6 small dolls + 5 large dolls = $65<em> ------------------ (1) </em>
5 small dolls + 4 large dolls = $53 <em>------------------ (2)</em>

<em>(1) x 5 : </em>30 small dolls + 25 large dolls = $325<span> <em>------------------ (1a)</em></span><em> </em>
<em>(2) x 6 : </em>30 small dolls + 24 large dolls = $318<em> ------------------ (2a)</em>

<em>(1a) - (2a) :</em> 1 large doll = $7

<em>Substitute 1 large doll = $7 into (1):</em>

6 small dolls + 5(7)  = $65
6 small dolls + 35  = $65
6 small dolls = $65 - $35
6 small dolls = $30
1 small doll  = $5

At a 3​-mile ​cross-country race, an athlete runs 2 miles at 6 mph and 1 mile at 12 mph. What is the​ athlete's average​ speed?
Tom [10]

Answer: the average speed is 7.5 mph or at least im pretty sure

Step-by-step explanation:

This is because if you make the 2 miles at 6 mph to 1 mile at 3 mph then you get 1 mile at 3mph and 1 mile at 12 mph. now that you have the unit rates of these you can add them. 1 + 1 = 2 miles and 3 + 12 = 15 mph now divide this by two and you get 7.5 mph per mile.

I hope this helped, if it did could you give me a good rating? lol
