Answer:
4:7
Step-by-step explanation:
18+24=total number of fish=42
silver fish amount= 24
therefore, ratio is 24:42=12:21=4:7
8n+3=5
8n=2
N=.25
The number is .25 or 1/4
Answer:
15
Step-by-step explanation:
So, between 14 and 15 would be where 14 5/6 is at. But, 14 3/6 would be directly in the middle of the two. Since 14 5/6 is greater than 14 3/6, it would round up to 15 instead of rounding down to 14.
the property of a rectangle two opposite sides are the same. meaning the length that is X must have the same length on the other side right. Same thing as the side 2 4/5. so there are 2 of that same number. you're basically multiplying it by 2
expression
2x + 2(2 4/5) = P
if you don't understand that it's basically like this
x + x + 2 4/5 + 2 4/5 = P (it's the same as the above expression)
P = perimeter of rectangle
