Asked by Kiki
In the Apollo spacecraft, the service module weighed 3000 lbs less than 5 times the weight of the command module.The lunar module weighed 1000 lbs less than 3 times the weight of the command module.If the total weight of the three modules was 95000 lbs, how much did each weigh?I need help finishing the problem.
s=3000-5c l=1000-3c l+c+s=95000
1,000-3c+c+3000-5c=95000
1,000+-7=95,000
s=3000-5c l=1000-3c l+c+s=95000
1,000-3c+c+3000-5c=95000
1,000+-7=95,000

Why use all those variables?
let the weight of the command module be x
now just translate the given English into Math
"the service module weighed 3000 lbs less than 5 times the weight of the command module"
---> sm = 5x-3000
"The lunar module weighed 1000 lbs less than 3 times the weight of the command module"
sm = 3x-1000
"If the total weight of the three modules was 95000 lbs"
---> x + 5x-3000 + 3x-1000 = 95000
notice only one variable,
solve for x
sub back into my definitions.
