Answer:
Simplifying
x = -25
Step-by-step explanation:
Reorder the terms:
10x + -6(5 + 2x) = 20
10x + (5 * -6 + 2x * -6) = 20
10x + (-30 + -12x) = 20
Reorder the terms:
-30 + 10x + -12x = 20
Combine like terms: 10x + -12x = -2x
-30 + -2x = 20
Solving
-30 + -2x = 20
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '30' to each side of the equation.
-30 + 30 + -2x = 20 + 30
Combine like terms: -30 + 30 = 0
0 + -2x = 20 + 30
-2x = 20 + 30
Combine like terms: 20 + 30 = 50
-2x = 50
Divide each side by '-2'.
x = -25
The surface area of the cylindrical ring is given by
πdh
where d is the diameter and h is the height:
π•6.3•48 = 950.02
The answer is C. 950.02 in^2
Answer:
The converse of Pythagorean Theorem states:
If the square length of the longes side of a triangle is equal to the sum of the squares of the other two sides, then it's a right triangle.
We use the converse of Pythagorean Theorem to prove that a triangle is a right triangle. It's like the inverse use of the theorem. Often, this theorem is used to find the length of a side of a triangle when we already know it's a right triangle. However, when we don't know that is a right triangle, we use the converse to prove it.

Answer:
Step-by-step explanation:
<u>Full charge can be expressed as equation:</u>
- c = 2.5 + 0.75m, where c- charge, m- miles
<u>The limit for charge is $13, then we got inequality:</u>
- 0.75m + 2.5 ≤ 13
- 0.75m ≤ 9.5
- m ≤ 9.5/0.75
- m ≤ 12.66
Option B: 10 is correct as the only number satisfying the inequality
