Question 1.
A young male elephant is 85 inches tall. A young female elephant is 57 inches tall. If the female elephant grows to 102 inches tall, how tall will the male elephant be if they grow the same amount?
Answer:
Number of inches tall a young male elephant grows = 130.

Explanation:
Number of inches tall a young male elephant = 85.
Number of inches tall a young female elephant = 57.
Number of inches tall  if a young female elephant grows = 102.
Difference:
Number of inches tall  if a young female elephant grows – Number of inches tall a young female elephant
= 102 – 57
= 45.
Number of inches tall a young male elephant grows = Number of inches tall a young male elephant + 45
= 85 + 45
= 130.

Question 2.
A male box turtle is 17 years old. A female box turtle is 28 years old. When the male is 33 years old, how old will the female be?
Answer:
Number of years old is a female box turtle later = 44.

Explanation:
Number of years old is a male box turtle = 17.
Number of years old is a female box turtle = 28.
Number of years old is a male box turtle later = 33.
Difference:
Number of years old is a male box turtle later – Number of years old is a male box turtle
= 33 – 17
= 16.
Number of years old is a female box turtle later = Number of years old is a male box turtle later + 11
= 28 + 16
= 44.

McGraw-Hill Math Grade 4 Answer Key Chapter 2 Lesson 6 Addition and Subtraction Patterns

Add or subtract
Add or subtract to complete each table
Question 1.

Answer:

Explanation:
y = 0
=> y + 5 = 0 + 5 = 5.
y = 1
=> y + 5 = 1 + 5 = 6.
y = 2
=> y + 5 = 2 + 5 = 7.
y = 3
=> y + 5 = 3 + 5 = 8.

Question 2.

Answer:

Explanation:
x = 0
=> x + 12 = 0 + 12 = 12.
x = 12
=> x + 12 = 12 + 12 = 24.
x = 24
=> x + 12 = 24 + 12 = 36.
x = 36
=> x + 12 = 36 + 12 = 48.
x = 48
=> x + 12 = 48 + 12 = 60.
x = 60
=> x + 12 = 60 + 12 = 72.

Question 3.

Answer:

Explanation:
a = 30
=> a – 3 = 30 – 3 = 27.
a = 27
=> a – 3 = 27 – 3 = 24.
a = 24
=> a – 3 = 24 – 3 = 21.
a = 21
=> a – 3 = 21 – 3 = 18.
a = 18
=> a – 3 = 18 – 3 = 15.
a = 15
=> a – 3 = 15 – 3 = 12.
