It is -7/2 when the variables are substituted
Answer:
see explanation
Step-by-step explanation:
The 2 equations are
x + 2y = 8 → (1)
2x + 4y = 20 → (2)
(x-8)*2/5=2
0.4x - 3.2=2
0.2x-1.6=1
0.2x=2.6
x=2.6*5
x=13

Step-by-step explanation:
Given,
Radius of a cylinder = 2 ft
Height of the cylinder = 7 ft
Therefore, volume of the cylinder



Answer:
The distance between the two points is 8 units
Step-by-step explanation:
In the given figure
∵ The coordinates of the 2 points are (4, 5) and (4, -3)
∴ x1 = 4 and y1 = 5
∴ x2 = 4 and y2 = -3
∵ Their x-coordinates are equal
→ That means the distance between them is vertical
∴ The length of the vertical distance between two points is
the difference between the y-coordinates of the points
∵ The distance between them = Iy2 - y1I
∵ y1 = 5 and y2 = -3
∴ The distance between them = I-3 - 5I
∴ The distance between them = I-8I
→ Remember absolute value gives always positive values
∴ The distance between them = 8 units
∴ The distance between the two points is 8 units
