Answer:
5 hot dogs and 9 cookies
Step-by-step explanation:
1.5(5)+0.75(9)<15
7.5+6.75=14.25
Since you do not want the variable y, you must eliminate 
Therefore, to eliminate it, you must have the opposite of it, making the answer 
The answer would be -3.333333
Step 1: (1÷3)= 0.333333
Step 2: 3+0.333333= 3.333333
Step 3: Finally you would bring the negative sign down and the answer would be -3.333333! I hope this helps :)

Answer is NOT 5a+8
5(a+3) Multiply the bracket by 5
5(a)+5(3)
5a+15
Correct answer is supposed to be: 5a+15
