Answer:
it would be 32
Step-by-step explanation:
you would add them all up then divide it by five
A + b = 147....a = 147 - b
5.85a + 4.40b = 786
5.85(147 - b) + 4.40b = 786
859.95 - 5.85b + 4.40b = 786
-5.85b + 4.40b = 786 - 859.95
- 1.45b = -73.95
b = -73.95 / -1.45
b = 51 <== she used 51 lbs of type B coffee

Answer:
Step-by-step explanation:
Multiply both sides of the equation by 10:
9x²+7x-2=0
Write 7x as a difference:
9x²+ 9x-2x -2 =0
Factor the expression:
9x x (x+1)-2x-2 = 0
9x x (x+1) - 2 (x+1) =0
Then seperate them into possible cases:
(x+1) x (9x-2) = 0
x+1 = 0
9x - 2= 0
The equation has 2 solutions:
x1 = -1
x2 =
