Answer 2

Finding the Roots of Equations

To find the roots of the given equations, we need to isolate the variable on one side of the equation. Let's solve each equation step by step:

a) 3x = 17

To find the value of x, we can divide both sides of the equation by 3:

3x/3 = 17/3

Simplifying, we get:

x = 17/3

Rounding this value to the nearest thousandth, we have:

x ≈ 5.667

b) 9y = 20

To find the value of y, we can divide both sides of the equation by 9:

9y/9 = 20/9

Simplifying, we get:

y = 20/9

Rounding this value to the nearest thousandth, we have:

y ≈ 2.222

c) 15s = 37

To find the value of s, we can divide both sides of the equation by 15:

15s/15 = 37/15

Simplifying, we get:

s = 37/15

Rounding this value to the nearest thousandth, we have:

s ≈ 2.467

d) 0.11x = 0.63

To find the value of x, we can divide both sides of the equation by 0.11:

(0.11x)/0.11 = 0.63/0.11

Simplifying, we get:

x = 0.63/0.11

Rounding this value to the nearest thousandth, we have:

x ≈ 5.727

Therefore, the roots of the given equations, rounded to the nearest thousandth, are:

a) x ≈ 5.667 b) y ≈ 2.222 c) s ≈ 2.467 d) x ≈ 5.727

Please note that these values are rounded and may not be exact.
