Answer:
x=21
Step-by-step explanation:
The two angles form a straight line so they add to 180
6x+2+52 = 180
6x+54= 180
Subtract 54 from each side
6x+54-54 = 180-54
6x= 126
Divide by 6
6x/6 =126/6
x = 21
$105 because 35+45+25=105.

z is directly proportional to x: z = kx.
If z is directly proportional to x and inversely proportional to y, then z = Kx/y.
When x= 6 and y = 6, z is 12. Find the constant of proportionality, K:
12 = K(6/6), or K = 12
Then, in general, z = 12x/y.
What is z when x=13 and y=10? z = 12(13)/(10) = 15.6 (answer)
Answer:
Use dimensional analysis to answer each of the following questions. To find the distance light travels in a year for part a, convert sec to yr by using unit ratios with min, hr, and days in their denominators. Thus, a light year is approximately 5,874,589,152,000 mi
