Answer:

A is correct

Step-by-step explanation:

We need to choose correct graph which has no solution.

As we know if system of equation has no solution then graph must be parallel.

For unique solution, Graph intersect at single point.

For infinite many solution, Graph coincide.

Here we need to choose graph which has no solution.

Graph must be parallel.

Option A: Both line are parallel.

This graph has no solution.

True

Option B: Intersect at one point.

Must be one solution

False

Option C: One graph coincide to another graph.

Infinite many solution.

False

Option D: Intersect at origin. It has unique solution.

False

Answer:

Equation: 8.5t+6.5=57.5

Solution: t=6

Step-by-step explanation:

Let be "t" the number of movie tickets bought by the group of friends.

According to the information given in the exercise, the price of each movie ticket is: $8.50.

Then, you can represent the amount (in dollars) the group of friends spent in movie tickets, with this expression:

8.5t

You know that one person spent $6.50, then the expression that represents the total amount (in dollars) the group of friends spent in food and movie tickets, is:

8.5t+6.5

Since that total amount spent is given in the exercise, you can write the following equation to determine how many tickets were bought:

8.5t+6.5=57.5

Finally, you can solve for "t" in order to find the solution of the equation. This is:

8.5t=57.5-6.5\\\\t=\frac{51}{8.5}\\\\t=6

4/8+1/8=5/8
the remaining distance is 8/8-5/8. so 3/8, not 1/4
