use the Per-Pupil Expenditure column to compare how much each state spends on average for each student. Total expenditure for the state can be misleading. A state with a high number of students could have a high overall expenditure, even if it doesn't spend very much on each student. I'm more concerned about how much the state is likely to spend on each of my children, not how much they spend overall.
Step-by-step explanation:
The simplest form of 85 over 100 is 17 over 50
When x is doubled, y is doubled. When z is multiplied by 5/8, so is y. The result of both changes is that y is multplied by 2·(5/8) = 5/4. The new value of y is
... y = 5/4·320 = 400
_____
If you really want to, you can use the formula
... y = kxz
and compute the value of k as
... k = y/(xz) = 320/(4·16) = 5
Then use this formula with the new values of x and z:
... y = 5·8·10 = 400
D because 6.2=100
6.2×1.4=8.68
so 100×1.4=140
140-100=40
so it's 40%
G(x) = 3x - 5
let g(x) = y
y = 3x - 5
y + 5 = 3x
3x = y + 5
x = (y + 5)/3
From y = g(x), x = g⁻¹(y)
<span>x = (y + 5)/3
</span>
g⁻¹(y) = <span>(y + 5)/3</span>
g⁻¹(x) = <span>(x + 5)/3</span>
