Answer:
10 nickels and 10 quarters
Step-by-step explanation:
Given
Number of coins: 20
Vaiue of coins = $3.00
Required
Number of Nickels and Quarters;
<em>Let N =Nickels and Q =Quarters</em>
The total coins is represented as:

1 nickel is equivalent to $0.05 and 1 quarter is equivalent to $0.25; So

Make N the subject of formula in the first equation

Substitute this in the second equation


Collect like terms


Multiply both sides by 5


Recall that N = 20 - Q


Answer:
False
Step-by-step explanation:
Vertical angles are a pair of opposite angles created by intersecting lines. The Vertical Angles Theorem states that if two angles are vertical, then they are congruent.
There are 5820 ft per mile
so the answer is 5820ft/min

For this case we have that by definition, the point-slope equation of a line is given by:

Where:
m: It's the slope
b: It is the cut-off point with the y axis
We have two points:

We found the slope:

Thus, the equation is of the form:

We substitute one of the points and find "b":

Finally, the equation is:

Answer:

100 = number of sets of clubs manufactured per month
S = sell-price for a set of clubs
Expenses per month = 23,250 + 145(100) = 37,750
Revenue per month = 100 S
Break-even when Expenses = Revenue
<u>100 S = 37,750</u>
One question: How did you solve it without an equation ?
