Answer:
21.10 minutes
Step-by-step explanation:
6.75+7.1+7.25=21.10
Isolate the x. Do the opposite of PEMDAS. First, add 30 to both sides
-6 (+30) > - 30 (+30) - 4x
24 > -4x
Isolate the x. Divide -4 from both sides. Note that when dividing a negative, you must flip the sign.
24/-4 > -4x/-4
24/-4 > x
-6 < x
-6 < x is your answer
hope this helps
