Answer:

-60

Step-by-step explanation:

If the worker is descending, he is going down. The change in his position could be marked on a graph by translating the original point down by 60 units. Aka -60 units.

The girls tennis team was interested in raising funds for an upcoming trip. The team sold tumblers for $10 and sun hats for $5

The equations that can be used are 10T + 5S = 190 and T + S = 30.

<h3>Equations</h3>

Given that the girls tennis team was interested in raising funds for an upcoming trip, and the team sold tumblers for $10 and sun hats for $5, and when the sales were over, the team had earned $190 and sold 30 total products, which included a mix of tumblers and hats, to determine which equations can be used to represent the situation, the following calculations must be made:

T + S =190
-It cannot be used because it has any relationship with the price of the products.

10T + 5S = 30
-It cannot be used because it only considers the quantity variable.

T + S = 30
-It can be used as it shows the amount of products sold.

10T + 5S = 190
-It can be used because it relates the total price to the quantity of each product.

T + S = 15
-It cannot be used because it only considers the price variable.

5T + 10S = 190
-It cannot be used because it erroneously relates the price of each product.

Therefore, the equations that can be used are 10T + 5S = 190 and T + S = 30.

A boat has a speed of 15 mph in still water. It travels downstream from Greentown to Glenavon in g hours. It then goes back upst

Lerok [7]

Step-by-step explanation:

We want to find two things-- the speed of the boat in still water and the speed of the current. Each of these things will be represented by a different variable:

B = speed of the boat in still water

C = speed of the current

Since we have two variables, we will need to find a system of two equations to solve.

How do we find the two equations we need?

Rate problems are based on the relationship Distance = (Rate)(Time).

Fill in the chart with your data (chart attached)

The resulting speed of the boat (traveling upstream) is B-C miles per hour. On the other hand, if the boat is traveling downstream, the current will be pushing the boat faster, and the boat's speed will increase by C miles per hour. The resulting speed of the boat (traveling downstream) is B+C miles per hour. Put this info in the second column in the chart. Now plug it into a formula! Distance=(Rate)(Time) Now solve using the systems of equations!
