<span>-3(2n+1)+7=-5
Multiply the number outside of the parenthesis with the numbers inside the parenthesis
-6n-3+7= -5
Subtract 7 from both sides
-6n-3=-12
Add 3 to both sides
-6n=-9
Divide -6 on both sides
Final Answer: n=1.5</span>
Those are equivalent take 100 times 1/4 it’s the same as dividing 4 :)
Answer:
(-8) + (-8) + (-8) + (-8)
Step-by-step explanation:
Since Yan is descending ; we represent his movement as being negative.
Number of rungs descended before stopping = 4
Number of stops = 8
Given that no extra steps was taken ;
Number of ladder rungs descended :
4 rungs per stop for 8 stops
- 4 * 8 = - 32 rungs
Another way to write the product :
Number of stops added in number of rungs descended :
(-8) + (-8) + (-8) + (-8)

4 = x
