Step 2...first error...when distributing through the parenthesis, u multiply, not add.
4(2x - 4) = 8 + 2x + 8 =
8x - 16 = 16 + 2x <== correction
Answer:
If your money earns a 5 percent interest rate, it will triple in 23 years (115 divided by 5 equals 23).
Step-by-step explanation:
Rate = 10/2 = 5 trees per hour
150trees/5 trees per hour = 30 hours
the answer is D = 30 hours
1. y = 2/3x - 5
2. 4x - 6y = 30
Divide 2. by 2
3. 2x - 3y = 15
Substitute 1. into 3.
4. 2x - 3(2/3x - 5) = 15
5. 2x - 2x + 15 = 15
6. 15 = 15
False. There are an infinite number of solutions.
