X/5 - 3 < 5....add 3 to both sides
x/5 < 5 + 3
x/5 < 8....multiply both sides by 5, eliminating the 5 on the left side
x < 8 * 5
x < 40 ...... ur solution
* and just so u know, x/5 is the same as (1/5)x....in case u wanted to solve it a little different........1/5x < 8...u would divide both sides by 1/5.....x < 8 / (1/5).....x < 8 * 5/1......x < 40....u will still get the same answer
The sum of interior angles in a regular octagon equals 1080 degrees.
So 1080 / 8 = 135
z = 135
You need to fine the radius by dividing the circumference by 2 and then multiply that by pi (3.14) or (22/7)
1) Subtract the upper right 10 ft square from the overall 18 ft square.
.. (18 ft)^2 -(10 ft)^2 = 224 ft^2
3) The area of this is the sum of the areas of a rectangle 11 in by 7 in, and a triangle with base 7 in and height 5 in.
.. (11 in)*(7 in) +(7 in)*(5 in)
.. = (7 in)*(11 in +2.5 in) = 94.5 in^2
4) The central rectangle is 10 cm by 14 cm; the remaining triangle has a height of 7 cm and a base of 24 cm.
.. (10 cm)*(14 cm) +(24 cm)*(7 cm)/2
.. = 140 cm^2 +84 cm^2
.. = 224 cm^2
You find out how much 15% of 48,000 is which is 7,200. Then you do 7,200+48,000=55,200.
So your answer would be 55,200
