Lets x = Mary's age
Emily is there years older than twice her sister Mary's age = 2x + 3
Sum of both is less than 30:
x + 2x + 3 < 30
Solve for x
3x + 3 < 30
3x < 27
x < 9
Mary's age = 9
Inequality represents Mary's possible age:
0 < x < 9
Answer is the second one
0 < x < 9
<span>To subtract 3 3/8 from 5 1/2,
by turning into fractions
</span><span>[(5x2)+1]/2 = 11/2
</span><span>[(3x8)+3]/8 = 27/8
</span><span> 11/2 - 27/8
</span>To subtract fractions, your denominator needs to have the same number. so multiply it by 4
44/8 - 27/8 = (44-27)/8 = 17/8.
17 / 8 pounds or 2 and 1/8 because 17 / 8 = 2 remainder 1.
<span>In terms of weight that is 2.125 pounds.</span>
