2y + 3x = 10
2x + 3y = 10
Answer:
Step-by-step explanation:
Given : Twice the abscissa increased by three times the ordinate is ten.
To find : which equation represent Twice the abscissa increased by three times the ordinate is ten.
Solution : We have abscissa = x.
Ordinate = y.
According to given statement :
Twice the abscissa = 2 * x .
Three times the ordinate = 3 * y.
Twice the abscissa increased by three times the ordinate is ten :
2 * x + 3 * y = 10.
Therefore, This equation 2 * x + 3 * y = 10 is correct.
Which expression can be used to determine the greatest possible volume of the cardboard box?
A) (x−7)(x−11)x
B) (7−2x)(11−2x)x
C) (11−7x)(11x−7)
D) (7x−11)(7−11x)
Answer:
Option B
Step-by-step explanation:
Given is a rectangle with width 7 and length 11.
From each corner of the rectangle a square of length x is cut and foled to make a box
Now for the open box we made, height = x
width = rectangle width - 2 times d
= 11-2x
Length = rectangle length-2x
Hence volume of box
=lwh
= (7-2x)(11-2x)x
Answer: B)
Step-by-step explanation:
Given: The length of the cardboard = 11 in.
The width of the cardboard =7 in.
If a box is created without a top from a piece of cardboard, but cutting out square corners with side length x, then the dimensions of box will be:-
Width (w)=
length (l)=
Height (h)=
Now, volume of rectangular box is given by :-
Hence, the expression can be used to determine the greatest possible volume of the cardboard box is given by :-
Step-by-step explanation:
This problem is not about percent or relative change, but about absolute change. Its solution is very simple:
Absolute change, or
change = new value - old value
= 56 - 45 = 11 (increase)
