Answer:
134
Step-by-step explanation:
The ratio of Type O donors to total donors was ...
... 37 : (37+43) = 37 : 80
So, 37/80 is the fraction of total donors that were Type O.
Then the number of Type O donors expected in a group of 290 is ...
... (37/80) · 290 = 134.125 ≈ 134
Answer:
multiply (x-1) to both sides and then subtract three from both sides
3 = (x-1)(x+1)
3 = (x^2 -1)
0 = x^2 - 4
(x-2)(x+2) = 0
x = 2
x = -2
Step-by-step explanation:
The equation you had:
6x + 5y = 45
Solve for Y:
5y = (-6x) + 45 divide by 5
y = (-6/5)x + 9
y = -1 1/5x +9
