Answer:
2.75x + 114 = 320.25
x = $75
Step-by-step explanation:
2.75x + 114 = 320.25
number of hours of labor (2.75) times the cost per hour of labor (x) + cost of parts (114) = total cost (320.25)
2.75x + 114 = 320.25
subtract 114 from both sides
2.75x = 206.25
divide both sides by 2.75
x = 75
------------------------
check the math:
2.75(75) = 114 = 206.25 + 114 = 320.25
The answer is 4.2 because you have to replace r with -14.1 and s with 18.3. After that you subtract them and you get 4.2
Answer:
Step-by-step explanation:
The Earth, Sun and Moon form a right triangle.
By the definition of cosine in a right triangle we can write that
cos x ° = adjacent side /hypothenuse = y/ distance Moon Sun
Since we measured the angle x, and the distance y we can use algebra to find the unknown distance between the moon and the Sun.
distance Moon Sun = y/cos x°
