That's an isosceles triangle lying on its side.  The base angles (on the left) are marked equal, so we know the sides opposite them are equal.

That means that  . . . x+4 = 3x-8

Subtract 'x' from each side . . . 4 = 2x-8

Add  8  to each side . . . 12 = 2x

Divide each side by 2 . . . <em>6 = x</em>

The bill for Dino's lunch was $19.45. He wanted to leave 20% of the total bill as a tip. How much should the tip be?​
Salsk061 [2.6K]

You could multiply 19.45 by 0.2 to solve for it, but if you're not using a calculator, then 19.45/5 would be much more convenient and easier.

0.2 is 1/5 in fraction form, which is why we can do that.

19.45/5 = 3.89

Dino should leave $3.89 as a tip.
