Answer: 1) is 20
2) is 75 minutes
3) is estimated 63
Step-by-step explanation:
1) 200×90=18000÷100=180 and 200-180=20
2) 45÷12=3.75 which is the unit rate of minutes per question and 3.75×20=75 minutes
3) to long to explain and I don't know number 4
the correct answer would be -24x because 9+12 is 21 and 21 - 45 would be -24
Answer:
n = 2/3
Step-by-step explanation:
3n - 22 = -20
Add 22 to both sides
-20 + 22 = 2
3n = 2
Divide both sides by 3
2 / 3 = 2/3
n = 2/3
Let me know if I've done something wrong :)
