Marisa had rounded 3.48 to 4 and times it to 7.33 which she rounded to 8

Answer:
Peyton: 6 years old
Matt: 24 years old
Justin: 9 years old
Step-by-step explanation:
P= Peyton M= Matt J= Justin
P=J-3
M=4P
J+P+M=39
4J-12=M 4J-12=39-J-P
5J-51=-P P=J-3
5J-51=-J+3 J=9
P=9-3 P=6
M=4(6) M=24
<em>Let </em><em>the </em><em>two </em><em>numbers </em><em>be </em><em>3x </em><em>and </em><em>4x</em>
<em>sum </em><em>=</em><em>3x </em><em>+</em><em> </em><em>4x </em><em>=</em><em> </em><em>7x</em>
<em>7x </em><em>=</em><em> </em><em>133</em>
<em>x=</em><em> </em><em>19</em>
<em>the </em><em>numbers </em><em>are </em><em>:</em>
