Solve the following expression when x=9

3- x/3 +2x

18

Step-by-step explanation:

1. Replace X with its value (9)

3- 9/3 + 2•9

2. Using PEMDAS, divide 9 by 3

3 - 3 + 2•9

3. Multiply 2 and 9

3 - 3 + 18

4. Subtract 3 from 3

18

Your answer is 18

no association

step-by-step explanation:

if you have eyes and you can use them efficiently you can see that it just looks like random dots like do a line of best fit and like they're so spread out it's such a weak association you might as well consider it nonexistent

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).
