Answer:
The best option is c
Step-by-step explanation:
The same textbooks contains a total of 848 pages . Which represent the total number of pages , y , of any number of the same textbooks , x.
The number of same text book = x
Each of this textbook contains a total of 848 pages .
The total number of pages can be computed as
y = 848x
for 4 same text book
y = 848 × 4 = 3392 pages
for 3 same text book
y = 848 × 3= 2544 pages
for 7 same text book
y = 848 × 7 = 5936 pages
for 8 same text book
y = 848 × 8 = 6784 pages
for 11 same text book
y = 848 × 11 = 9328 pages
Answer:
1. 4(10+8) 40+32=72
2. 5(15*3-2) 5(45-2) 225-10=215
Step-by-step explanation:
Answer: 2,000 ÷ 50
Step-by-step explanation:
From the question, we are informed that John needs to write 2,146 online math questions in 45 weeks and that he is estimating how many questions he should write each week to meet the deadline.
The compatible numbers that provide a better estimate for the number of question he should write each week, is 2,000 ÷ 50. This is because rounding up of 2146 to the nearest thousand gives 2000. The number beside the thousand place is 2 and sinces it's not up to 5, the number becomes 2000. Likewise 45 to the nearest ten gives 50 since the number beside the ten is 5, therefore 1 will be added to 4 which becomes 5 and the number in the unit place is changed to 0, this makes the number become 50.
Therefore, the answer is 2000 ÷ 50.
