natima [27]

Answer:

B. 2 + 6x and 2(3x + 1) Choose

D. 3x and 4(x + 1) – x – 4 Choose...

E. 5.5 + 2.1x + 3.8x – 4.1 and 1.4 + 5.9x Choose...

Step-by-step explanation:

A. 3x + 14 – x + 112 and 4x + 134 Choose...

3x + 14 - x + 112

= 2x + 126

And

4x + 134

Not equivalent

B. 2 + 6x and 2(3x + 1) Choose...

2 + 6x

And

2(3x + 1)

= 6x + 2

Yes, equivalent

C. 3(x + 1) – (1 + x) and 2x + 3 Choose...

3(x + 1) - (1 + x)

3x + 3 - 1 - x

2x + 2

And

2x + 3

No, not equivalent

D. 3x and 4(x + 1) – x – 4 Choose...

And

4(x + 1) - x - 4

= 4x + 4 - x - 4

= 3x

Yes, equivalent

E. 5.5 + 2.1x + 3.8x – 4.1 and 1.4 + 5.9x Choose...

5.5 + 2.1x + 3.8x - 4.1

For her birthday, Samantha received a gift card, with a value of $200, to a department store. She wants to purchase at least 5 a

Answer:

The correct system of inequalities is:

$\left \{ {{s + p \geq 5} \atop {24.99s + 36.99p \leq 200}} \right.$

Step-by-step explanation:

Since Samantha wants to buy at least 5 pieces of clothing, this means that the total of clothing she buys can be 5 or more, then the sum of sweaters and dress pants she have to buy is:

$s + p \geq 5$

She can't spend more than the gift card, this means that the number of clothing pieces she buys multiplied by its cost must be less or equal to the card's value, so she has to spend:

$24.99*s + 36.99*p \leq 200$
