Answer:
1). Simplifying
Y = -5x + 45
Reorder the terms:
Y = 45 + -5x
Solving
Y = 45 + -5x
Solving for variable 'Y'.
Move all terms containing Y to the left, all other terms to the right.
Simplifying
Y = 45 + -5x
(hope this kind of helps) :D
Answer: Choice B) The expression (10-2x)(30-2x)x represents the volume of the box
----------------------------------------------------
----------------------------------------------------
The original width is 10 inches. The width reduces to 10-2x inches after we cut off the top two corners of the rectangle. We can think of it as taking 10 and subtracting off two copies of x like so: 10-x-x = 10-2x
Similarly, the length goes from 30 inches to 30-2x inches. This time we're taking off the top and bottom corners (focus on either side it doesn't matter).
The height of the box is x inches due to this portion being folded up.
Volume of box = (width)*(length)*(height)
Volume of box = (10-2x)(30-2x)x
Note: the units for the answer are in cubic inches which can be written as "in^3" (inches cubed).
Answer:
15
Step-by-step explanation:
To get the next number you have to subtract by 9, 51-9=42, 42-9=33, 33-9=24, and so 24-9=15. The pattern is n-9 (n=previous number) and the answer is 15
Answer:
C.
Step-by-step explanation:
C. is correct bc it makes the most sense out of all of them just check my work by dividing by 2.
