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

Answer:
The width of the rectangle is <u>7 feet</u>.
Step-by-step explanation:
Given:
The perimeter of a rectangle is 54 feet, and the length is 13 feet more than the width.
Now, to find the width of the rectangle.
Let the width be
So, the length is
Perimeter = 54 feet.
Now, to get the width we put formula:
<em>Subtracting both sides by 26 we get:</em>
<em>Dividing both sides by 4 we get:</em>
Therefore, the width of the rectangle is 7 feet.
Answer:
a) 86,314.
b) 9,162,500.
Step-by-step explanation:
(a) 838(100 + 3)
= 83800 + 2514
= 86314.
(b) 91625 x 179 - 91625 x 79
= 91625(179 - 79)
= 91625 x 100
= 9162500.
