Mariana walked 3/10 mile to the park. Later, she walked 1/4 mile to a friend's house. Then she walked 2/5 mile home. How many miles did Mariana walk in all?

19/20 of a mile.

Step-by-step explanation:

The common denominator is 20 so we times the first one by 2 the second one by 5 and the last one by 4. (Both numerator and denominator.)

You will end up with this

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.

i'm not sure how to show the work for this

answer : c and d or 4(29 + 6)

4(29) + 4(6)
