Answer:

27.55

Step-by-step explanation:

So 49.7 + 15.8 + 22.7 + 15.1 + 32.2 + 39.1 +27.7 + 18.1 = 220.4

220.4 / 8 = 27.55

{\huge{\boxed{\mathbb{ANSWER\:WITH\:EXPLANATION}}}

Hello there, first we can place our equation, which you have stated

2d+9=19, this algebra, in algebra we want to find the exact value of the variable, or have the variable on one side of the equation.

First we can subtract 9 with both sides of the equation giving us the result of 2d=10, this can also be represented as 2\cdot d=10, now just divide both sides of the equation by 2, our answer is d=5.
