Plz someone i need 5 and 6. idk how to do them but i know that is the right answer. who ever gets 10 points

5. (Step-By-Step Instructions):

(w/h^2x703) = BMI            Write equation

(w/60^2x703) = 20.5           Substitute the values to the equation

(w/3600)x703 = 20.5           Simply the exponent

(703w/3600) = 20.5           Multiply 703 to w/3600

703w = 73800                   Multiply 3600 to 20.5

w =  104.97866                Divide 703 to 73800

w = 105                           Round the number to the nearest whole number

Sorry I cant do 6

300

step-by-step explanation:

28-600w < 300

28-600w > 300

600-28w < 300

600-28w > 300
