Answer:
Ratio
Step-by-step explanation:
Voltage measurement of batteries involves ratio level of measurement because it has a significant zero i.e. zero voltage of the battery will mean no voltage. The mathematical operations of multiplication, division, addition and subtraction are meaningful in ratio level of measurement. The mathematical operations of multiplication, division, addition and subtraction on voltage measurement of batteries are meaningful.
Thus, voltage measurement of batteries involves ratio level of measurement.

Answer:
b=5
Step-by-step explanation:
10 = -2b + 4b
Combine like terms
10 = 2b
Divide each side by 2
10/2 = 2b/2
5 = b
Answer:
z = 7
Step-by-step explanation:
9z + 4 / 5 - 8 = 5.4
Add 8 to both sides.
9z + 4 / 5 = 13.4
Multiply 5 by both sides.
9z + 4 = 67
Subtract 4 from both sides.
9z = 63
Divide both sides by 9.
z = 7
