Answer:
c. none of the above
Step-by-step explanation:
(-6+3)= -3
2--3=2+3=5
5+4c cant add them since they arent like terms
final answer 5+4c and that option isnt here
4x - 2(0.5x-1) =14
4x - 1x +2 = 14
3x + 2 = 14
X= 4
Plug that into second equation to get y
The earth is 93 million miles away from the sun. 93 million times 10 is 930,000,000 away. Mars is currently 141.6 million miles from the sun. Assuming the planets were in a straight line you would subtract from 141.6 million miles the 93 million miles so that would put us within 48,600,000 miles of Mars. So the answer is we would be closest to Mars.
So first write out the expression:

take two 10's from the top to cancel with the two 10's on the bottom.
3.9/1.3 is 3.
The answer is 3*10^3
Answer:
None
Step-by-step explanation:
There is no integer equivalent to 91/2, integers can't have a decimal.
However, I assume you would like me to answer 9.5, even though it isn't an integer.
