1. P = IRT....for T
P / (IR) = T
2. A = 2(L + W)....for W
A/2 = L + W
(A/2) - L = W
3. y = 5x - 6...for x
y + 6 = 5x
1/5y + 6/5 = x....or (y + 6)/5 = x
4. 2x - 3y = 8....for y
-3y = -2x + 8
y = 2/3x - 8/3
5. not exactly sure of the equation here.....(x + y) / 3 = 5 ?? or 3(x + y) = 5 ??
6. y = mx + b....for b
y - mx = b
7. ax + by = c....for y
by = c - ax
y = (c - ax)/b...or y = (c/b) - (ax/b)
Answer:
A = 30
Step-by-step explanation:
x = 5
y = 10
A = xy - 20
substitute 5 and 10 in the place of x and y
(5*10) - 20
50 - 20
30
A = 30
(8,2.4) because you can have half of a day not negative days
