For this case by similarity of triangles we can use the following relationship:
(x) / (9) = (5) / (15)
We clear the value of x:
x = ((5) / (15)) * (9)
Rewriting:
x = (1/3) * (9)
x = 3
Answer:
The value of x for this case is:
x = 3

Step-by-step explanation:
the answer would be C
because it is taking the total hours ( x) and subtracting 1 ( the first hour that cost $7
and then multiplying x by the $5 per minute and then adding the $7 for the first hour
Step-by-step explanation:
y=kxz
13=k x 5 x 8
13= 40k
K=13/40
a. y=13/40 x 4 x 10
y=13/40 x 40
y=13
b. 20=13/40 x x x 12
20=13/40 x 12x
20=<u>156x</u>
40
20 x 40=156x
800=156x
X=<u>800</u>
156
X=<u>200</u>
39
X=5 5/39
C. 15=13/40 x 6 x z
15=<u>78z</u>
40
15x40=78z
600=78z
Z=<u>600</u>
78
Z=<u>100</u>
3
Z=7 9/13
