Answer:
here's the answer to your question
$24/5 = $4.8 x 3 = $14.4
$24/6 = $4 x 1 = $4
$14.4 + $4 = $18.4
$24 - $18.4 = $5.6
Divide 45 by three because it is 3:4 of the cost then mutiply it by four so e entire cost would be 60.
Ok, I'll make it simple for you: Keep Change Change. For all subtraction problems (and only subtraction, no addition), all you have to do is keep the first number, then change the sign from a minus to a plus, and then change the last number to the opposite. For example:
7 - (-3)
7 + 3=10
-4 - 10
-4 + -10= -14
For addition, if both numbers are negative, you just add them together. For example:
-21 + (-13)= -34
In this case you switch the sign and the number's sign also:
7 + (-18)
7 - 18 = -11

Let the two ages be j and m, respectively. Then j+m>32.
Solving for Mary's age, we get m > 32 - j. Because j = m + 2, m > 32 - (m+2).
Continue solving for m: Adding m to both sides of this inequality results in
2m > 32 - 2. Then 2m > 30, and m > 15. Mary's age is greater than 15.
