Answer: Required expression= 412-34
Current quiz grade average = 378
Step-by-step explanation:
Given: The average points on daily quizzes = 412
The average decreases by 34 points. (Near the end of the quarter)
Current quiz average = (Average points on daily quizzes) - (Average decreases)
i.e. Current quiz average =412-34 [ i.e. Required expression= 412-34]
i.e. Current quiz average =378
Hence, his current quiz grade average = 378
Answer:
2 hours and 44 minutes.
Step-by-step explanation:
In 1 hour, Mary can clean 1/6 of the apartment, while her roommate cleans 1/5 of the apartment. To represent both of them working together, you add both fractions : 1/5 + 1/6 = 11/30. To find out how long it would take, you divide 1 by 11/30. 1/1 ÷ 11/30 = 1/1 × 30/11 = 30/11 hours. Make the fraction a mixed number : 30/11 = 2 8/11. 8/11 ≈ 0.727. Multiply 0.727 with 60 minutes : 0.727 × 60 = 43.62 minutes. Round 43.62 : 44 minutes. Result : 2 hours and 44 minutes.
Answer:
v=3
Step-by-step explanation:
141=-v-8(-8v+6)
distribute -8 into the parentheses
141=-v+ 64v-48
simplify by putting v's together
141=63v-48
add 48 to both sides to get x by itself
189=63v
divide both sides to isolate x
v=3
