Thank you!That made sense :)

My choices are : 200 450 750 1,000 I calculated, if I am right, 200.

Yes that does make sense! I was wayyy off. Glad I asked. Thank you Ms. Sue.

I really need help with it.

Yeah so I was correct Ms. Sue? 1/2 ?

Thanks guys that makes sense now. And especially thank you because you explained it in detail not just giving me the answer so i can really understand. :)) You guys are awesome:) Hope I can ask another question later if needed.

oops! You are right it was suppose to be 3 7 sorry and big thanks!

hi Ms. Sue. It is not to solve but how I am suppose to write out to solve. the choices were; 11/21 = r 1,500 ***** this is the one I chose. 11/100 = r /1,500 21/100 = r/1,500

oops I mean 11/21 = r/1,500 I chose. :)

In a zoo, 21%of the animals are reptiles, 11% are birds. There are a total of 1,500 animals in the zoo. Which proportion can be solved for r, the number of reptiles in the zoo. Is this the correct proportion that I wrote to solve? 11/21 = r/1,500 I chose....

One more quick question? is 62/7 opposite is -62/7 ?

Ohh yeah of course because obviously I am not trying to figure out the birds. oops! Thanks!

yeah:)! thank you

Ok so will it look like this then? y = 30 + 80 y= 48 + 80 And the answer would be $18?

Yeah!!:))))) Thanks guys!

3.5 feet by 18 feet Is this right?

119 feet by 63 feet. because I had to get feet to inches right?

The choices are that one or 3 foot tall mail box is represented by an 18 inch tall drawing or the 29.5 foot wide play ground answer

Thank you!! Damon. I really appreciate you guys being here. I am writing this in my notes. Thank you again.

Ok so out of 5. And 5 x 225 times it landed on the red section. Thank you! Can you delete this question?

Ok I get it thanks. Each play he makes 75% of his passes. I don't do enough probability to know it well. It is a small very small quick section at school. And it is rushed through. :( I need your help on others if you don't mind?

Thank I am really trying really hard to understand. I got other ones I haven't posted here. I just ask for the ones I tried over and over again. Thank you.

I am writing what you wrote Damon in my math note book. Thanks.
