Lana = x
Pam = 0.5x - 0.05
Cheryl = 0.5x - 0.05 + 3.10

Total 89$ = Lana + Pam + Cheryl

89 = x + 0.5x - 0.05 + 0.5x - 0.05 + 3.10
89 = 2x + 3
89 - 3 = 2x
86 = 2x
86/2 = x
43 = x

then Pam = 0.5(43) - 0.05
= 21.50 - 0.05
= 21.45

Cheryl = 21.45 + 3.10
= 24.55

Someone please convert this equation to slope intercept form: 2x - 3y = 6?
IgorLugansk [536]
Slope y-intercept form is: y=mx+b

All you have to do is rearrange the equation:

2x-3y=6
2x=6+3y
2x-6=3y

now divide both sides by 3
(2x/3)-(6/3)=(3y/3)

and it becomes
y= \frac{2}{3}x-2x

Bonus: you can plug in any two values for x and y and you can see both equation gives the same answer!

Answer:

ASA

Step-by-step explanation:

If 2 angles and the included side of one triangle are congruent to 2 angles and the included side of the other triangle, then the triangles are congruent.

The included side is the side between the vertices of the 2 triangles.

Here

∠ S = ∠ W ( 1 angle )

∠ R = ∠ X ( 2 angles )

RS = XW ( side between the 2 angles )

Thus the 2 triangles are congruent by the ASA postulate

Identify the segment bisector of RS. Then find RS
Elena-2011 [213]

Answer:

RS = 32

Step-by-step explanation:

M is the bisector of RS , then

RM = MS , that is

6x - 2 = 3x + 7 ( subtract 3x from both sides )

3x - 2 = 7 ( add 2 to both sides )

3x = 9 ( divide both sides by 3 )

x = 3

Then

RS = 6x - 2 + 3x + 7 = 9x + 5 = 9(3) + 5 = 27 + 5 = 32
