If 1.2 kilograms of rust form on a bridge in five days, what should be the rate of reaction in grams per hour? (recall that a bar over the number means that zero is significant.)
100(first zero has bar over it) g/hr
0.05 g/hr
0.010 g/hr
10(zero has bar over it) g/hr

im pretty sure it would be 5 am, hope that , and give brainliest and guys if this is right then press the button and give 5 stars

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
