Answer:
Step-by-step explanation:
First cross multiply:
2(x+2)=2x-2
Then Simplify:
2x+4=2x-2
Finally, Solve:
2x-2x=4+2
Ans: No Solution
Answer:
distance is 6.4 units
Step-by-step explanation:
use a^2+b^2=c^2 to find the hypotenuse which is the distancr
you can count the sides base is 4 and height is 5 Square the numbers
16+25= c^2
41=c^2
find the square root of 41 to get rid of the squared
which is 6.40 so 6.40= c and c is the distance
Answer: 138x + 27
Step-by-step explanation:
First you distribute the 3, creating 102x +27.
Then you combine like terms, creating 138x + 27
You can't do anything else so that's your answer.
Answer:
y = 3x - 5
Step-by-step explanation:
y = mx + b
y - b = mx
-b = mx - y
b = -mx + y
b = -3(1) -2
b = -5
Answer: The rock would still weigh 90lbs
Step-by-step explanation:
No, weight has being proven to reduce by the further you move from the center of the Earth. But since even the tallest buildings in the world or tallest mountains are a tiny fraction of the Earth’s radius, the difference in weight won’t be something that can be measured as it’s a tiny fraction. So the mass of the rock doesn’t change what changes is the gravitational force ( g ). So the rock would still end up weighing 90lbs even at the top of the tower because it is still within the earths atmosphere.
