Answer:
b.
It's too short. Write at least 20 characters to explain it well
Answer:
16 edges.
Step-by-step explanation:
We will use Euler's polyhedron formula to solve for the edges of our convex polyhedron.
Euler's polyhedron formula is: , where,
V= Vertices of polyhedron,
F= Faces of polyhedron,
E= Edges of polyhedron.
Let us substitute V=6 and F=12 in Euler's formula to find number of edges of our polyhedron.
Let us subtract 18 from both sides of our equation.
Therefore, our convex polyhedron will have 16 edges.
The linear inequality is
16S + 10T ≤ 100
T = Number of t-shirts
S = Number of shorts
For 2 shorts,
32 + 19T ≤ 100.
<h3>What is inequality?</h3>
It shows a relationship between two numbers or two expressions.
There are commonly used four inequalities:
Less than = <
Greater than = >
Less than and equal =
Greater than and equal=
We have,
Cost of shorts = $16
Cost of t-shirts = $10
Total amount to spend = $100
Number of shorts to purchase = S
Number of t-shirts to purchase = T
The linear inequality is given as:
16S + 10T ≤ 100
Since S = 2,
16 x 2 + 10T ≤ 100
32 + 10T ≤ 100
10T ≤ 100 - 32
1OT ≤ 68
T ≤ 6.8
This means he can buy 6 or less than 6 t-shirts.
Thus,
The linear inequality is
16S + 10T ≤ 100
T = Number of t-shirts
S = Number of shorts
For 2 shorts,
32 + 19T ≤ 100.

Answer:
is b
Step-by-step explanation:
Answer:
A. Infinitely many solutions
Step-by-step explanation:
x − 2y = 5 | × (- 2)
2x − 4y = 10
- 2x + 4y = - 10
2x - 4y = 10
----------------------- +
- 2x + 2x + 4y - 4y = - 10 + 10
0 = 0
A. Infinitely many solutions
