<u>Solving in steps</u>
- 1. ⇒ z + (-0.72) - (-0.72) = -2.5 - (-0.72)
- 2. ⇒ z = - (2.5 - 0.72)
- 3. ⇒ z = - 1.78
The student's mistake was adding (-0.72) instead of - (-0.72) or 0.72
Answer: 1. 3/8-1/4=1/8
2. 3/8+1/4=5/8
3. x=5/8
Step-by-step explanation: 1. you have to subtract 3/8 by 1/4 because you have to use the largest number to subtract for the smallest number so 3/8-1/4=1/8
2. Add by adding 3/8 by 1/4 because you have to find the value of x so 3/8+1/4=5/8
3. look at number 2. and the answer is x= 5/8

Answer:
Domain: 0 t 40 Range: 0 V(t) 200
Step-by-step explanation:
The domain is greater than or equal to 0 and less than or equal to 40 because in 40 months, she will lose all her money ($5 x 40months = $200) since she loses 5 dollars per month. Not to mention, time can't be negative in any situation. For the range, the value has to be greater than or equal to zero and less than or equal to 200 because she only has $200, the more time she spends using the phone, the more money she will lose over the course of the month( limiting her time). I hope this helps!
