Zhang tried to evaluate an expression step by step -x/3 / 2/y

Step 1 = -x/3 / 2/y

Step 2 = -x/3 / y/2

Step 3 = -xy/6

B Step 2

C Step 3

D Zhang did not make a mistake

b

step-by-step explanation:

p ÷ r = tan(x)

step-by-step explanation:

given that there is a figure below shows a right triangle: a right triangle is shown with hypotenuse equal to q units and the length of the legs equal to p units and r units.

graph is missing so i will create the graph as per given information.

the angle between the legs having lengths p units and q units is y degrees. the angle between the legs having lengths r units and q units is x degrees.

now we need to find about what is p ÷ r equal to.

so we can use trigonometric ratio tan(x)=[altitude]/[base] to find the value of p ÷ r, because p is the altitude and r is the base.

p ÷ r=tan(x)

hence final answer is p ÷ r=tan(x).

1 + (6 / x - 1)

step-by-step explanation:

divide using polynomial division.
