Ratio and proportion
real:shadow
so the person is 1.8m but the shadow is 4m
so
real:shadow=1.8:4
so
1.8:4=?:14
1.8/4=?/14
times both sides by 14
25.2/4=?
6.3=?
the tree is 6.3 m tall
Answer:
3 5/6 = 3 10/12
2 1/3= 2 4/12
3-2=1
10/12-4/12= 6/12=1/2
so Kyle read 1 1/2 more books then Jan

The pairs of goldfish Tasha can buy for $20 are

Step-by-step explanation:
To find the how many type of goldfish that Tasha can buy for $20 is the set of positive ordered pairs.
Let x denote the number of fancy goldfish.
Let y denote the number of common goldfish.
To find how much goldfish can Tasha buy for $20 is to substitute the value for x in the equation 
Now, substituting
in
, we get,

The ordered pair is 
Similarly, substituting
,

For

Thus, the pairs of goldfish Tasha can buy for $20 are 

P = 3x + 2y
There is an accompanying graph in this problem. In the graph, there are 4 points to consider. I'll just assign letters on each point.
Point O is found in x = 0 ; y = 0 or (0,0)
Point A is found in x = 8 ; y = 0 or (8,0)
Point B is found in x = 6 ; y = 5 or (6,5)
Point C is found in x = 0 ; y = 8 or (0,8)
We will substitute x and y in the equation by its values per point.
Point A = 3(8) + 2(0) = 24 + 0 = 24
Point B = 3(6) + 2(5) = 18 + 10 = 28
Point C = 3(0) + 2(8) = 0 + 16 = 16
The maximum value of the function P = 3x+2y is 28 and its minimum value is 16.
