Step-by-step explanation:

1/3= 1/2 hr.

×2 ×2

=

2/3=1hr

2/3

25/4

step-by-step explanation:

call segment cd's length x. because dc and ab are parallel, angle acd and cab, so triangles adc and abc are similar and we can set up the equation x / ac = ac / ab, or x / 5 = 5 / 4 and x = 25/4.

y = x + 95

y = 42 + 95

y=137 mm hg
