What is the best estimate for the mass of a bicycle about 10 kilograms about 100 grams or about i kilogram or 10 grams

The best estimate for the mass of a bicycle is about 1 kilogram.

Step-by-step explanation:

The standard International System of Units (SI) unit of mass is the kilogram denoted by kg .

It is used world wide for measuring the mass of an object .

Smaller units of the mass is gram it is denoted by g .

Therefore the best estimate for the mass of a bicycle is about 1 kilogram .

i have no clue at all sorry

step-by-step explanation:

so firstly, we need to isolate the y variables to be able to solve these inequalities. firstly, add 0.5x on both sides of the first inequality and subtract 1.5x on both sides of the second inequality:

now since the slope is positive for the first inequality, this means that the line going upwards belongs to the first inequality, and the line going downwards belongs to the second inequality.

next, since y ≥ in the first inequality, this means that the shaded region will be above the first inequality's line, thus shading regions a and b.

next, since y ≤ in the second inequality, this means that the shaded region is going to be below this line, thus shading regions a and c.

since both lines shade region a, this means that region a is the solution.
