<h3>Answer:</h3>
- 28/100 = 7/25
- 100/28 = 25/7
<h3>Explanation:</h3>
The wording "the ratio of A to B" means A/B.
Here, "the ratio of the weight of silicon to the weight of crust" means ...
... (28 tons)/(100 tons)
Canceling common factors (and common units), this is ...
... 28/100 = 7/25
___
Then "the ratio of the weight of crust to the weight of silicon" means ...
... (100 tons)/(28 tons) = 100/28 = 25/7
<span>8 + 3{x - 2[x + 5(x + 3)]}.
=</span><span>8 + 3{x - 2[x + 5x + 15]}
=</span>8 + 3{x - 2[6x + 15]}
=8 + 3{x - 12x -30}
=8 + 3{- 11x -30}
= 8 - 33x - 90
= - 33x - 82
