Tony has $20. He wants to buy at least 4
zavuch27 [327]

Tony has $20. He wants to buy at least 4

snacks. Hot dogs (x) are $3 each.

Peanuts (y) are $2 each.​

Answer:

To solve the above question, we use the below inequality equations

x + y ≥ 4 snacks .........Inequality equation 1

3x + 2y ≤ $20 ..........Inequality equation 2

Step-by-step explanation:

We can make use of the inequality equations

Hot dogs = (x) are $3 each.

Peanuts = (y) are $2 each.​

He wants to buy at least 4

x + y ≥ 4 snacks .........Inequality equation 1

3x + 2y ≤ $20 ..........Inequality equation 2

From the above inequality equations, Tony can buy at least 4 snacks but he can only spend $20.

Let take a random number, where x = 4, and y = 4. This means Tony can buy

a) 4($3) + 4($2) = 12 + 8 = $20

The total number of snacks = 4 + 4 = 8 snacks.

b)

This answer above confirms the inequality equations 1 and 2

x + y ≥ 4 snacks .........Inequality equation 1

8 snacks ≥ 4 snacks

3x + 2y ≤ $20 ..........Inequality equation 2

$20 ≤ $20

The formula for the nth term of the arithmetic sequence first term is 9 common difference is -2
Yanka [14]

Answer:

a_n = 9 - 2(n-1)

Step-by-step explanation:

Arithmetic sequence:

In an arithmetic sequence, the difference between consecutive terms is always the same, and is called common difference.

The nth term is given by the following equation:

a_n = a_1 + (n-1)d

In which a_1 is the first term and d is the common difference.

First term is 9 common difference is -2

This means that a_1 = 9, d = -2

So, the nth term is given by:

a_n = a_1 + (n-1)d

a_n = 9 + (n-1)(-2)

a_n = 9 - 2(n-1)

The number z and -1.9 are additive inverse’s. Drag and drop -1.9 and z to their correct positions on number line . Drag and drop
juin [17]
Additive inverses add to zero. the additive inverse of any number is just that number multiplied by -1. the additive inverse -1.9 is+1.9 because when you add them the result is zero
