Answer: a = 0.3
Step-by-step explanation:
First, distribute(-1)
5.3a-0.8-1.6+4.7a=2a-(a-0.3)
Then, distribute(-1)
5.3a-0.8-1.6+4.7a=2a-a+0.3
Then, combine like terms
10a-2.4=a+0.3
Then, add(2.4)
10a=a+2.7
Then, subtract(a)
9a=2.7
Then, divide(9)
a = 0.3

Answer:
9 dollars
Step-by-step explanation:
Solve with a system of equations
Let adult tickets be a and student tickets be s
1. 8a + 13s = 176
2. 4a + 4s = 68
3. s = 17 - a
Equation 2 is friendlier, so let's divide all the numbers by 4.
a + s = 17
Equation is s = 17 - a
Substitute s in equation 1
8a + 13(17-a) = 176
8a + 221 - 13a = 176
221 - 5a = 176
5a = 45
a = 9
The price of an adult ticket is 9 dollars

Answer:
x - 4 > 2x
(see below to solve for x if needed)
Step-by-step explanation:
"Greater than" is key word for the greater than symbol: >.
"A number" can be represented by x.
So "a number minus four" would be x - 4 and "two times a number" would be 2x.
So "A number minus 4 is greater than 2 times a number" is:
x - 4 > 2x
If you were to solve for x, it would be:
x - 4 > 2x
-x -x
-------------
-4 > x
x < -4
