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

"The angles of a triangle are 3x, (2x+20), and (5x-40).Find the angles. Show that the triangle is an equilateral triangle." Angles of a triangle add up to 180. 3x + 2x + 20 + 5x - 40 = 180 {sum of angles equals 180} 10x - 20 = 180 {combine like terms} 10x = 200 {added 20 to both sides} x = 20 {divided both sides by 10} Substitute 20, in for x ...

6xx + 2x - 20 = 0 the above quadratic equation is in standard form, with a=6, b=2 and c=-20 to solve the quadratic equation, by using the quadratic formula, copy and paste this:

You can put this solution on YOUR website! 2x-5y=20-5y=-2x+20 y=-2x/-5+20/-5 y=2x/5-4 When x=0 then: y=-4 When y=o then:

You can put this solution on YOUR website! Solve 5^(2x)=20 2xlog5 = log20 2x=log20/log5 2x=1.86135... x= 0.9306765581...

2x + 20 = 5x - 34 Now solve for x... Subtract 2x and add 34 to each side and get 54 = 3x Now divide by 3 ...

You can put this solution on YOUR website! 2*10 + y = 20 20 + y = 20 y = 0 when x is 10 y is 0, meaning that 10 is the y-intercept of the line 2x+y=20
