2. Round off the decimal: (a) 3.153 to the nearest tenths (b) 10.126 to the nearest hundredths (c) 5.0014 to the nearest thousandths (d) 5.992 to the nearest tenths (e) 21.805 to the nearest hundredths (f) 3.1089 to the nearest thousandths

(a)3.15,(b)10.1,(c)5.0,(d)6.00,(e)21.8,(f)3.1

u = -(6/7)w

step-by-step explanation:

place all values with 'u' on one side of the equation.

4u + 8w = - 3u + 2w

4u + 3u = 2w - 8w

further simplify the equation by solving the addition and subtraction.

7u = - 6w

make 'u' the independent variable by placing its co-efficient on the right-hand side.

u = - (6/7)w

answer: 4 (:
