Answer:

x= 4

Step-by-step explanation:

We do like:

5x+2(1-x)=2(2x-1)

5x + 2 -2x = 4x -2

or 3x +2 = 4x -2

3x-4x +2 = -4x+4x -2

or -x +2= -2

and -x+2 -2 = -2 -2

or -x = -4

and x = 4 is the solution.

Have a good day.

Answer:

Answer

5.0/5

Let's find the unit rate stemming from $18 for 4 games:

$18

------------- = $4.50/game

4 games

Let's do the same for $27 for 6 games:

$27

------- = $4.50/game (same as before)

6 g

Thus, the const. of prop. is $4.50/game, and the cost function is

C(x) = ($4.50/game)x, where x is the # of games played.

Answer:

Step-by-step explanation:

By inscribed angle theorem

$(15x-23)\degree = \frac{1}{2}[360\degree-(91+135)\degree]\\(15x-23)\degree = \frac{1}{2}[360\degree-226\degree]\\(15x-23)\degree = \frac{1}{2}[134\degree]\\(15x-23)\degree = 67\degree\\15x-23 = 67\\15x = 67+23\\15x = 90\\x= \frac{90}{15}\\x=6$
