3) degree: -1 / number of terms: 2

4) degree: 8 / number of terms: 2

5) degree: 2 / number of terms: 3

6) degree: 3 / number of terms: 1

**Step-by-step explanation:**

1.

The** **<u>new system</u> of **equivalent equations** are **4x + 6y = 8 and 12x + 3y = 1**

To get an **equivalent equation**, we multiply the original equation by a constant and replace it with the new equation.

So, 2x + 3y = 4 (1)

12x + 3y = 1 (2)

We multiply equation (1) by 2

So, 2x + 3y = 4 (1) × 2

⇒4x + 6y = 8 (3)

Replacing (1) by (3), we have

**4x + 6y = 8 (3) **

**12x + 3y = 1 (2) **

So, the** **<u>new system</u> of **equivalent equations** are **4x + 6y = 8 and 12x + 3y = 1.**

2.

The** **<u>new system</u> of **equivalent equations** are **3x - 21y = 24 and 5x + 4y = 20**

To get an **equivalent equation**, we multiply the original equation by a constant and replace it with the new equation.

So,

x - 7y = 8 (1)

5x + 4y = 20 (2)

We multiply equation (1) by 3, we have

So, x - 7y = 8 (1) × 3

⇒3x - 21y = 24 (3)

Replacing (1) by (3), we have

**3x - 21y = 24 (3)**

**5x + 4y = 20 (2)**

So, the** **<u>new system</u> of **equivalent equations** are **3x - 21y = 24 and 5x + 4y = 20.**

**Answer:**

390

**Step-by-step explanation:**

Only two varieties are involved: yellow and purple.

We know the ratio of yellow iris bulbs over the total is 2:5, so 40%.

That leaves 60% of the sales for the purple bulbs.

purple = (60% / 40%) * 260 = 1.5 * 260 = 390.

So, they sold 1.5 times more purple bulbs than yellow ones.

In total, the store sold 650 bulbs last year, and we hope they sell more this year.
