1. Equivalent Expressions are written quantities that are equal.

To find equivalent expressions, it looks like you can just expand the second expression and then see if it matches the first.

2. So, expand 5(2x+3) using the distributive property.

5(2x+3) = 5×2x + 5×3 = 10x+15

It matches the first expression which means that they are equivalent.

I will also do 2-5 for you to check your work.

3. -2(-6+5) = 12-10 = 2            2 ≠ 12x-10

not equivalent

4. 3(4x+5) = 12x+15              12x+15 ≠ 12x-15  

not equivalent

5. -(-4x-3) = 4x+3                    4x+3 ≠ 4x-3

not equivalent

Sarah Meeham blends coffee for Tasti-Delight. She needs to prepare 120 pounds of blended coffee beans selling for $5.17 per poun
guajiro [1.7K]

Answer:

a) 80 ibs

b) 40 ibs

Step-by-step explanation:

Let X be the pound of the high quality bean at $6.50

(120-x) will be the pound of the cheaper bean at $2.50

6.5x + 2.5(120 - x) = 5.17(120)

6.5x + 300 - 2.5x = 620.4

Collect like terms

6.5x - 2.5x = 620.4 - 300

4x = 320.4

x = 320.4/4

x= 80.1

x = 80 ibs(to the nearest pounds)

For the cheaper bean we have 120 -x

= 120 - 80

= 40 ibs

Sarah would blend 80 ibs of quality bean and 40 ibs of cheaper bean
