Remark
The equation is job1/ time + job2/time = job3/time
Discussion
job one is the time it takes one of the workers to complete the job.
job two is the time it takes the other workers to complete the job
job three is the time it takes to do the job together.
Givens.
Let Marcus's time = m
Let Tony's time be =t
Let their together time = t1
Equation Substitution and solution.
1/m + 1/t = 1/t1
1/6 + 1/4 = 1/t1 The common denominator on the left is 12.
2/12 + 3/12 = 1 / t1
5/12 = 1/t1 Cross multiply.
5*t1 = 12 Divide by 5
t1 = 12/5
t1 = 2 2/5
t1 = 2.4 hours
Cost
1 hour = 43 dollars for labor.
2.4 hours = x dollars for labor.
1*x = 43 * 2.4
x = 103.2 dollars. <<<<< Answer
Answer:
Step-by-step explanation:
Solving For V.
2v=−10x
You need to divided both sides by 2.
2v
/2 = −10x
/2
v = −5x
Answer:
v = −5x
Answer:
The answer to your question is the first graph in the second line.
Step-by-step explanation:
First graph in the first line: it shows a positive graph that intercepts the y-axis in 5, then this graph is not the correct answer.
Second graph in the first line: it shows a negative graph, this option is incorrect, we look for a positive graph.
First graph in the second line: is correct because is a positive graph and intercpts the y-axis in 4.
Second graph in the second line: is incorrect although it is a positive graph, it intercepts the y-axis in 3.
