Answer 2

Let's solve each equation step-by-step:

A) 15x = 0.15 To solve for x, divide both sides of the equation by 15: x = 0.15 / 15 x = 0.01

B) 3.8:y = 4 To solve for y, multiply both sides of the equation by 3.8: 3.8 * y = 4 y = 4 / 3.8 y ≈ 1.0526 (rounded to 4 decimal places)

C) 3a + 8a = 1.84 Combine the like terms on the left side of the equation: 11a = 1.84 Now, isolate a by dividing both sides by 11: a = 1.84 / 11 a ≈ 0.1673 (rounded to 4 decimal places)

D) 2t + 5t + 3.18 = 25.3 Combine the like terms on the left side of the equation: 7t + 3.18 = 25.3 Now, isolate t by subtracting 3.18 from both sides: 7t = 25.3 - 3.18 7t = 22.12 Finally, divide both sides by 7 to solve for t: t = 22.12 / 7 t ≈ 3.16 (rounded to 2 decimal places)

So, the solutions for each equation are as follows: A) x = 0.01 B) y ≈ 1.0526 C) a ≈ 0.1673 D) t ≈ 3.16
