Hope this helped. (got taken off because I did the steps? oo well)</span>
Answer:
I'm sorry I dint understand the question very well
-3(x + 5) = -9
-3x + -15 = -9
-3x - 15 = -9
-3x - 15 + 15 = -9 + 15 (we added 15 to both sides of the equation because now, the 15 on the left side cancels out).
-3x = 6
-3x/-3 = 6/-3
X = -2
So, in conclusion, X is equal to -2.
The question is incomplete. The complete question is as follows.
Juan, Carlos and Maria went to the museum. The entrance ticket cost $5 per person, but, as they are students, there is a discount of $1 per ticket. After, they bought: 3 combos of chicken and fries costing $4 each; 3 bottles of water costing $1 each; 3 vanilla cookies costing $1 each; How much money each student paid if they divided the costs in equal amount?
Answer: $10
Step-by-step explanation: As each students split the bill in equal parts, to find how much they spent, we can calculate how much one of the three spent.
For ticket: 5 - 1 (because of the students discount) = $4
Each combo of chicken and fries cost $4, so: combo = $4
Each bottle of water costs $1, so: water = $1
and each vanilla cookie costs $1: cookie = $1
Total spent is:
T = 4+4+1+1
T = 10
Each student spent a total of $10 for this outing.
Answer/Explanation:
3) 10x + 5y means the price of an adult ticket and any number of people who would purchase one and the price of a child ticket and any number of people who would purchase one
4) the variable “x” is any number of people purchasing an adult ticket and the variable “y” is any number of people purchasing a child ticket
5) since we already know what the variable “y” is from the question above, the parenthesis (5 + 1 + 1.50 + 3) represents the data from the chart: the cost of a child admission ticket, child ride ticket, a pizza slice, and one cotton candy
6) the expression x + y expresses the total number of adults and child who would attend the local fair
