Explanation: 3/5 = 24/x, so x = 40.
Explanation: 25 + 20 = 45.
Explanation: The slope is the coefficient of x, which is 3.
Explanation: a - b = 5 - (-3) = 5 + 3 = 8.
Explanation: 75% of 200 = 0.75 × 200 = 150.
Explanation: HCF(12,18) = 6.
Explanation: x - 1 = 4, so x = 5.
Explanation: 2.5 + 3.7 = 6.2.
Explanation: Area = ½πr² = ½ × (22/7) × 49 = 77.
Explanation: 3x = 18, so x = 6.
Explanation: 8!/6! = 8 × 7 = 56.
Explanation: Any number raised to 0 equals 1.
Explanation: Width = area/length = 36/9 = 4.
Explanation: 1/4 - 1/8 = 2/8 - 1/8 = 1/8.
Explanation: LCM(4,6) = 12.
Explanation: x = ±√49 = ±7.
A 3/4
B 7/10
C 75/100
D 1/4
Explanation: 0.75 = 75/100 = 3/4.
Explanation: Distance = √((3-0)² + (4-0)²) = √(9+16) = √25 = 5.
Explanation: x² × x³ = x^(2+3) = x⁵.
