Answer:
The students spent 135 minutes in lecture and 115 minutes in a lab.
Step-by-step explanation:
Let x and y be the respective amount of time students spent in lecture and lab.
x-20=y --- eqn 1
x+y=250 --- eqn 2
From eqn 1, x=y+20 --- eqn 3
Sub eqn 3 into eqn 2:
y+20+y=250
2y=230
y=115
Sub y=115 into eqn 3:
x=115+20
=135
∴x=135, y=115
It should be x=11. could someone fact check me?
What do you mean by that because I freak my don’t understand you alquestio
