Hello! 3x + 20 and 8x - 5 are equal. To find the value of "x", we should set up and solve an equation. It would be written like this:
3x + 20 = 8x - 5
First off, subtract 3x from both sides in order to get 20 = 5x - 5. Add 5 to both sides to get 25 = 5x. Now, divide each side by 5 to isolate the "x". 25/5 is 5. Now, let's plug in the value and see if it works. 3 * 5 is 15. 15 + 20 is 35. 8 * 5 is 40. 40 - 5 is 35. 35 = 35. There. x = 5.

Answer:
The pears are more expensive per pound
Step-by-step explanation:
Find the cost per pound of the pears and bananas by dividing the cost by the number of pounds:
Pears:
9/3
= 3 ($3 per pound of pears)
Bananas:
1/4
= 0.25 ($0.25 per pound of bananas)
Since 3 is larger than 0.25, this means the pears are more expensive per pound.
