What is the first step in solving: 2x + 9 = -11
O Eliminate the coefficient
Eliminate the constant
O Simplify
O Check the solution
O Distribute

Distribute

Step-by-step explanation:

In this problem it the first thing to do is to combine like terms, which can be done through distributing -9 to both sides. We will then get 2x=-20

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).
