One way in which to approach this problem would be to treat it as an equation of ratios and to cross multiply:
<span>[(4x + 15) / 5x)] = 1/2 could be written as:
4x + 15 1
----------- = ---
5x 2
Then 8x + 30 = 5x
3x = -30, and so x = -10 (answer). Be certain to check this answer through substitution!

3.10/155= 0.02 } subtract = 0.07 more
7.65/85= 0.09 }
Answer:
the length=2.3m and breath=90cm find the perimeter and area of rectangle
Answer:
see below
Step-by-step explanation:
-1.5
Integers have no fractional parts
-1.5 is -1 1/2 which has a fractional part
The rest are whole numbers and integers
Tan^2x + 1 + tanx - 3 = 0 tan^2x + tanx - 2 = 0 (tanx + 2)(tanx - 1) = 0 tanx = -2 or tanx = 1 x = 2.034 radians or x = 5.176 radians or x = pi/4 radians or x = 5pi/4 radians
