Standard CDs have a diameter of 120 millimetres (4.7 in) and can hold up to about 80 minutes of uncompressed audio or about 700 MiB of data.
Answer:
690
Step-by-step explanation:
Let
hayden have "h"
uri have "u"
and
willow have "w"
Hayden & Uri have 1250. we can write:
h + u = 1250
Hayden & Willow have 830, so we can write:
h + w = 830
Uri has 4 times than Willow, so we can write:
u = 4w
Putting 3rd equation in first, we get:
h + u = 1250
h + 4w = 1250
Now, we take 2nd and 4th equation, which are:
h + w = 830
h + 4w = 1250
Multiplying this first one with -1, gives us:
-1 * [h+w=830] = -h - w = -830
Now we add this up with 4th equation. Shown below:
- h - w = - 830
h + 4w = 1250
----------------------
4w - w = 1250 - 830
3w = 420
w = 420/3
w = 140
We know u = 4w, so u = 4 * 140 = 560
u = 560
Also, we know h + w = 830, so
h + 140 = 830
h = 830 - 140
h = 690
Thus Hayden has 690
Answer:
x in (-oo:+oo)
y = (-2/3)*x+1 // - (-2/3)*x+1
y-((-2/3)*x)-1 = 0
(2/3)*x+y-1 = 0
2/3*x+y-1 = 0 // - y-1
2/3*x = -(y-1) // : 2/3
x = (-(y-1))/2/3
x = 3/2*(1-y)
x = 3/2*(1-y)
(hope that helps you out :)
