Answer:
We solve the equations g + e = 117 and e / g = 2 / 7; where g = number of gas mowers and e = number of electric mowers;
So, g = 117 - e and 2g = 7e;
Then, 2( 117 - e ) = 7e;
234 - 2e = 7e;
234 = 9e;
e = 234 ÷ 9;
e = 26;
g = 117 - 26;
g = 91;
Step-by-step explanation:
2.74 - (-19.4) = 22.14, so the freezer is 22.14°c colder. I hope that helps!
