Answer: division model
Step-by-step explanation:
Since we have been given that the number of students that are playing tag at recess = 36 and, it is 6 times as those that are playing hopscotch.
The Division model shows this compat. Let number of students playing hopscotch be y. From the question,
y = 36/6 = 6
Therefore, the division model shows this comparison.
Answer:
Step-by-step explanation:
- Mother's age = m
- Son's age = s
<u>3 years later:</u>
- m + 3 = 4(s + 3) ⇒ m = 4s + 12 - 3 = 4s + 9
<u>3 years ago:</u>
- m - 3 = 2(s + 8) ⇒ m = 2s + 18 + 3 = 2s + 21
<u>Solve for s by substitution:</u>
- 4s + 9 = 2s + 21
- 2s = 12
- s = 6
<u>Find the value of m:</u>
Mother is 33 and son is 6
