Let C represent the cost in dollars and R represent the revenue in dollars. What is the break-even point? Use a table to help if
BigorU [14]

Answer:

x = 5

R = C = 225

Step-by-step explanation:

Given

C = 15x + 150

R = 45x

Required

The break even point

To do this, we make use of:

R =C

45x=15x + 150

Collect Like Terms

45x-15x = 150

30x = 150

x = 5

Substitute 5 for x in R = 45x

R = 45 * 5

R = 225

Hence, the break even point is:

x = 5

R = C = 225

Write a number with one decimal place,that is bigger than 6 4/5 but smaller than 7 how can I solve this
statuscvo [17]
Hello!

The easiest way to solve this would be to convert 6 4/5 to a decimal. We know that to convert a fraction to a decimal, we must divide the numerator by the denominator. 

4 / 5 = 0.8 

0.8 + 6 = 6.8

So, 6 4/5 is 6.8 as a decimal. 

See how it's easier now that we've converted the mixed number to a decimal? 

There could be many numbers between 6.8 and 7. Some examples are: 

6.81, 6.82, 6.83, 6.9, etc.

Solve the following using the elimination or substitution method. Show all work.
ki77a [65]

Jim has 28 nickels and 37 dimes in his pocket. which is determined by the substitution method.

<h3>What is the equation?</h3>

The term "equation" refers to mathematical statements that have at least two terms with variables or integers that are equal.

Let the number of nickels would be n

Let the number of dimes would be d

As per the given question,

d + n = 65  ....(i)

0.10d + 0.05n = 5.10  ....(ii)

From equation (i),

d + n = 65

d + n - n = 65 - n

d = 65 - n

Substitute in for the equation(ii): d = 65 - n

0.10(65 - n) + 0.05n = 5.10

6.5 - 0.10n + 0.05n = 5.10

6.5 - 0.05n = 5.10

6.5 - 0.05n - 6.5 = 5.10 - 6.5

- 0.05n = -1.4

n = 28

This means there are 28 nickels

Substitute the value of n = 28 in the equation (i),

d + n = 65

d + 28 = 65

d = 37

So there are 37 dimes

Thus, Jim has 28 nickels and 37 dimes in his pocket.
