To find which of the given options are not the result of a substitution in the given system, we need to isolate the variable in function of the other variable, and then substitute it.
So, substituting and discarding, we have:
- First equation:
Isolating "y", we have:
Then, substituting it into the second equation, we have:
We have that it's a result of a substitutiong in the following system (option A)
- Second equation:
Isolating "y", we have:
Then, substituting it into the first equation, we have:
Have a nice day!
Hello!
There are about 0.26 gallons in a liter. Therefore we just multiply.
70(0.26)≈18.2.
I hope this helps!
To find the length of the diagonals, Troy should use the Pythagorean Theorem. The diagonal is going to be the hypotenuse of the triangle (the side directly across from the 90 degree angle).
a^2 + b^2 = c^2
6^2 + 10 ^2 = c^2
136 = c^2; find the square root of 136
c = 11.66 feet
Troy's diagonals are approximately 11.66 feet.
