Answer:
is d
Step-by-step explanation:
2.13%
Inaccurate measurement = 5.5cm
Actual measurement = 5.62cm
Difference= actual - inaccurate
=> 5.62 - 5.5
Therefore, the measurement Jocelyn obtained is off by 0.12cm (difference)
Note: error = difference
% diff = error÷ actual measurement × 100
= 0.12/5.62 × 100
% diff. = 2.13 (to the nearest decimal place)
x=4
where y =3x
8x-3x=20
5x=20
5x/5=20/5
