Answer:

A. Division property of inequality.

Step-by-step explanation:

Let be 2\cdot x > 10, we proceed to show the appropriate procedure to step 4:

1) 2\cdot x >10 Given

2) x > 5 Compatibility with multiplication/Existence of multiplicative inverse/Associative property/Modulative property/Result. (Division property of inequality)

In consequence, the division property of inequality which states that:

\forall\, a, b, c \in \mathbb{R}. If c > 0, then:

a> b\,\longrightarrow a\cdot c > b\cdot c \,\lor\, a

But if c < 0, then:

a> b\,\longrightarrow a\cdot c < b\cdot c \,\lor\, a b\cdot c

Hence, correct answer is A.

Calculate the surface area of a triangular prism. It has an isosceles triangle face with a base of 4 m and a height of 3 m. The
son4ous [18]

Answer:

48 + 18√13 cm²

Step-by-step explanation:

HC = BC/2 = 4m/2 = 2 m

AC = √AH² + HC² = √9 + 4 = √13

A = 2×A(ABC) + 2×A(ACFD) + A(BCFE)

= 2×AH×BC/2 + 2×AC×CF + BC×CF

= 2×3×4/2 + 2×√13×9 + 4×9

=12 + 18√13 + 36

= 48 + 18√13 cm²

Write two equivalent expressions to represent the area of the rectangle below.
Goshia [24]

Answer:

A=(n-3)2\ units^2

A=(2n-6)\ units^2

Step-by-step explanation:

we know that

The area of rectangle is equal to

A=LW

where

L is the length of rectangle

W is the width of rectangle

In this problem we have

L=(n-3)\ units\\W=2\ units

substitute

A=(n-3)2\ units^2

Apply distributive property

A=2(n)-2(3)

A=(2n-6)\ units^2

The cost of a whole box of chips are $60. I have $48. What percentage of the total cost do I have?
goblinko [34]

Answer:

Percentage of total I have = 80%    

Step-by-step explanation:

Given:

Price of Box = $60

I Have = $48

To Find:

Percentage I have = ?

Solution:

In this question we are just supposed to find out the percentage of the Value we have so

Percentage can be found by the formula

Percentage =\frac{Given Value}{Total}*100%

Now we have the values of all

So putting in the values

Percentage =\frac{48}{60}*100%

                    =\frac{4800}{60}%

                            = 80%

So the Percentage of total cost I have is 80%

Percentage of total = 80%
