When a certain number, m is divided by 5 and added to 8, the result is...
As per question,m is divided by 5 and add to 8 gives 8+m/5.
And is equal to 3m subtracted from 4 i.e. equal to 4−3m.
Then 4−3m=8+ m/5
⇒20−15m=40+m
⇒20−40=m+15m
⇒−20=16m
⇒m= −5/4

When a certain number, m is divided by 5 and added to 8, the result is...
The equation can be written as:
(m/5) + 8 = 4 - 3m
Multiplying both sides of the equation by 5 to eliminate the fraction:
m + 40 = 20 - 15m
Combining like terms:
16m = -20
Dividing both sides by 16:
m = -20/16
Simplifying:
m = -5/4
So the value of m is -5/4 or -1.25.
None of the answer choices provided match the value of m, so the correct answer is not given.
