Answer:
5cm
Step-by-step explanation:
Convert 1.5m into cm to make it easier to solve.
1.5m --> 150cm (*100)

Answer: $4.50
Step-by-step explanation:
125=21.50+23x
This is the equation to find this situation since 125 was given and it equals the left over and the spent money.
Subtract 21.50 from both sides first to be epic.
103.5=23x
Very cool! Divide both sides by 23 to get 4.5=x
It would be: 21 * (6.3 * 10⁻⁴)
= 132.3 * 10⁻⁴
= 1.323 * 10⁻²
In short, Your Answer would be: 1.323 * 10⁻²
Hope this helps!
