Questions like this ("how much higher is x than y?") are answered by computing the ratio of the two quantities.
In fact, for example, the answer to "how much higher is 10 than 5?" is 2, because 10:5 = 2, and indeed 10 is twice as much as 5.
So, we have
So, the melting temperature of platinum is about one time and a half higher than the melting temperature of gold.

Answer:
16x^2 + 9x^2 + 9x + 13.
Step-by-step explanation:
6x^3 + 8x^2 – 2x + 4 +10x^3 + x^2 + 11x + 9
Bringing like terms together:
= 6x^3 + 10x^3 + 8x^2 + x^2 - 2x + 11x + 4 + 9
= 16x^2 + 9x^2 + 9x + 13. (answer).
Answer:
Step-by-step explanation:
if Jim eats r apples and Maria eats 3times as Jim then we can represent the number of times Maria eats as 3r
Together, the both eat 96 apples that is:
r + 3r = 96 apples - this is the equation for this situation.
Solving further
r + 3r = 96apples
4r = 96 apples (divide through the equation by 4)
4/4 r = 96/4 apples
Then
r = 24 apples
Which means that Jim eats 24 apples while Maria eats 3 * 24 apples = 72 apples.
