Step-by-step explanation:
Solve for 'x'.
To solve for 'x', isolate 'x'.
2.8a + 3.2x + 1 = 16.6
Subtract 1 from both sides. {Subtraction property of equality}
2.8a + 3.2x = 16.6 - 1
2.8a + 3.2x = 15.6
Subtract 2.8 a from both sides.
3.2x = 15.6 - 2.8a
Now, divide both sides by 3.2. {Division property of equality}
SOLUTION:
We are to calculate the shaded area of the given shape.
CONCEPT:
This is a triangle that a rectangle was cut out from.
To calculate the shaded area of the given shape, we are to find the area of the triangle and then subtract the area of the recangle that was cut out.
The shaded area = Area of the triangle - Area of the rectangle
