Answer:
The answer is that x = 0 and y = -6. While this is not any of your options, the work below proves that it is correct.
In order to find these values, we can use elimination. To do so, we multiply the first equation by 5 and then add the equations together.
125x - 5y = 30
-2x + 5y = -30
------------------
123x = 0
x = 0
Now that we have this value, we can plug the value into one of the originals and find y.
25x - y = 6
25(0) - y = 6
-y = 6
y = -6
There should have been an attached image.
Area of a circle is can only be computed when the radius or diameter is provided.
Area of a circle = π r²
Based on the image I saw, the radius is 5.6 inches
A = 3.14 * (5.6in)²
A = 3.14 * 31.36 in²
A = 98.47 in² ⇒ CHOICE D. 98.5 square inches.
F= 14 and the answer is the elevator
started on the 14th floor. 14 + 7 - 9 - 4 + 8 - 2 :
14 Is that correct?
I believe that the correct measurement in feet is 1.4 x
10^5 feet. You forgot to include the ^5.
So since that is the measurement of 1 marathon, therefore
half a marathon would simply be also half of that, that is:
0.7 x 10^5 feet
or
7 x 10^4 feet
No I suck at math sorry bEsTiE
