-4t = -15 + 3
Divide both sides by -4.
T= -15/4 -1
Convert 3 (1/2) into a mixed fraction first and then multiply it by 3:
3(1/2) * 3
(7/2) * 3
21/2
10 (1/2) = answer
Answer:
- x + y ≤ 20,000
- y ≤ 5,000
- x ≥ 2y
Step-by-step explanation:
Given:
Total amount = $20,000
Assume
Government bonds = x
Municipal bonds = y
Computation:
1. Invest total money
x + y ≤ 20,000
2. invest no more than $5,000 into municipal bonds
y ≤ 5,000
3. at least twice as much into government bonds.
x ≥ 2y
Answer:
40
Step-by-step explanation:
- Use the rules of PEMDAS: 48 ÷ 6 = 8
- Plug 8 in: 64 - 8 × 4 + 8
- 8 × 4 = 32
- Plug 32 in: 64 - 32 + 8
- 64 - 32 = 32
- Plug 32: 32 + 8
- 32 + 8 = 40
I hope this helps!
Answer:
False
Step-by-step explanation:
6 + (-7)n = 34
Plug in -7 for n and see if it's true:
6 + (-7)(-7) = 34
6 + 49 = 34
55 = 34
No, it's not true, so the mystery number is not -7.
