Well 3 4/4 is equal to 4. But if you want to find the mixed number...
3 4/4 is equal to 16/4
3 4/4 is also equal to 3 2/2 or 3 8/8. The number in the end just has to equal the whole number 4.
Hope this helps!:)
It would be 29 because 8hours - 45minutes =7hours 15 minutes
7hours 15minutes divided by 15 minutes =29
X = y x z
10 = (-4) x z
Z= -10/4 = -5/2
So now we know z = -5/2
we can find y when x = 2
Again x = y x z
<span>
2 = y x
(-5/2)</span>
<span>So y =2 x (
-2/5) = - 4/5</span>
Double check:
x = yx (x = 2 , y = -4/5), z = -5/2)
<span>
2 = (-4/5) x (-5/2) = 20/10 = 2
Answer: when x = 2, y = -4/5</span>

For this case, the first thing we must do is define variables:
x: Jane's age
y: Helen's age
By writing the system of equations we have:
y = x + 8
y-20 = 3 (x-20)
Solving the system we have:
x = 24
y = 32
Answer:
Jane is 24 years old
Helen is 32 years old
the equation for Jane would look like:
x + 8 = 3 (x-20) + 20
