I'm pretty sure the area of this triangle is 30 m squared. Can someone please tell me if I am right?

It is 30m.. Because you do 10x6=60 then divide it by 2 which is 20.. and hxb/2 is the formulas so.

Brad bought a used bike for $8 more than half of its original price. Brad paid $40 for the bike. What was the original price?

$\huge\boxed{\$64}$

Start by writing a formula, where $x$ is Brad's purchase price and $y$ is the original price.

$40=8+\frac{y}{2}$

Subtract $8$ from both sides.

$32=\frac{y}{2}$

Multiply both sides by $2$ .

$\boxed{64}=y$

First multiply each term by 24(the common denominator found by 8×3) to remove the fractions and make things easier.
$24(5) + 24( \frac{x - 2}{3} ) = 24( \frac{x + 3}{8} )$
This will give you,
$120 + 8(x - 2) = 3(x + 3)$
Then just continue to simplify and isolate the variable.
$120 + 8x - 16 = 3x + 9$
$8x + 104 = 3x + 9$
$5x = - 95$
$x = - 19$
