Answer:
x = 4y+28
Step-by-step explanation:
x/4 -7 = y
Solve for x
Add 7 to each side
x/4 -7+7 = y+7
x/4 = (y+7)
Multiply each side by 4
x/4*4 = 4(y+7)
x = 4y+28

a squared + b squared = c squared for the sides and hypotenuse of the triangle.
6^2 + 6^2 = c^2
36 + 36 = c^2
72 = c^2
c = square root of 72, 8.49
The answer is (6/25). I just multiplied the 2 numbers, but I'll explain with something simpler:
Take the number 100, let's say I want (1/10) from that 100,
and from that (1/10), I want (4/5).
Well a tenth of 100 is 10, and four fifths of 10 is 8, thus we have 8/100 as a total (or 4/50)
The same answer can be found when multiplying (1/10) and (4/5), giving us (4/50) or (8/100)
