Answer:

$60

Step-by-step explanation:

Profit = revenue - total cost

cost is total expenses incurred in running the business

total cost = cost of rent and the expensive saws and equipment + cost of wood + amount paid to worker

50 + 30 + 10 = 90

revenue is the amount earned from selling the chairs. it is equal to 150

Profit = 150 - 90 = 60

how do you solve a system of equations approximately given tables without using equations or graphing?

solong [7]

system of equations means that we have a given number of equations with the same solutions.

If you only have tables, this means that you need to have one table for each equation:

For example, if you are working only with two variables, x and y, in those tables you can see the pints (x, y) that belong to each equation.

Now, a point (x, y) will be a solution of the system of equations only if it belongs to the data table for each equation

This would mean that if you graph those data sets, the graphs will intersect at the point (x, y) that belongs to all the tables of data.

another way may be using the data in the tables to construct the equations, but you said that you only want to use the tables, so this method can be discarded.

Based on the work shown on the right, check all of the possible solutions of the equation.

Mazyrski [523]

Incomplete question. However, here is a similar question attached.

Solve 3x^2 + 17x - 6 = 0.

Based on the work shown to the left, which of these values are possible solutions of the equation? Check all of the boxes that apply

A X=-6

B X=6

C X=-1/3

D X=1/3

E X=0

Answer:

A and D

Step-by-step explanation:

Note that such question requires using completing the square method of solving equations. By using the values X= -6 and X= 1/3 we arrive at a solution.
