Well, there are 1760 yards in a mile
so then 1760 times 12 = 21120
The library is 21,120 yards from the post office
:D hope i helped
-8x - y = 4
-y = 8x + 4
y = -8x - 4....slope = -8, y int = -4
-8x - y = 9
-y = 8x + 9
y = -8x - 9...slope = -8, y int = -9
same slopes, different y int....means parallel lines...no solution <==
** just so u know..
same slopes, same y int = coincident lines = infinite solutions
different slopes, different y int = one solution
Answer:
B. 229
Step-by-step explanation:
I solved it by multiplying the 4.02 and 29.92. Then, added the numbers together and rounding the solution to the nearest whole number.
You set up a proportion so: 12/x and 40/100
Cross multiply so 12 times 100 = 1200
and 40 times x = 40x
1200 divided by 40 = 30 minutes total
You know that he already know he spent 12 minutes doing it so
30 - 12 = 18 more minutes
