Answer:
RSM = 56.4
Step-by-step explanation:
RSM + MST = RST
RSM + 33.6= 90
Subtract 33.6 from each side
RSM + 33.6 - 33.6= 90-33.6
RSM= 90-33.6
RSM = 56.4
Answer:C(x) = 2000+ 0.05 x
Step-by-step explanation: Cost (C) = fixed cost + (cost per pencil x number of pencils)
Since:
Fixed cost: $2000
Cost per pencil : $0.05
Replacing with the values given:
C(x) = 2000+ 0.05 x
Where x is the number of pencils manufactured.

You have to watch 30 movies to earn a free movie pass.
Step-by-step explanation:
Given,
Points earned for each movie = 2 points
Current points = 40 points
Free movie pass = 100 points
Let,
x be the number of movies you have to watch.
2*number of movies + current points = 100
Subtracting 40 from both sides
Dividing both sides by 2
You have to watch 30 movies to earn a free movie pass.

Answer:
k = - 3
Step-by-step explanation:
Given that x = 3 is a solution then it satisfies the equation, that is
2(3)² - 5(3) + k = 0
2(9) - 15 + k = 0
18 - 15 + k = 0
3 + k = 0 ( subtract 3 from both sides )
k = - 3
Answer:
x=2, y= 21
Step-by-step explanation:
y = 6x + 9
y = 7x + 7
Since both equations are equal to y, we can set them equal to each other
6x+9 = 7x+7
Subtract 6x from each side
6x+9-6x = 7x -6x+7
9 = x+7
Subtract 7 from each side
9-7 = x+7-7
x=2
Now we need to find y
y = 6x+9
y = 6(2) +9
y = 12 +9
y = 21
