Leah liked to balance objects she found around the house using the science kit she got for Christmas. She found that 3 identical apples and a 5-gram weight exactly balanced a 50-gram weight. Leah said she could tell how much each apple weighed by solving the equation 3a+5=50. Prove Leah was correct by finding the weight of 1 apple.

• Math -

3a = 50-5
3a = 45
a = 15
(if they really are identical, unlikely)

• Math -

3a+5=50

3a = 50 - 5
3a = 45
a = ?

• Math -

3a + 5 = 50
3a = 50 -5
3a = 45

• Math -

3a + 5 = 50
3a = 50 - 5
3a = 45
a = 15
3(15) = 45
