Answer:
z=(At-67)/(45-A)
Step-by-step explanation:
A(t+z)=45z+67
At+Az=45z+67
At=45z-Az+67
At=z(45-A)+67
z(45-A)=At-67
z=(At-67)/(45-A)
Answer:
300 feet
Step-by-step explanation:
1.) Sales Price - Original Cost / Sales Price * 100 = Percentage Markup
2.) Now substitute the values:
Sales Price - Original Cost / Sales Price * 100 = Percentage Markup
$22.95 - $17.45 / $22.95 * 100 = Percentage Markup
$5.5 / 22.95 * 100 = Percentage Markup
. .2397 * 100 = 23.97%
3.) Therefore, the store uses 23.97% as Percentage Markup
Answer:
The equation has no solution; therefore, the system of equations has no solution
Step-by-step explanation:
we have
-----> equation A
-----> equation B
we know that
If after applying the linear combination method, Heather arrived at the equation 0 = 60
then
The reason is because both lines are parallel, therefore the system of equations has no solutions
<u>Verify</u>
isolate the variable y in the equation A
--------> the slope is 1/3
isolate the variable y in the equation B
--------> the slope is 1/3
Remember that
If the slopes are equal the lines are parallel
so
The system of equations has no solutions
