Find each sum or difference. round to the place value of the less precise measurement : 8.53 m – 1.8 m
a.
10.3 m
b.
7 m
c.
6.73 m
d.
6.7 m

The correct option is d.

Step-by-step explanation:

The given expression is

Taking out the common factor.

Least precise value means the value approximated to least decimal place.

Therefore the correct option is d.

25

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.
