I. 5x2 – 18x + 16 = 0
II. 3y2 – 35y - 52 = 0
I. 5x2 – 18x + 16 = 0 => 5x2 – 10x – 8x + 16 = 0 => 5x(x – 2) – 8(x – 2) = 0 => (x – 2) (5x - 8) = 0 => x = 2, 8/5 II. 3y2 – 35y - 52 = 0 => 3y2 – 39y + 4y - 52 = 0 => 3y (y – 13) + 4(y – 13) = 0 => (y – 13) (3y + 4) = 0 => y = 13, -4/3 Hence, x = y or the relationship cannot be established.
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).
