3..........................

- 9 < -6

Multiply both sides by 3; −3; −1

<em>When multiplying both sides of inequality by positive number the sign stays as is, when multiplying both sides of inequality by negative number the sign reverses</em>

-9 *3 < -6*3 ⇒ -27 < - 18
-9*(-3) > -6*(-3) ⇒ 27 > 18
-9*(-1) > -6*(-1) ⇒ 9 > 6

A carpenter is assigned the job of expanding a rectangular deck where the width is one-fourth the length. the length of the deck

anzhelika [568]

Alright, lets get started.

Suppose the original deck size: width = x feet

the width is one-fourth the length given in question means length = 4 x feet

Means the originally area = $x * 4 x = 4 x^{2}$

Now the dimensions are changed.

New dimensions, width = (x + 6)

new length = (4x+10)

So, new area will be = $(x+6) * (4x+10) = 4x^{2} + 10 x + 24 x + 60 = 4x^{2} + 34 x + 60$

the area of the new rectangular deck is 128 ft2 larger than the area of the original deck, means

$4x^{2} + 128= 4x^{2} + 34 x + 60$

Subtracting $4x^{2}$ from both sides

$128 = 34 x + 60$

Subtracting 60 from both sides

$128 - 60 = 34 x + 60 - 60$

$68 = 34 x$

Dividing 34 in both sides

$\frac{68}{34} = \frac{34 x }{34}$

$x = 2$

Means width = 2 feet

Length would be = 4 time width = 4 * 2 = 8 feet

Means dimension of original deck would be = 2 feet and 8 feet :Answer

Hope it will help :)
