Answer:
Step-by-step explanation:
5x−3y>−15
Step 1: Add 3y to both sides.
5x−3y+3y>−15+3y
5x>3y−15
Step 2: Divide both sides by 5.
5x/5 > 3y - 15/5
x > 3/5y - 3
Answer:
-1/7 y + 1/7 x
Step-by-step explanation:
Can also be written as
1/7 x - 1/7 y
A graphing calculator shows the x-intercepts of the expression on the left to be -1, 4, 7.
The real solutions to the cubic equation are x ∈ {-1, 4, 7}.
Variable is "a" and the expression is 6-a
Answer:
The ticket is bought for 28 students.
Step-by-step explanation:
It is given that the teacher is going to buy museum ticket for each students.
Total money spent = $182
Price of each ticket = $6.50
Let total number of tickets bought =
We know that to find the total amount of money spent on ticket, we can add price of each ticket (i.e. $6.50) number of times.
OR
In other words, simply multiply the number of tickets with price of each ticket to find the total money spent.
Total money spent =
We know that total money spent is $182.
The ticket is bought for 28 students
