Answer:
2%
Step-by-step explanation:
True measurements = 400 meters
Observed measurements = 392 meters
% error = change in measurements / true measurements × 100/1
= (400 - 392) / 400 × 100
= 8/400 × 100
= 0.02 × 100
= 2%
Percentage error of Beth measurements = 2%

Answer:
x=5
Step-by-step explanation:
1) Group like terms which will then make the equation 4x-2(x-5)=5x-5
2) Expand the equation (multiply) which will make it 4x-2x+10=5x-5
3) Add similar elements; 2x+10=5x-5
4) Subtract 10 from both sides; 2x=5x-15
5) Subtract 5x from both sides; -3x=-15
6) Divide by 3; x=5
