Answer:

An answer that is approximately exact is an Estimation

Step-by-step explanation:

If we find the result of an operation approximately we are estimating.

The estimation can be very useful if we do not need an exact answer but an closely answer.

For example when we round the quantities first, then we perform the operation, that is an estimation. Also when we use significant figures

If x€{-2,-1,0,1,2,3,4,5} find the solution set 7-x>0 ii 3-4x>-2 vi 3x+4>-2

maw [93]

Answer:

i) {-2 , -1 , 0 , 1 ,2 , 3 , 4 , 5}

ii) {-2 , -1 , 0 , 1}

iii) {-1 , 0 , 1 ,2 , 3 , 4 , 5}

Step-by-step explanation:

i) 7 - x > 0

⇔ 7 > x

⇔ x < 7

⇔ x ∈ {-2 , -1 , 0 , 1 ,2 , 3 , 4 , 5}

____________________________

ii) 3 - 4x > -2

⇔ 3 + 2 > 4x

⇔ x < 5/4

⇔ x ∈ {-2 , -1 , 0 , 1}

____________________________

iii) 3x + 4 > -2

⇔ 3x > -2 - 4

⇔ 3x > -6

⇔ x > -6/3

⇔ x > -2

⇔ x ∈ {-1 , 0 , 1 ,2 , 3 , 4 , 5}

A rectangular room has an area of 131 1/4 square feet. The length of the room is 12 1/2 feet. What is the width, in feet, if the

icang [17]

<h2>Greetings!</h2><h3>Answer: 10 1/2 feet</h3><h3>Explanation:</h3>

As the room is a rectangle, to find the area you simply multiply the length and width together.

L x W = A

As in the question stated you have the area and length:

12.5 x W = 131

To find the width you can simply divide the area by the length:

131 ÷ 12.5 = 10.48 ≅ 10.5 = 10 $\frac{1}{2}$

<h3>So the width is 10 $\frac{1}{2}$ feet</h3>

What expression is equivalent to 4(n- 3^2) + n?<br> Thats 3 squared with 2

Lelechka [254]

Given that,

An expression : 4(n- 3²) + n

To find,

The equivalent expression.

Solution,

We have,

4(n- 3²) + n

As 3²= 9

= 4(n- 9) + n

Opening the brackets,

= 4n-4(9) + n

= 4n-36 +n

= 5n-36

Hence, the equivalent expression is 5n-36.
