Answer:
3/4 - 5/12 = 4/12 - 5/12 = -1/12
Step-by-step explanation:
Moby's addition and subtracting problem is as follows: Let us break the problem into solvable parts.
3/4 - 5/12
we will find the common factor of the denominator which are 4 and 12. The common factor is 12. We divide 12 by both denominator and multiply by the numerator .
3/4-5/12 = (9 - 5)/12 = 4/12 . This is his first error . 3/4 - 5/12 is equal to 4/12 not 3/12.
Now let us go to the second part which is the answer minus 5/12
4/12 - 5/12 = (4 - 5)/12 = -1/12
The final answer should be -1/12. This is another error that has been detected.
The correct answer combination should be as follows.
3/4 - 5/12 = 4/12 - 5/12 = -1/12
Answer:
Step-by-step explanation:
The number of miles that he ran last week is m.
His goal this week was to run one mile more than twice the miles he ran last week. This means that his goal this week is
m + 2m = 3m
If he tripled his goal, it means that the number of miles that he ran this week would be
3 × 3m = 9m
An expression in simplest form to show how many more miles he ran this week compared to last week would be
9m - m = 8m

Answer: D) $16.77</h3>
=====================================================
Explanation:
The meter goes from 9854 to 0023. You can think of 0023 as 10023 (even though the meter only has 4 digits, so it rolls over to start over again).
So,
10023 - 9854 = 169
This means 169 kw hours of electricity are used for the month of December.
The first 100 kw hours costs $4.35
There are 169-100 = 69 kw hours left, and they cost $0.18 each, so we add on 69*0.18 = 12.42 getting 4.35 + 12.42 = 16.77
Answer:
total would be $9.05
Step-by-step explanation:
$0.55 + $8.50
