Rewrite the equation below using ONLY the symmetric property of equality:2x + 5 = 3x -7

12 = x

Step-by-step explanation:

Symmetry here would involve subtracting the same quantity from both sides of the equation.

Starting with 2x + 5 = 3x -7,

subtract 2x from both sides.  This yields

                            5        = x - 7

Adding 7 to both sides yields

                   12 = x

$8

step-by-step explanation:

it is pretty much backwards.

you take the 4x2 multiply that, and that is = $8

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).
