Answer:

5x + 2x < 120

Step-by-step explanation:

Given:

Binh takes 5 minutes to repot each plant and 2 minutes to water each plant.

He has at most 2 hours.

Here "at most" represents by the inequality "<"

Let's convert 2 hours into minutes.

1 hour = 60 minutes

2 hours = 2×60 minutes = 120 minutes

Let x represent the number of plants to repot, and y represent the number of plants to water.

So, the given situation represented by

5x + 2x < 120

Mr. Turney wrote the value statement "x = 2" on the whiteboard. He asked his students to create an equation or inequality with t
boyakko [2]

Answer:

Some of the equations can be written as-

1. 2x = 4

2. 3x + 9 = 15

3. x + 5 = 7

4. 5x - 2 = 8

Step-by-step explanation:

Given - Mr. Turney wrote the value statement "x = 2" on the whiteboard.

To find - He asked his students to create an equation or inequality with

              this value as a solution.

Proof -

Given that, The value statement is ''x = 2''

We have to find out that equation in such a way that if we solve the equation , we get the value x = 2

There can be infinite many equation that give the value statement '' x = 2''

Some of the equations can be written as-

1. 2x = 4

2. 3x + 9 = 15

3. x + 5 = 7

4. 5x - 2 = 8

And many more.

Verification -

1. 2x = 4

⇒x = \frac{4}{2}

⇒x = 2

Verified

2. 3x + 9 = 15

⇒3x = 15 - 9

⇒3x = 6

⇒x = \frac{6}{3}

⇒x = 2

Verified

3. x + 5 = 7

⇒x = 7 - 5

⇒x = 2

Verified

4. 5x - 2 = 8

⇒5x = 8 + 2

⇒5x = 10

⇒x = \frac{10}{5}

⇒x = 2

Verified

balu736 [363]

Atticus will spend $1.60 on wrapping paper.

Step-by-step explanation:

Given,

Cost of paper per yard = $2.40

Atticus wants to buy = 2/3

Cost of 2/3 yards of paper = \frac{2}{3}*2.40

Cost of 2/3 yards of paper = \frac{4.80}{3}

Cost of 2/3 yards of paper = $1.60

Atticus will spend $1.60 on wrapping paper.
