For Joe's illness, the doctor gave him a prescription of 28 pills. He needs to take 4 pills the first day, and then 2 pills each
kiruha [24]

Answer:

12 days.

Step-by-step explanation:

I looked at it this way:

He has to take 4/28 pills the first day, so it's 28-4=24. Then I divided 24 by 2.

In simpler terms:

28-4=24

Help I need to get this done I have 15 questions
ivanzaharov [21]

Answer:

8 cm

Step-by-step explanation:

(See the image attached for details)

  • The blue segment measures 15 cm
  • The green segment measures 7 cm
  • The green and yellow segment when added form the blue segment
  • So: ? + 7 = 15

Solve:

? + 7 = 15

Subtract 7 on both sides:

? + 7 = 15

   -7     -7

? = 8 cm

Therefore, the yellow segment, or the missing side length, measures 8 cm.
