Adult humans have approximately 2.6 x 10^13 red blood cells and 3.92 x 10^10 white blood cells. about how many times greater is the number of red blood cells than white blood cells?
a. 660
b. 1,300
c. 1,500
d. 6,600

hint: which coefficient is a multiple of 360°?

step-by-step explanation:

1) the property is   ixi = a ⇔x = a   o x = -a

4(x-5)+3= 15⇒4x-20+3 = 15⇒4x-17= 15⇒4x = 15+17⇒4x = 32⇒x =32/4= 8

4(x-5) +3= -15⇒4x-20 +3 = -15⇒4x-17= -15⇒4x =-15+17⇒4x = 2⇒x =2/4= 1/2

the values are x =8 and x = 0,5
