X + y = 3
x - y = -5

We can solve using substitution
x + y = 3
subtract x to isolate y
y = 3 - x
substitute it into the second expression
x - y = -5
x - 3 + x = -5
combine like terms
2x - 3 = -5
add 3 to both sides
2x = -2
divide both sides by 2
x = -1

now to find y

x + y = 3
-1 + y = 3
add 1 to both sides
y = 4

A taxi cab charges $1.50 for the flat fee and $0.50 for each mile. Write an inequality to determine how many miles Sharon can tr
Korvikt [17]

Answer:

C. 0.50x+1.50\leq 25

Step-by-step explanation:

Let x represent number of miles.

We have been given that a taxi cab charges $1.50 for the flat fee and $0.50 for each mile.

The cost of riding x miles would be 0.50x and the total cost of riding x miles would be 0.50x+1.50.

Since Sharon has only $25 to spend on the taxi ride, so the cost of riding x miles on taxi must be less than or equal to 25.

We can represent this information in an inequality as:

0.50x+1.50\leq 25

Therefore, option C is the correct choice.
