    MHB Solving Inequality 4x-12≤6x+20

    Hello, I'm working on solving linear equalities (with equations) and can anyone help with the below question. I know the answer is -16, but I can't figure out the steps that gets it to this. 4x-12≤6x+20 Once I've evened out the x's on both sides and got this to 2x, I'm then left with -12...

    MHB Solve for the angles in a triangle

    Hi, Could someone check that I'm right with this one, or put me right! I've worked the value out as x=30 and y (2x) = 60. I've come to this as I think it's an isosceles triangle so the base angles would be equal. Am I right? Thank you!
