A will represent Anna. k will represent Kylie.
7a+7k=231
a=9+k
Substitute for a
7(9+k)+7k=231
63+7k+7k=231
14k=168
k=12
Then plug in the k value
a=9+12
a=21
Final answer: Anna=21 mph, Kylie= 12 mph
Answer:
c
Step-by-step explanation:
it would be c. because there are 4 friends and there and 5 burritos so each one gets 1 and the last one slips to 4 pieces.
If you mean <em>x</em> = 0.666…, then
10<em>x</em> = 6.666…
10<em>x</em> - <em>x</em> = 6.666… - 0.666…
9<em>x</em> = 6
<em>x</em> = 6/9 = 2/3
If you mean <em>x</em> = 0.060606…, then
100<em>x</em> = 6.060606…
100<em>x</em> - <em>x</em> = 6.060606… - 0.060606…
99<em>x</em> = 6
<em>x</em> = 6/99 = 2/33
