Answer:
x = 0, 9/2
Step-by-step explanation:
6x^2 - 27x = 0 (original)
3x(2x - 9) = 0 (factor out GCF of 3x)
|
v
(solve each factor (3x and 2x - 9) for x)
3x = 0
x = 0
2x - 9 = 0
2x = 9
x = 9/2
The answer would be £20, you would turn this into a proportion and doing that you'd have 70/100=14/x(x being the full cost) then you cross multiply and doing so you get 1400=70x and 1400 divided by 70 equals 20, so your answer is £20
Answer:
50 gallons 20%
50 gallons 30%
Step-by-step explanation:
If x is gallons of 20% moonshine, and y is gallons of 30% moonshine, then:
x + y = 100
0.20x + 0.30y = 0.25(100)
Solve the system of equations using substitution or elimination. Using substitution:
0.20x + 0.30(100 − x) = 0.25(100)
0.20x + 30 − 0.30x = 25
5 = 0.10x
x = 50
y = 50
Answer:
no solution
Step-by-step explanation:
Given
8(3x - 6) = 6(4x + 8) ← distribute both sides
24x - 48 = 24x + 48 ( add 48 to both sides )
24x = 24x + 96 ( subtract 24x from both sides )
0 = 96 ← not possible
This indicates the equation has no solution
