Kyle has 147 total beads. He has the same amount of beads in 5 different colors. He also has 92 clear beads. Which of these equations can be solved to determine the unknown number of each color of bead? Choose all that apply.
A. (147 - 92) = b + 5
B. 92 = 147 - (b × 5)
C. (147 - 92) ÷ 5 = b
D. 147 = (b × 5) + 92
C. (147 - 92) ÷ 5 = b
D. 147 = (b × 5) + 92
What is the solution? Explain how to use order of operations to solve.
10 × (8 - 2) + 24 ÷ 4
66; Sample answer: According to the order of
operations we solve within the parentheses first:
10 × (8 - 2) + 24 ÷ 4 = 10 × 6 + 24 ÷ 4. Then
multiply and divide from left to right:
60 + 24 ÷ 4 = 60 + 6. Then add and subtract
from left to right: 60 + 6 = 66.
