Answer:

Step-by-step explanation:

Let's solve the first equation for either x or y. I'll do it for x.

Begin by subtracting 5y.

Now divide by 5.

Simplify:

Now substitute x in the second equation for this value.

Distribute;

Add 6

Combine like terms;

Divide by -10.

Answer:
Step-by-step explanation:
Both distances are in the scientific notation:
Earth - Sun = 9.3 * 10^7 miles
Saturn - Sun = 8.87 * 10^8 miles
8.87 * 10^8 - 9.3 * 10^7 =
= 88.7 *10^7 - 9.3 * 10^7 =
= 79.4 * 10^7 = 7.94 * 10 ^8 = 794,000,000 miles
Answer: Saturn is 7.94 * 10^8 miles farther from Sun than Earth is.
16x³ - 54
= 2(8x³ - 27)
= 2(2x - 3)(4x² + 6x + 9) ← answer
