Answer:
x = 3, y = 1
Step-by-step explanation:
2y = 2x - 4, so y = x - 2. Substituting this into the bottom equation and solving for x:
x - 2 + 3x = 10
4x - 2 = 10
4x = 12, so x = 3 and y = 1.
The algebraic expression of the situation above is 4x - 100 = 400
<h3>How to form an algebraic expression?</h3>
Let
the amount of ice cream they serve in July = x + 100
the amount of ice cream they serve in June = x
They served twice as many customers in august as they did in June.
Therefore,
the amount of ice cream they serve in August = 2(x)
the amount of ice cream they serve in August = 2x
Therefore,
2x + x + x + 100 = 400
4x - 100 = 400
4x = 500
x = 500 / 4
x = 125

We know that
volume of a cuboid=length*width*height
in this problem
we have
volume=(18 cm)³
so
volume=18*18*18 cm³
the dimensions of the cuboid are
length 18 cm
width 18 cm
height 18 cm
18 cm x 18 cm x 18 cm
Answer:
Lower Quartile: 62
Upper Quartile: 81
Interquartile Range: 19
Step-by-step explanation:
To find the lower quartile, you want to find the median from the minimum to the median.
49, 55, 62, 64, 67
The median of this is 62. Therefore, 62 is the lower quartile.
To find the upper quartile, you want to find the median from the median to the maximum.
76, 79, 81, 82, 83
The median of this is 81. Therefore, 81 is the upper quartile.
To find the interquartile range, you subtract the upper and lower quartile.
81-62=19
The difference is 19. Therefore, the interquartile range is 19.
