Answer:

1/3D + 10 = 3/5D

10 = 3/5 D ÷ 1/3 D

10 = 3D/5 ÷ D/3

10 = 3D/5 × 3/D

(btw there is no cross cancleing, just straight up multiply.)

10 = 9D/5D

cancel the 10 and 5D to make 10 to 2, and 5d to D.

Next, cancel both the D's (the 9d and the d (the d becomes 1 which is just 9 over nothing. translates to just a simple 9.))

there is a 2 on the opposite side of the 9, so bring it under 9. so 9/2

then divide to get 4.5

4.5 is the answer!

Mark me brainliest if it is correct!

Find the missing length of the triangle.

Rus_ich [418]

Using the Pythagorean theorem the formula would look:

$c^2=b^2+a^2\Longrightarrow3.4^2=3^2+a^2$

Now just solve for a.

$a^2=3.4^2-3.0^2\Longrightarrow a=\sqrt{3.4^2-3.0^2} \\ a=\sqrt{11.56-9}=\sqrt{2.56}=\boxed{1.6}$

Side a is 1.6 inches long.

Hope this helps.
