1. AB=5.3, BC=?, AC=6.7 2. AB=21, BC=4.3, AC=? 3. AB=?, BC=18.9, AC=23 4. AB=6 3/4, BC=?, AC=10 5. AB=3x, BC=5x, AC=8 6. AB=3(x+7), BC=2(x-3), AC=50 How would you solve these and draw them?

Hello. Do you have experience solving simple systems of equations? That's an algebra technique involving substitution. Drawings depend on context. Could A,B,C represent triangle sides?

Please share what you've tried or thought about so far. What has your class been doing recently? Thank you!

Context is needed. Are A, B, and C points on a line? Do you know their order along that line? Is there a picture given?

If the order is A, B, C, then AB + BC = AC. Do you see that? So if you know one of the three lengths, you can find the other. And if you know all of them in terms of a variable, you can write an equation to solve for the variable.

But if you don't know the order, or if they don't have to be on a line, then you can't know the answers.

It would be helpful to show an image of the entire problem as given to you.
