Um pls help heres the photo attachment.

i need to test sum it

Before I start, I'm going to tell you to not trust my answer 100%. I'm not good at this type of stuff but I'd like to try.

First, convert the fractions and decimals to the same units. I think it would be easier to convert to decimal.

Brazil: 2.8

India: 0.175

Russia: 0.02

United States: 0.044

Now that we have everything in decimal, we order it from least to greatest. (Least is at the top.)

Russia

United States

India

Brazil

I really hope this helps, and again, you might wanna look at the other answer because this may not be correct.

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
