Answer:
We need to right the proper algebraic expression to each case.
(a) Number x greater than y
![x>y](https://img.qammunity.org/2021/formulas/mathematics/high-school/dpde7zs6g2ghkmx0f3wz3zvxa16cwpxnro.png)
(b) The product of 2a and b is
![2a * b = 2ab](https://img.qammunity.org/2021/formulas/mathematics/college/h79j9pfmtqu8h58mvhw1ugbmp37pvzwyf3.png)
(c) You want to by x chocolates for $2 and y chocolates for $3, how much would you pay for the purchase?
![Total =2x+3y](https://img.qammunity.org/2021/formulas/mathematics/college/dzqb38x7f7ru23w2ksqh1iosqsmoc7fpzm.png)
(d) Mr. Jan has x chickens and y cows, how many legs there are in total?
Each chicken has two legs, and each cow has four legs, so the expression of the total number of legs is
![L=2x+4y](https://img.qammunity.org/2021/formulas/mathematics/college/vym06cuddezhzqx7ttdl00b6sztwxbdc9a.png)
Where
represents chickens and
represents cows.
