Find the value of Z for the triangles
kolbaska11 [484]

Answer:

z = 17.5

Step-by-step explanation:

segment RX is an angle bisector and divides the opposite side into segments that are proportional to the other 2 sides, that is

\frac{RS}{RT} = \frac{SX}{TX} , substitute values

\frac{15}{z} = \frac{6}{7} ( cross- multiply )

6z = 105 ( divide both sides by 6 )

z = 17.5

A rectangular parking lot has a perimeter of 310 meters. The length is 5 meters more than 4 times the width. What’s is the lengt
max2010maxim [7]

Answer:

w=30  l=125

Step-by-step explanation:

Perimeter =2l+2w

p=310

w =width

4w+5 = length(4 times plus 5 the width)

2(4w+5) + 2w = 310

8w+10 = 2w =310

10w=300

w=30    

30*4=120    120+5=125    l=125

2(125)+ 2(30)=  250+60 =310

6. What is the y-value to the solution of<br> y = 5x -4<br> y = 2x + 8?
Angelina_Jolie [31]

Answer:

y = 16, don't know if I'm 100% right but hope this helps.

Step-by-step explanation:

since they both equal Y they may be equal to each other

Then you would subtract 2x from both sides canceling it out on one side

2x + 8 = 5x - 4

-2x         -2x

This would make the equation 8 = 3x - 4

next you add the 4 from both sides

8  = 3x - 4

+4         +4

This will leave you with 12 = 3x

now you divide 3 from both sides and 12/3 = 4 makes X = 4

next you take (4) and plug it in to one of the equations

y = 2(4) + 8

y = 8 + 8

y = 16
