Answer:
C
Step-by-step explanation:
1.75n = 7 ( to isolate n divide both sides by 1.75 )
n = = 4
c.) Divide by 1.75
Given equation:
⇒ 1.75n = 7
Here the coefficient of n which is 1.75 needs to be removed. There is only one way of doing that - by dividing both sides by 1.75.
When done so:
⇒ 1.75n/1.75 = 7/1.75
⇒ n = 4
it is the very middle 6
