Homework - jumps

Sasha jumped 141 cm Peter 4 cm more than George.
Jirka 6 cm less than Misha. Misha 7 cm less than Philip, and Philip is half as much as Sasha and Petr together. How far does each jump?

Final Answer:

S =  141 cm
P =  123 cm
J =  119 cm
M =  125 cm
F =  132 cm

Step-by-step explanation:

S=141=141 cm
P = 4+J  J = M−6  M = F − 7  F = (S+P)/2  F = (S+P)/2 = (4+J+S)/2 = (4+M−6+S)/2 = (4+F−7−6+S)/2 F = (4+F−7−6+S)/2 2F = 4+F−7−6+S F=4−7−6+S=4−7−6+141=132 cm M=F−7=132−7=125 cm  J=M−6=125−6=119 cm  P=4+J=4+119=123 cm
