Answer:
x< -8.125
Step-by-step explanation:
7(x+4) < 2(x-5) -3(x+9)
distribute 7, 2, -3 to the parentheses to the right
7x+28<2x-10-3x-27
add like terms
7x+28<x-37
add x to 7x and subtract -28 to -37
8x<-65
divide both sides by 8
x<-8.125 or (-65/8)

Answer:
So, total gallons were made in all =9.31 gallons
Step-by-step explanation:
We are given
A scientist repeated an experiment three times, making 1.42, 3.81, and 4.08 gallons of a new product
so,
first experiment =1.42 gallons
Second experiment =3.81 gallons
Third experiment =4.08 gallons
now, we can find total gallons
total gallons = first experiment + second experiment + third experiment
total gallons =1.42 gallons + 3.81 gallons +4.08 gallons
total gallons =9.31 gallons
Answer: 96 adult tickets were sold that day.
Step-by-step explanation:
Let x represent the number of children tickets that were sold at the movie theatre.
Let y represent the number of adult tickets that were sold at the movie theatre.
A total of 163 tickets were sold on Tuesday. This means that
x + y = 163
child admission is $5.70 and adult admission is $9.00. The total sales made on Tuesday was $1245.90. It means that
5.7x + 9y = 1245.90 - - - - - - - - 1
Substituting x = 163 - y into equation 1, it becomes
5.7(163 - y) + 9y = 1245.90
929.1 - 5.7y + 9y = 1245.90
- 5.7y + 9y = 1245.90 - 929.1
3.3y = 316.8
y = 316.8/3.3
y = 96
x = 163 - y = 163 - 96
x = 67
