I don't know why it is faced that way but help plz

Nady [450]

Answer: x > 5

Step-by-step explanation: You need to isolate x. First, distribute the 1/2 into the parentheses. You will get:

4x + x + 2 > 12

Combine like terms.

5x + 2 > 12

Subtract 2 from each side.

5x > 10

Divide by 5 on each side.

X > 2

Since x is by itself, that is the answer.

Answer:

A. f + y ≤ 11

17f + 287 ≤ 242

Step-by-step explanation:

[] Let f be football players and v be volleyball players.

-> The total time must be less than or equal to 242 seconds.

-> If football players talked for 17 seconds, we can write it as 17f.

-> If volleyball players talked for 28 seconds, we can write it as 28v.

[] Coming back to the first point I made, the total time must be less than or equal to 242 seconds.

-> 17f + 28v ≤ 242

[] This is going to be a part of our system of inequalities

-> Because of this, we rule out the following options.

B & D - the football players talk for 17 seconds, not the volleyball players

C - not less than or equal too, only less than

[] This leaves us with the option of A.

-> The first part of it also works. If 11 players can talk to the crowd, then the total of f and v must be equal too or less than 11.

Have a nice day!

I hope this is what you are looking for, but if not - comment! I will edit and update my answer accordingly.

Points N and R both lie on circle O. Line segment RQ is tangent to the circle at point R.

ANEK [815]

Answer:

Perimeter ΔRON = 18.66 units

Step-by-step explanation:

Complete Question has these information given as well:

Circle with center O
RN = QN
RQ = $5\sqrt{3}$
ON = 5 units
RQ is tangent

Now, we draw an image according to the information given. THe image drawn is attached.

Looking at the figure, we can say the perimeter of triangle RON would be:

RON = OR + ON + RN

We know according to tangent theorem, QN = QR

RN is equal to that as well and RN = $5\sqrt{3}$

Now,

OR and ON is the radius, which is "5"

Perimeter of RON = 5 + 5 + $5\sqrt{3}$ = 10 + $5\sqrt{3}$ = 18.66 units

Perimeter ΔRON = 18.66 units

Is (4,3) a solution to 2x-y <4?

olga55 [171]

Sub the point into the inequality
2(4)-3<4
8-3<4
5<4
Therefore, no, it is not a solution because 5 is not less than 4
Hope this helps!
