Answer:
65.75% change
Step-by-step explanation:
Equation for percent change
(|x2-x1| / x1) * 100%
48 million / 73 million * 100% = 65.75% decrease
Answer:
Anything. Variables look like anything, because a variable is just a placeholder for whenever you want to put in another number.
Some examples: x, y, Ф, β
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
