Line segment TV is a midsegment of ∆QRS. What is the value of n in the triangle pictured?
Elis [28]

Answer:

D. 3.2

Step-by-step explanation:

Mid-segment Theorem of a triangle states that the Mid-segment in a triangle is half of the third side of the triangle.

Based on this theorem, we have: TV = ½(RS)

TV = 3n - 2

RS = n + 12

Substitute

3n - 2 = ½(n + 12)

Multiply both sides by 2

2(3n - 2) = (n + 12)

6n - 4 = n + 12

Collect like terms

6n - n = 4 + 12

5n = 16

Divide both sides by 5

5n/5 = 16/5

n = 3.2

which values of x and y are solutions to the open sentence? 4y ≥ 3x 2 a. x = 3, y = 0 b. x = 4, y = 3 c. x = 6, y = 5 d. x = 7,
boyakko [2]
4y ≥ 3x + 2

Plugging in the values in the options, then the required values are when x = 6 and y = 5, then
4(5) ≥ 3(6) + 2
20 ≥ 18 + 2
20 ≥ 20

Someone please help me with #28 and #30 I got myself super confused.
bogdanovich [222]

<u><em>Question 28:</em></u>

S-2\pi r^2=2\pi rh                     Subtract 2\pi r^2 on both sides

\frac{S-2\pi r^2}{2\pi r} =h         Divide 2\pi r on both sides

<u><em>*(Answer)*=</em></u>  \frac{S-2\pi r^2}{2\pi r} =h


<u><em>Question 30:</em></u>

a*t=v_{1}+v_{0}                  Multiply t on both sides

a*t+v_{0} =v_{1}                 Subtract v_{0} on both sides

<u><em>*(Answer)*=</em></u> a*t+v_{0} =v_{1}
