So i have a problem and it's about inequality, and it required me to answer it in a complete sentence, little help please :)
Problem: Glenda has a $40 gift certificate to a cafe that sells her favorite tuna sandwich for $3.75 after tax. What are the possible number of tuna sandwiches that Glenda can buy with her gift certificate?! And it even said to define a variable, write an inequality then solve. Anyone help me? Thanks :)

Best ResponseYou've already chosen the best response.0do you know how to solve for x? as in 3x=15

Best ResponseYou've already chosen the best response.0ok think of the equal sign as line, and you want to balance each side out

Best ResponseYou've already chosen the best response.0if you have 3 times some number = 15 then 3 times what would give you 15?

Best ResponseYou've already chosen the best response.0x is just a number that we don't know what it is yet but we knw that 3*(this number) is 15

Jusaquikie

Best ResponseYou've already chosen the best response.0now if we didn't know that 3*5 is 15 we could take the 3 to the other side and then all we have on the 1 side is x=

Best ResponseYou've already chosen the best response.0that would be right it it were 3+x=15 but if it's 3*x we have to divide 3

Best ResponseYou've already chosen the best response.0ohh i was right nvm again :P

Best ResponseYou've already chosen the best response.0think of the equal sign like the opposite side, so if you 3*5=15 then 3=15/5

Best ResponseYou've already chosen the best response.0if it's multiplied on 1 side then to move it you devide the other side by what your moving, if it's just + or  then you change the sign and add or subtract from the other side

Jameshappy

Best ResponseYou've already chosen the best response.0so 3x=15 then its gonna be 15+3=x?

Best ResponseYou've already chosen the best response.0can you put it in a simple way ?

Best ResponseYou've already chosen the best response.0no if x is next to a number without a + or minus between that means x multiplied by the number

Best ResponseYou've already chosen the best response.0ok gotcha i know that but how to make it balance on either sides?

Jusaquikie

Best ResponseYou've already chosen the best response.0just like x/3 is x divided by 3

Jusaquikie

Best ResponseYou've already chosen the best response.0so if you had \[\frac{ x }{ 3 }=5\] that would mean that you would need to multiply both sides by 3 so you would get \[\frac{ 3x }{ 3 }=5*3\] the 3 and 3 cancle out and your left with x=3*5 or 15

Best ResponseYou've already chosen the best response.0yes i think your starting to understand a bit

Jusaquikie

Best ResponseYou've already chosen the best response.0they are still equal if you do the same thing to both sides so to move 3+x=15 we would subtract 3 from both sides and we get x+12 if we have 3x=15 we have to divide both sides by 3 so we get x=15/3 or 5 if we have x/3= 5 we multiply both sides by 3 and get x= 3*5 or 15

Best ResponseYou've already chosen the best response.0OH i get it so back to the problem 3x=15 would be x=5?

Best ResponseYou've already chosen the best response.0< and > work the same way if 3+2>4 then 3>42

Best ResponseYou've already chosen the best response.0yes that is correct lets' try this one to be sure you understand \[4x=20\] what is x?

Best ResponseYou've already chosen the best response.0So what about this prbolem? : 2/3 > 1/2  d/6 / < mean " over". Like 2 over 3, 1 over 2 and d over 6

Best ResponseYou've already chosen the best response.0ok treat the > just like you would = what would you do first?

Jusaquikie

Best ResponseYou've already chosen the best response.0you are trying to get d by itself

Jusaquikie

Best ResponseYou've already chosen the best response.0no we want to save that for last wet's get the addition/subtraction out of the way first, \[\frac{ 2 }{3 }>\frac{ 1 }{ 2 }\frac{ d }{ 6 }\] so if we move 1/2 over it becomes 1/2

Jusaquikie

Best ResponseYou've already chosen the best response.0so\[\frac{ 2 }{ 3 }\frac{ 1 }{ 2 }>\frac{ d }{ 6 }\] now how do we subtract fractions?

Best ResponseYou've already chosen the best response.0don't worry about the d/6 right now one piece at a time, math is all in baby steps, when we try to skip stuff we make mistakes so think of it as doing what we know how to make it simpler and right now we can make it simple by subtracting our fractions 2/31/2

Best ResponseYou've already chosen the best response.0yeah some day you can help out a seventh grader lol and it's all be good

Best ResponseYou've already chosen the best response.0haha thanks :) OK back to the prob. so 2/3  1/2 gonna be 1?

Jusaquikie

Best ResponseYou've already chosen the best response.0so to subtract the denominator has to be the same so we make them the same by finding something in common or cross multiplying so \[\frac{ 2*2 }{ 3*2 }  \frac{ 1*3 }{ 2*3 } = \frac{ 4 }{ 6 }\frac{ 3 }{6 }\]

Jameshappy

Best ResponseYou've already chosen the best response.0oh yeah i forgot im not that good at math :P or sp its gonna be 1/6 ?

Jusaquikie

Best ResponseYou've already chosen the best response.0now we have \[\frac{ 1 }{ 6 }>\frac{ d }{6 }\] what would happen if we multiplied both sides by 6?

Jameshappy

Best ResponseYou've already chosen the best response.0uhm it still gonna be the same number. But since it lready 6 so i dont think we have to

Jameshappy

Best ResponseYou've already chosen the best response.0oh so the answer gonna 6?

Best ResponseYou've already chosen the best response.0no, if you have a slice of pizza that is 1/6 of the pizza and then you multiply that by 6 what do you have?

Best ResponseYou've already chosen the best response.0the bottom number means that your top number is cut in to that many pieces so 1/6 of a pizza means that you have 6 pieces to make a whole pizza

Jameshappy

Best ResponseYou've already chosen the best response.0so the answer is 6/6?
