For the following equations, draw a picture of the tiles on an Equation Mat. Then use “legal” moves to simplify and solve for the variable. a. -2+x = -x+2

b. 2+3x = x+7

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

step-by-step explanation:

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c

1 + (6 / x - 1)

step-by-step explanation:

divide using polynomial division.

explanation:

previous steps have made pa≅ pb ≅ st ≅ su. setting the compass width to ab allows you to make tu the same length. then δstu ≅ δpab by the sss congruence postulate, and ∠p ≅ ∠s by the reason cpctc.
