Whenever you add or subtract fractions, the denominators must be the same.

in the first problem, the denominators are the same so we just add the top numbers. so 4/7 + 1/7 = 5/7.

in the second, they again all have 9 on the bottom so we can add the top. so 2/9 + 3/9 + 1/9 = 6/9. However 6/9 can be reduced. 6 and 9 are both divisible by 3. so after we divide them we get 2/3 for our answer.

finally, the denominators are the same so we can just subtract the top. 7/8 - 2/8 = 5/8.

Ishaan and his friends have 40$ to spend at a restaurant.
Paul [167]

The number of salads Ishaan and his friends can afford is 6 salads.

<h3>What are Word Problems?</h3>

Word Problems in mathematics involve crucial understanding and the use of variables and arithmetic operations to solve real-life cases.

From the given information;

  • The total amount with Ishaan and his friends = $40
  • If they decided to spend the money on salad(x) and one salad(x) cost = $6

Thus, the number of salads they can purchase is:

\mathbf{x = \dfrac{\$40}{\$6}}

x = 6 salads remaining $4

Therefore, we can conclude that the number of salads they can purchase with $40 is 6 salads with a remaining amount of $4.

The vertex is (105,7)

Notice how on the graph, the y value peaks at 7. The y values to the left and right are symmetrical, meaning that the x value for the y value of 7 is the axis of symmetry, and the point (105,7) is the vertex.
