The ladder is the hypotenuse of a 45 45 90 triangle.
The legs of a 45 45 90 triangle = hypotenuse / sqroot (2)
15 / 1.414 = 10.608
(Incidentally it is the "bottom" of the ladder that is 10.608 feet from the wall. The "top" of the ladder is touching the wall. LOL)
multiply the whole number with the denominator then add the numerator over the denominator then find the common multiple.
Alrighty, first off you would move the 2y to the left side and change its sign and move the constant (2) to the other side and change its sign.
3y - 2y = 5x - 2
Next you would collect the like terms for y.
y = 5x - 2
And because you cannot do anything else with the problem that is the final answer: y = 5x - 2
Hope this helps! :)
A, the student failed to distribute. In his step one, he got 3x + 2 =y, but it's actually 3x + 6 = y
I got this by distributing 3 to both x and 2, which is 3x and 6.
The answer is 3 because 3 feet below sea level is -3 and the integer for -3 is 3
