Solve the equation. Write your answer as an integer or simplified fraction.

<u>Corrected question :</u>

Solve the equation. Write your answer as an integer or simplified fraction.

  • 8n - 7 (n - 2) = 18

<u>Required Solution :</u>

The given equation,

  • 8n - 7 (n - 2) = 18

★ Multiplying -7 into (n - 2),

>> 8n - 7 × (n - 2) = 18

>> 8n - 7n + 14 = 18

★ On substracting 7n from 8n we gets,

>> n + 14 = 18

★ Now transposing 14 which is in L.H.S. into R.H.S. (Remember that sign would be . So 14 would be -14),

>> n = 18 - 14

>> n = 14

★ Therefore,

  • Value of n is 14.

PLEASE HELP ASAP! PLS
11Alexandr11 [23.1K]

Answer:

ok so it would take more effort to lift the 1 newton that is 4 m

Step-by-step explanation:

Work is done when a an object with a certain weight is moved at a given distance;

It is the product of force and distance and therefore varies directly to both distance and force.

Work = Force × distance;

For a 4 N box 0.5 m;

Work = 4 × 0.5

       = 2 Joules

For a 1 N box 4 m

Work = 1 × 4

       = 4 Joules

Therefore, Lifting a 1 N box for 4 m, will take more work

hope this helps
