Which pair of planets exerts the strongest gravitational force, Saturn and Jupiter, or Mars and Jupiter. Explain
dsp73
Dear Noora7939, the pair of planets that exerts the strongest gravitational force is Saturn and Jupiter, since we know that both Jupiters are the same mass, we'll excuse that. Since the laws of gravity says that the bigger the mass the stronger the gravitational pull, Saturn has the stronger gravitational pull since Saturn is bigger than Mars.

If a number is an element of the set of real
kvasek [131]

Answer:

Option (A)

Step-by-step explanation:

A set of real numbers is a combination of both rational and irrational numbers.

But the elements in the sets of rational and irrational numbers will be different.

In short, rational and irrational number sets are the two subsets of real numbers.

Hence, the number is an element of either the set of rational numbers or the set of irrational numbers.

Option (A) is the correct option.

A student solved 6x+4=2(x−8) in four steps as shown:
mr_godi [17]
The first thing you should do is solve the equation yourself.

1) Distribute the 2.  
6x + 4 = 2x – 16

2) Next, you'll want to get the x's on one side. So add -2x to both sides.
6x + 4 + -2x = 2x + -2x - 16
4x + 4 = -16

3) Now subtract 4 from both sides
4x + 4 – 4 = -16 – 4
4x = -12

4) Finally, divide both sides by 4
4x/4 = -12/4
x = –3

To solve this problem all you need to do is look back out you work, and figure out the correct solution. The answer the question is The student made an error in Step 1.
