The correct answer is C
If x + y + 3 = 0, then find the value of x3 + y3 – 9xy + 9.
25% of 60 × 15% of 120 = 30% of (?)
3.2% of 500 × 2.4% of ? = 288
√4096 + 4/5 of 780 − ? = 296
2850 ÷ 2.5 - ? × 42 = 300
The sum of two numbers is 16 and their product is 63. The sum of their reciprocal is equal to:
5 + 2 × 3 ÷ (3 × 2) ÷ 4
128 ÷ 22 × ? = 15% of 300 ÷ 9
175 + 24% of 450 = 350 + ?
