You just need to plug those expressions inside the formula: it doesn't matter if they're expressions involving a variable instead of plain numbers: the formula becomes
If you want, you can simplify it by expanding the square and then multiply the two parenthesis:
<span>If tickets for the upper deck are 75% of the cost of tickets for the lower deck and lower deck tickets are $42, then tickets for the upper deck $31.50 each. Therefore the answer cannot be A or C, because both of those options misstate the cost of the upper deck ticket. The answer also cannot be D, because it expresses the inequality when the combined number of tickets is greater than $800, which is not what was asked for.
The correct answer is B. 42x + 31.5y ≤ $800. This gives the correct price for upper deck tickets and expresses the correct inequality.</span>
Answer:
x = 8/11
Step-by-step explanation:
5x - 4 = -6x + 4
Collect like terms
5x + 6x = 4 + 4
11x = 8
x = 8/11
Answer:
6x + 2y
Step-by-step explanation:
remove the bracket and collect like terms
6x + 4y - 2y = 6x + 2y
