The equations classified according to the number of solutions are given as follows:
- No solution: -3(3q + 4) = -6q + 12
- One solution: -2(3n - 4) = -6n - 4
- Infinitely many solutions: 8z - 4 = 8z - 4
<h3>How many solutions does the equation 4(2z - 1) = 8z - 4 has?</h3>
We solve the equation, hence:
4(2z - 1) = 8z - 4
8z - 4 = 8z - 4
Equivalent, hence they have infinitely many solutions.
<h3>How many solutions does the equation -2(3n - 4) = -6n - 4 has?</h3>
-2(3n - 4) = -6n - 4
-6n + 8 = -6n - 4
0 = -12, which is false, hence it has no solutions.
<h3>How many solutions does the equation -3(3q + 4) = -6q - 12 has?</h3>
-3(3q + 4) = -6q + 12
-9q - 12 = -6q + 12
3q = -24
q = -8.
One solution.

For this case, the first thing you should keep in mind is the following conversion:
1 hectare = 2.5 Acres
Applying the conversion we have:
(12) * (1 / 2.5) = 4.8 hectares
Answer:
the area in is:
4.8 hectares
Equation
Total = movies plus songs.
Givens
Total = 100
Movies = 48.4
Songs Cost = x
Number of Songs = 40
Solve
100 = 48.4 + 40x Subtract 48.4 from both sides.
100 - 48.4 = 40x
51.6 = 40x Divide by 40
51.6 / 40 = x
1.29 = x
Conclusion
Each song cost $1.29
Answer:

Step-by-step explanation:
well you know that the perimeter is the sum of all sides
so we have
so the sides are:
So there you are.
Answer:
Conversely, if n is divisible by 5, then n is the sum of five consecutive integers. In particular, this gives n = 5m + 10 = 5(m + 2) and, since m + 2 is an integer, this shows n is divisible by 5
Step-by-step explanation:
