Evan and Ian are selling wrapping paper for a fundraiser. Evan sold twice as many rolls of wrapping paper as Ian. If Evan sold 1

Answer:

Ian sold 7 rolls of wrapping paper.

Step-by-step explanation:

Let E be the number of rolls of wrapping paper sold by Evan and I be the number of rolls of wrapping papers sold by Ian.

We have been given that Evan sold twice as many rolls of wrapping paper as Ian. We can represent this information in an equation as:

$E=2I...(1)$

We are also told that Evan sold 14 rolls.

We can represent this information in an equation as:

$E=14...(2)$

To find the number of rolls of wrapping paper sold by Ian we will equate our both equation as:

$2I=14$

Let us divide both sides of our equation by 2.

$\frac{2I}{2}=\frac{14}{2}$

$I=7$

Therefore, Ian sold 7 rolls of wrapping paper.

Use the line plot to answer the questions, and describe how you figured out the answer to each question. 80 POINTS IF ANSWERD AN

antiseptic1488 [7]

X = 5 boxes

figure out the X for each person

Lizzy = 5 X

Lizzy sold: 5 * 5 = 25 boxes

Suzy = 1 X

Suzy sold: 5 * 1 = 5 boxes

John = 3 X

John sold: 5 * 3 = 15 boxes

Mark = 8 X

Mark sold: 5 * 8 = 40 boxes

Lamar = 4 X

Lamar sold: 5 * 4 = 20 boxes

→ How many boxes did Lamar sell?

Answer: 20 boxes

→ How many more boxes did John sell than Suzy?

Answer: 10 boxes

workout: 15 boxes - 5 boxes = 10 boxes more

→ How many more boxes would Lizzy have to sell to equal how many Mark sold?

Answer: 15 boxes

workout: 40 boxes - 25 boxes = 15 boxes more

Which represents the solution to 7x > 21 or 6x - 9 < 21?

olganol [36]

Answer:

1) The correct option is the third line

2) The correct option is the third line please see attached graph

Step-by-step explanation:

For the system of inequalities,

7·x > 21 or 6·x -9 < 21 we have;

7·x > 21

x > 21/3 = 3

x > 3

Also we have for 6·x -9 < 21 we have;

6·x -9 < 21

6·x < 21 + 9

6·x < 30

x < 30/6 = 5

x < 5

The representation of the region x > 3 and the region x < 5 on the number line consists of indicating points 3 and 5 with circles not filled to represent less than < and not less than or equal to ≤ and shading the potion of the number line in between the two points

Which gives the correct option as the third line which has an open circle at point 3 and 5

b) To graph the inequality v + 4 > 2 and 8·v - 20 ≤ 36

For the inequality v + 4 > 2, we have;

v > 2 - 4

v > - 2

For the inequality 8·v - 20 ≤ 36, we have;

8·v - 20 ≤ 36

8·v ≤ 36 + 20

8·v ≤ 56

v ≤ 56/8

v ≤ 7

The region representing v > -2 or v ≤ 7 on the number line consists of indicating points -2 with a circle (not filled) to represent less than < and point 7 with a filled circle to represent less than or equal to ≤ and shading the potion of the number line in between the two points

Which gives the correct option is the third line which has a closed circle at point -2 and an open circle at point 7
