-3 + 3n = -6 - 6n. Expand the brackets
3n + 6n = -6 + 3. Collect like terms
9n = -3
n = -3/9 = -1/3
The symbol "<=" without quotes means "less than or equal to"
-6x + 2y <= 42
-6x + 2y + 6x <= 42 + 6x ... Add 6x to both sides
2y <= 6x + 42
2y/2 <= 6x/2 + 42/2 ... divide every term by 2
y <= 3x + 21
So the answer is choice D
Answer: Ric will get $4.50 back in change
Step-by-step explanation: $1.25 each cover times 4 covers is $5. 2/5 of 1.25 is .50. add $5 and $.50 is $5.50. if he pays with a ten, subtract, and he will get $4.50. hope this helpedd❤️
