eads does Naomi have?
2 answers:
Let w = white beads. Solve for w and then find the number of red beads.
<span>w + 6w + 1 = 50 </span>
<span>7w = 50 - 1 </span>
<span>7w = 49 </span>
<span>w = 49 / 7 </span>
<span>w = 7 </span>
<span>She has 7 white beads. </span>
<span>7 * 6 = 42 red beads </span>
<span>Check: </span>
<span>7 + 1 + 42 = 50 So... the real answer is 42...
