With the decimal points, the first digit after the decimal starts out as tenths, and numbers above 5 are rounded up, so keeping those 2 facts in mind the answer would be
11.36
Answer:
3. No errors were made. The problem was worked correctly.
Step-by-step explanation:
2(10x + 3) − x = 44
Distribute
20x +6 -x =44
Combine like terms
19x +6 = 44
Subtract 6 from each side
19x =38
Divide by 19
19x/19 =38/19
x =2
Answer:
T = a + (n-1)d
Step-by-step explanation:
The arithmetic progression formula could be used to represent the series
T = a + (n-1)d
Where a = number of miles before increase
d = intended additional number of miles each day
n= number of days
Hence on the 2nd day, number of miles to be covered by Jeff will be
T = a + (2-1)d = a + d
The answers are as follows:
1-D
2-B
3-C
4-A
