Answer:

  1. 18x - 9 = 72
  2. 3(6x - 3) = 72
  3. x = 45

Step-by-step explanation:

Apply the distributed property:

  1. Apply the distributed property: 3/5 × 30x = 18x, 3/5 × 15 = 9
  2. Re-write the equation: 18x - 9 = 72
  3. 18x - 9 = 72 is an option listed, so that's one of the answers.

See the other options:

  1. Another option that looks like it could be the answer is 3(6x - 3) = 72
  2. Apply the distributed property like we did above, so it now looks like this: 18x - 9 = 72
  3. This is the same as what we got above, so it is also an answer.

Solve:

  1. Add 9 to each side, so it now looks like this: 18x = 81
  2. Divide each side by 18 to cancel out the 18 next to x. It should now look like this: x = 4.5
  3. x = 45 is an option listed, so that's one of the answers.

I hope this helps!

The accepted value of the average distance between Earth and the moon is 384, 467 km. If a scientist measures that the moon is 3

Answer:

Percentage error is 0.0024 %

Step-by-step explanation:

Initial average distance between Earth and moon = 384467 km  

Distance measure by the scientist = 384476 km

Total variation in the distance calculation = 384476 – 384467 = 9 km.

Now we can find the percentage by dividing the variation in distance from the initial measurement and then multiply with hundred.

Percentage error = ( 9 /  384467 ) × 100 = 0.0024 %

Any idea ? I need help
trasher [3.6K]
Use the Pythagorean Theorem:
a^2 + b^2= c^2

a= one side= 68 mi
b= second side= 80 mi
c= hypotenuse= Greenville to Columbia mi


a^2 + b^2= c^2

68^2 + 80^2= c^2
square each number

4,624 + 6,400= c^2

11,024= c^2
take square root of both sides

104.995 mi= c


ANSWER: The distance from Greenville to Columbia is 104.995 miles (rounded to 105 miles).

Hope this helps! :)
