Question: 1. Bees have 6 legs. Spiders have 8 legs. Joshua saw a picture of spiders and bees and counted 36 legs altogether. How many bees did Joshua see in the picture? A) 2 B) 3 C) 4 D) 6 2. There are 2 types of starfish in a rock pool: 5 pointed ones and 6 pointed ones. Emily counted 49 points in total. How many starfish were in the rock pool altogether? I'm so stuck on these two questions.. I can only get one algebra equation for each.. for 1) 6x + 8y = 36 and 2) 6x + 5y = 49 but they have two unknowns so how do you solve them??? thank you so much, i really appreciate it xoxo

[Diophantine equations] 1. Let S = the number of spiders in the picture, and Let B = the number of bees in the picture. Then, there were 8S + 6B = 36 legs. So, B = 6 - 8S/6 Since 8S/6 must be a whole number, S = 3 B = 6 - (8)(3)/6 = 6 - 4 = 2 bees (A) ∎ SOLUTION 1 2) Possibilities for the number of points from five-pointed starfish are: F = {5, 10, 15, 20, 25, 30, 35, 40, 45} Possibilities for the number of points from six-pointed starfish are: S = {6, 12, 18, 24, 30, 36, 42, 48} The total number of points is the sum of one element in F and one element in S. Since the units digit of the sum is 9, and the units digits of all the elements in F are either 0 or 5, the element from S must have a units digit of either 9 or 4. The only element in S with a units digit of either 9 or 4 is 24. So the element from F must be 25, and there are: 25 / 5 + 24 / 6 = 5 + 4 = 9 starfish in the pool ∎ SOLUTION 2

Have you spoken to your doctor about perhaps you taking a unisom at night to knock you out so you can get some sleep? There are sleep aids that are approved for use during pregnancy and it may be enough to keep you asleep even if your legs don't agree. During the day you will just have to deal with it probably, but you are so close, your baby will be here in 2 months... you just gotta hang on a bit longer.

1) 6x + 8y = 36 => if x = 1,then 8y = 30[not possible] => if x = 2 ,then 8y = 24 =>y = 3[possible] =>A) = 2 is the right answer. 2) 6x + 5y = 49 => if x = 1,then 5y = 43[not possible] =>if x = 2 ,then 5y = 37[not possible] =>if x = 3 ,then 5y = 31[not possible] =>if x = 4 ,then 5y = 25 =>y = 5[possible] =>Total no. of fish = 4 + 5 = 9 is the right answer.

You try spinning a beautiful, strong, symmetrical web in one hour with just 2 legs. Or scaling up walls and catching a cockroach that is as big as you are and much heavier and struggling to get away. Or jumping from ambush position to catch a quick moving fly and succeeding. They use what they have very well. Eyes too - how many pairs do spiders have again? Wonderful creatures!　 Wow! Devon 1754! Great info! Yes, 8 eyes too! And you forgot to mention that in times of famine, when they can't catch food, they can live off their own silk! How amazing is that! Some of the huge ones, that don't spin webs, will eat cat food or dog food if it is available.

1. if he saw spiders and bees, the only possible answer for 36 legs is 2 bees, 6(2) + 8(3) = 36 2. I think you put the question wrong.
