Answer: Elisa
Step-by-step explanation:
Elisa withdrew $20 at a time from her bank account and withdrew a total of $160. The number of times she made a withdrawal will be:
= $160 / $20
= 8 times
Frances withdrew $49 at a time from his bank account and withdrew a total of $196. The number of times she made a withdrawal will be:
= $196 / $49
= 4 times.
From the calculations above, we can see that Elisa made the greater number of withdrawals.
Answer:
|-45|
Step-by-step explanation:
In mathematics, the absolute value of a real number is the numeric value of the number, regardless the sign, either this is positive or negative.
The absolute value function can be definied as:
- |a|=a si a ≥0
- |a|=-a si a <0
Using this definition, we have:
|-21| = -(-21) = 21
|14| = 14
|30| = 30
|-45| = -(-45) = 45
Therefore, the expression |-45| has the greatest value.
