Step 4. With x=35, then 2x-20=70-20=50 and 3x-10=105-10=95. Step 5. Since the triangle has angles 35, 50, and 95 where one angle is greater than 90 degrees then the triangle is an obtuse triangle by definition I hope the above steps were helpful.

For tutors: simplify_cartoon( 2x+10+x+2x-20=180 ) If you have a website, here's a link to this solution.

1.)5In(2x) =20 Evaluate logarithmic 1. Algebra -> Exponential-and-logarithmic-functions -> SOLUTION: Express the answer in terms of e. Then use a caculator to obtain a decimal approximation, correct to two decimal places, for the solution.

4x + 10 = 2x + 20 {used distributive property} 2x + 10 = 20 {subtracted 2x from both sides} 2x = 10 {subtracted 10 from both sides} x = 5 {divided both sides by 2} 4x = 20 {substituted 5, in for x, into 4x} Selma is 5 now Fred is 20 now For more help from me, visit: www.algebrahouse.com

Question 78285: If the measures of the three angles of a triangle are x, 2x - 20, and 3x - 10, then what is this type of triangle? why? Answer by checkley75(3666) ( Show Source ): You can put this solution on YOUR website!

You can put this solution on YOUR website! Start by taking the ln of each side of the equation to "undo" the "e^":

You can put this solution on YOUR website! 3x+4y=17 6y-2x=-20 Rewrite this as 3x+4y=17-2x + 6y=-20 To eliminate the x terms, you need to find a "common number" between the x coefficients.

In In one region, the pipeline follows the path given by y=2x+20, where each unit on the grid represents 1 km. A town in that region is centred at (50,5) and has a radius of 5 km. New bylaws require that the pipeline not be within 55 km of an urban area. a) How close does the pipeline come to the town?----y=2x+20 --> 2x - y + 20 = 0
