I. 2x2 – 19x + 45 = 0
II. y2 – 14y + 48 = 0
I. 2x2 – 19x + 45 = 0 => 2x2 – 10x – 9x + 45 = 0 => 2x(x – 5) – 9(x – 5) = 0 => (x – 5) (2x – 9) = 0 => x = 5, 4.5 II. y2 – 14y + 48 = 0 => y2 – 8y – 6y + 48 = 0 => y(y – 8) – 6(y – 8) = 0 => (y – 8) (y – 6) = 0 => y = 8, 6 Hence, x < y.
32 of (16/8) of (30/24) of (120/x) = 30
5 × 14 + 100 ÷ 4 = 62 + ?
18(1/3) + 9(2/3) – 10(1/3) = 1(2/3) + ?
What is the place value of 6 in 367892141?
32 + 26 × (484 ÷ 44) + 450 ÷ 9 = ?
132 × 3 ÷ 11 + 67 − ? = 64 ÷ 8 × 2
√(1889 – 125) + √(841 – 165) = ?
40% of 1820 + 80% of 630 = 90% of 1280 + ?
17% of 250 + ? = 108
Simplify-
x + 3(y + x – 2) – (x + y).
