Answer:
70
Step-by-step explanation:
(Not the most streamlined way but.)
Knowing that if he had 5 tests, and a mark of 85, we can determine the total average grade Bill received. 85*5=425
Then subtract the known grades
425-(90+85+100+80)=x
425-(355)=x
70=x
Bill would have scored 70 on that 5th test
Answer:
6/23
Step-by-step explanation:
spinner was spun 23 times, 5 times it landed on 5 and once on 7, so:
P(5 or 7) = 5/23 + 1/23 which is 6/23
Answer: 9 textbooks
Step-by-step explanation:
25 x 120.00 = 3,000
4,000 - 3,000 = 1,000
9 x 105.00 = 945
1,000 - 945 = 55
The teacher can only buy 9 textbooks since she/he doesn't have enough money to get anymore.
