I have to fill in the missing values in this invisible chart The cation is Sn+2, the Anion is SiO3^-2. I think the compound is SnSiO3, and the name is silicite. Is this right? The cation is Al3+, the anion is S^-2. I guessed the compound was Al2S3, and th...

Imagine you are in the market for a new home and are interested in a new housing community under construction in a different city. The sales representative informs you that there are 56 houses for sale two floor plans still available. Use x to represent f...

There are 38 houses in a new community available with two floor plans. Floor plan x sells for $175,000 and Floor plan y sells for $200,000. The total worth of all available homes are $7,200,000. Write an equation that illustrates this situation. Part A: x...

the grid is x y (x,y) -1 -2 -4 2 8 this is to the previous asked question from me.

the answer is m=-11 over 2. Hope this helps you.

thanks I thought the same. Now the second question is The sales representative later indicates that there are three times as many homes available with the second floor plan than the first. Write an equation that illustrates this situation. Use the same va...

An inequality shows two statements that are true only if one statement differs from the other by being greater than, or equal to the other. ex: x+1>3 changing > to = then x will be x=2 now substitute the > gives you x>2. Inequalities have multiple solutio...

Not quite understanding since the y is only now 3 times more than x so shouldn't the variable stay the same as in the first part when making the equation?

Now using the equations from Part A and Part B. use substitution to determine how many of each type of floor plan is available. Describe the steps you used to solve the problem

x+y=36

thank you. Now using Part A and B what is the intercepts of part A and what are the intercepts of part b? Where would the lines intersect if you solved the system by graphing?

my problem with the first one is how did you get a 4 when it is 3 times as many? would that 4 be a three instead and does that change the outcome of the solution?

Thank you once again. I was getting the same answers but I was wondering if I was wrong. Seems you made it correct in thought for me. Here is another one: The sales representative here tells you they also have two floor plans available at another communit...

I thought that maybe it would be. $175,000x+$200,000y=$7,200,000 Would this be correct?

can you explain how to do the elimination part of 2c?
