Which of the following situations would combine to make zero?
a.
julia took two math practice tests last month. she plans to take two more tests later this month.
b.
chris walks four blocks west to the grocery store. after buying groceries, he walks four blocks east.
c.
manuel spent five hours exercising this weekend. he also spent five hours watching television.
d.
amy drives for three hours along an interstate highway. she then drives for three hours along county highways.

B

Step-by-step explanation:

He’s walking four blocks west first which means he’s coming from the east and then he walks four blocks back east

x = 17

step-by-step explanation:

in the given figure, two triangles are inscribed in a circle where ∠bae ≅ ∠dae which makes the side be and de equal so we can write it as:

3x - 24 = x + 10

solving this equation for x to get:

3x - x = 10 + 24

2x = 34

x = 34/2

x = 17

therefore, the value of x = 17.

the answer is d

the answer is in the first quadrant, which make the y-int positive.

since the dots are going down, therefore the correlation is negative

i hope it is right.
