I'm going to add a few missing terms (that fit the pattern that you gave):

x  =  1      2      3     4     5     6     7

y  =  7    11    15    19    23   27    31

Notice that as each x-term increases by 1, the corresponding y-term increases by 4.

This means that this is a linear equation with slope = 4.

y  =  mx + b                   (with m = 4)

y  =  4x + b

Now, substitute any (x,y) pair into this equation.  I'm going to use (5,23), but I could have used any pair.

23  =  4(5) + b

23  =  20 + b

3  =  b

This means that a possible equation is:  y  =  4x + 3.

Let Alicia's age = A

Amy's age =2A + 8, so we have:

A + [2A + 8] < 32  

3A + 8 < 32    subtract 8 from both sides

3A < 32 - 8

3A < 24           divide both sides by 3

A < 24 / 3

A < 8   Alicia is less than 8 years old.

Let the number = N. Then we have:

7[N - 9] = 4

7N - 63 = 4 

7N =4 + 63

7N = 67 divide both sides by 7

N = 67 / 7

N = 9 4/7

We would all roast and die of oxygen lost instantly on earth but if it's the whole universe, then all black holes would either disappear and swallow us whole in seconds. Either way it would not end well in any way in under 10 seconds.

3 seconds.

this is very wierd.... and confusing

You're welcome, Guest. 

thank you

\(41=12d-7\)

+ 7 =           + 7

\(48=12d\)

\(\frac{48}{12}=\frac{12d}{12}\)

\(4=d\)

Actually, according to a Wall Street Journal article, New York State wildlife expert Richard Thomas reasoned that if a woodchuck could chuck wood, he would chuck an amount equal to 700 pounds.

 1=0.05(q+2)+0.25q

1 =0.05q +0.1 +0.25q   isolate q to one side

1 - 0.1 =0.05q + 0.25q

0.9 =0.3q   divide both sides by 0.3

q = 0.9 / 0.3

q = 3

Let the number of quarters =Q

Number of nickels =Q + 2, But:

0.25Q + 0.05[Q + 2] =1

0.25Q + 0.05Q + 0.1 =1

0.3Q = 0.9 divide both sides by 0.3

Q =0.9 / 0.3

Q = 3 - Number of quarters.

3 + 2 = 5 Number of nickels, so that:

[3 x 0.25] + [5 x 0.05] =$1
