8/27
Step-by-step explanation:

<h2>
Option C is the correct answer,</h2>
Step-by-step explanation:
The distance of planet Jupiter from the Sun is approximately 7.8 x 10⁸ kilometers.
Distance from Jupiter to Sun = 7.8 x 10⁸ kilometers
The distance of planet Saturn from the Sun is 1.5 x 10⁹ kilometers.
Distance from Saturn to Sun = 1.5 x 10⁹ kilometers
Difference in distances = 1.5 x 10⁹ - 7.8 x 10⁸ = 15 x 10⁸ - 7.8 x 10⁸
Difference in distances = 7.2 x 10⁸ kilometers
Option C is the correct answer,
100-20 round the last numbers so they have a 0 at the end so 4 or under is 0 and 5 or higher is 10 so 100 - 20 is 80
Answer:
300
Step-by-step explanation:
I think its 300 but if I'm wrong then XD I Don't know
<u><em>Answer:</em></u>
The missing term is 3x²
<u><em>Explanation:</em></u>
Addition and subtraction can only take place between like terms.
<u>For two terms to be like</u>, both the variable and its degree must be the same in both terms
<u>Now, consider the given terms:</u>
First term is 7x² has the variable x with degree 2
The resulting term is 10x² has the variable x with degree 2
This means that the missing term is ax²
We need to get the value of "a"
<u>This is done as follows:</u>
ax² + 7x² = 10x²
x²(a+7) = 10x²
a+7 = 10
a = 10-7
a = 3
Therefore, the missing term is 3x²
Hope this helps :)
