X + x + x + 20 + 10 = 180
(combine like terms)
3x + 30 = 180
3x=180-30
3x=150
x=150/3
x=50

Statement 'k less than 3.5'.
Less than means the number is subtracted from another number.
k less than 3.5 is given by, 
Therefore, The required expression is 
Rewrite
(4)(3.63) * (10^4)(10^-4)
multiply
14.52 * (10^4)(10^-4)
multiplication of the coefficient is the addition of the exponent
so 4 -4 is 0
14.52
Hope this helps :)
