Answer:
The value of x in the 2nd quadrant is always negative.
Step-by-step explanation:
There form four zones in the coordinate plane by placing the coordinate axes i.e. X-axis and Y-axis. The top right zone is called the 1st quadrant and 2nd, 3rd and 4th quadrants are the zones obtained by rotating in anticlockwise about the origin.
Since the 2nd quadrant is placed at the top left zone, so, we have to move in the negative x-direction along or parallel to the X-axis and to move in the positive y-direction along or parallel to the Y-axis.
Therefore, the value of x in the 2nd quadrant is always negative.

Answer:
The cousins have 4 bags of white marbles and 4 bags of pink marbles.
Step-by-step explanation:
If x is the number of bags with white marbles and y is the number of bags with pink marbles, we can write the following system:
x + y = 8 -- Equation 1
5x + 7y = 48 -- Equation 2
5x + 5y = 40 -- Equation 3 (Multiply Equation 1 by 5)
2y = 8 -- (Subtract Equation 3 from 2)
y = 4 -- (Divide both sides by 2)
x + 4 = 8 -- (Substitute y = 4 into Equation 1)
x = 4 -- (Subtract 4 from both sides)
Answer:
length = 28 cm
width = 4 cm
Step-by-step explanation:
perimeter = (2 x length) + (2 x width)
perimeter = 64 cm
ratio of length and width = 7 : 1
total ratio of length and width is 8 = a
length = (7/8)a
width = (1/8)a
perimeter = (2 x 7/8)a + (2 x 1/8)a = (14/8)a + (2/8)a = (16/8)a = 2a = 64
a = 64 : 2 = 32 cm
length = 7/8 x 32 = 28 cm
width = 1/8 x 32 = 4 cm
The answer is c, $1.92 .
if you multiply 0.08 by 24, you get that answer.
