Answer:
Step-by-step explanation:
This drawing illustrates the
equation: -3x – 7 = 5.
Since:
(-x + -x + -x) + (-1 + -1 + -1 + -1 + -1 + -1 + -1) =
(1 + 1 + 1 + 1 + 1) → (-3x) + (-7) = (5) →
-3x – 7 = 5.
To reduce the equation and find x:
[add 7 to both sides to isolate the constant term on the right side]
-3x – 7 + 7 = 5 + 7 →
-3x = 12 →
[divide both sides by -3 to cancel out the coefficient of -3 in -3x to get x]
-3x / -3 = 12 / -3 →
x = -4
Answer:
16642.1 feets
Step-by-step explanation:
Given :
Elevation of Mt. Wilson = x
If the elevation of snow crest = y
Snow crest = 11,508.21 feet higher than Mt. Wilson
Hence, y = 11,508.21 + x
The elevation of Mt. Wilson, x = y - 11,508.21 feets
From the table, elevation of Snow crest = 28,150.31 feets = y
Hence, The elevation of Mt. Wilson, x = y - 11,508.21 feets
x = 28,150.31 - 11,508.21
x = 16642.1 feets
Answer:
The area of the shape is .
Step-by-step explanation:
The shape in the graph is a composite figure is made up of several simple geometric figures such as triangles, and rectangles.
Area is the space inside of a two-dimensional shape. We can also think of area as the amount of space a shape covers.
To calculate the area of a composite shape you must divide the shape into rectangles, triangles or other shapes you can find the area of and then add the areas back together.
First separate the composite shape into three simpler shapes, in this case two rectangles and a triangle. Then find the area of each figure.
To find the area of a rectangle, we multiply the length of the rectangle by the width of the rectangle.
The area of the first rectangle is
The area of the second rectangle is
The area of a triangle is given by the formula where <em>b</em> is the base and <em>h</em> is the height of the triangle.
The area of the triangle is
Finally, add the areas of the simpler figures together to find the total area of the composite figure.
