1 kg = 1000 g....so 2.5 kg = (2.5 * 1000) = 2500 grams
it cooks 30 minutes per 500 g.....2500/500 = 5...so there are 5 thirty minute periods ....(5 * 30) = 150 minutes....plus the extra 20 minutes....(150 + 20) = 170 minutes....so your answerr is 2 hrs 50 minutes
Answer:
x₁ = 4
x₂ = 2
Step-by-step explanation:
x² - 6x + 8 = 0
x² - 2x - 4x + 8 = 0
x(x - 2) - 4(x - 2) = 0
(x - 4)(x - 2) = 0
x - 4 = 0 => x₁ = 4
x - 2 = 0 => x₂ = 2
