P=2(L+W)
L=2/3x+10
W=1/3x+5
P=2(2/3x+10+1/3x+5)
P=2(2/3x+1/3x+10+5)
P=2(3/3x+15)
P=2(x+15)
P=2x+30
Answer:
After 12.2 miles
Step-by-step explanation:
You can check this by graphing y = 0.85+16.75 and y = 0.40 + 22.25 and looking for the solution (the point where they intersect).
You can also use the elimination or substitution method.
Answer:
Start: Brown feather % is 97% Grey feather % is 3%
End: Brown feather % is 19% Grey feather % is 81%
Step-by-step explanation:
Start:
There is 700 total feather (679+21) so to get to 100(the denominator for percentages) you have to divide by 7
divide each number by 7(679/7 and 21/7)
and you get 97 and 3 which will be your percentages
End:
There is 740 total feather (140+600) so to get to 100(the denominator for percentages) you have to divide by 7.4
divide each number by 7.7(140/7.4 and 600/7.4)
and you get about 19(rounded) and about 81(rounded) which will be your percentages
Hope this helps!!!
Answer:
By these examples you are able to see that the square of an odd number is always 1 more than a multiple of 4.
Step-by-step explanation:
For examples,
Let's consider squares of 3, 11, 25, 37 and 131.

8 is a multiple of 4, and 9 is more than 8.

120 is a multiple of 4 and 121 is one more than it.

624 is a multiple of 4 and 625 is one more than it.

1368 is a multiple of 4 and 1369 is one more than 1368.

17160 is a multiple of 4.
