Answer:
6
Step-by-step explanation:
Evaluate 4 z^2 - 3 z - 4 where z = 2:
4 z^2 - 3 z - 4 = 4×2^2 - 3×2 - 4
Hint: | Evaluate 2^2.
2^2 = 4:
4×4 - 3×2 - 4
Hint: | Multiply 4 and 4 together.
4×4 = 16:
16 - 3×2 - 4
Hint: | Multiply -3 and 2 together.
-3×2 = -6:
16 + -6 - 4
Hint: | Group the negative terms in 16 - 6 - 4 together and factor out the minus sign.
16 - 6 - 4 = 16 - (6 + 4):
16 - (6 + 4)
Hint: | Evaluate 6 + 4.
6 + 4 = 10:
16 - 10
Hint: | Subtract 10 from 16.
| 1 | 6
- | 1 | 0
| 0 | 6:

Answer:
2.56
Step-by-step explanation:
Monday: 2 * 2.21 = 4.42
Tuesday: 4.42 + 0.39 = 4.81
Wednesday: 4.81 - 1.76 = 3.05
Thursday: 3.05 - 1/5 * 3.05 = 3.05 - 0.61 = 2.44
Friday: 2.44 + 0.12 = 2.56
16%
64/400 = 16/100 = .16 = 16%
Answer:
12 5/8
Step-by-step explanation:
25 - 12 3/8
we need to borrow 1 from the 25 and make it a fraction
make it 8/8
24 8/8 - 12 3/8
12 5/8
