Answer:
He would make $36 for 12 pounds of strawberries
He would make $196 for 49 pounds of blueberries
He would make 3S if he sold S pounds of strawberries
He would make 4B if he sold B pounds of blueberries
Working:
We know that strawberries are $3/pound so $3 x 12pounds = $36
We know that blueberries are $4/pound so $4 x 49pounds = $196
The letters represent the amount of pounds of fruit being bought so the calculation for that is ($ x pounds) so you would write this but without assigning a numerical value to the amount. So if the strawberries are $3/pound and Luke sold ‘s’ pounds then it would be 3S (or 3xS but that is already assumed). The same goes for the blueberries. We know that they are $4/pound so it would be 4B.
Sorry if this doesn’t make any sense but I hope this helped

2) 
is a rhombus (a parallelogram with perpendicular diagonals is a rhombus)
3) 
bisects 
(diagonals of a rhombus bisect the angles from which they are drawn)
Answer:
0
Step-by-step explanation: Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-20y' to each side of the equation.
15x + 20y + -20y = 0 + -20y
Combine like terms: 20y + -20y = 0
15x + 0 = 0 + -20y
15x = 0 + -20y
Remove the zero:
15x = -20y
Divide each side by '15'.
x = -1.333333333y
Simplifying
x = -1.333333333y
Using a system of equations, it is found that:
- There are 8 chickens in the yard.
- There are 16 pigs in the yard.
-----------------------------------------
This question is solved using a system of equations. I am going to say that:
- x is the number of chickens.
-----------------------------------------
- A chicken has 1 head, as do a pig.
- There are 24 heads.
Thus:
-----------------------------------------
- A chicken has 2 feet.
- A pig has 4 feet.
- In total, there are 80 feet.
Thus:
-----------------------------------------
Number of chicken:
Since 
There are 8 chickens in the yard.
-----------------------------------------
Number of pigs:
There are 16 pigs in the yard.
