Huh? Is their a picture or anything else that goes with that question?
Answer =37.5 rows of two
Explanation= you can do 75 divid by 2 to get rows of two each of 75.
3.75 meters I would presume.
Explanation: since a single meter casts a shadow of 0.75 meters that means for each meter, 0.25 meters are missing. So I added 0.75 to three, because there was 3 meters and 3 time 0.25 was 0.75 .
So what they are saying is the sum of 2x +13=75
Therefore we can just solve for 2x, our unknown value.
2x+13=75 now subtract 13 and divide by 2 from both sides of equation to not change the equation
x+13-13=75-13
This leaves us with
x=(75-13)/2=31 therefore x=31 or our unknown value is 31.
I hope this helped. Any questions please just ask. Thank you.
