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.
Answer: a = _____

    3a = 50-5
    3a = 45
    a = 15

    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
