Answer:
13 2/9
Step-by-step explanation:
Cows eats=5 3/5 Hays everyday
Horses eats=1 5/6 as much as the cow
=1 5/6 of what the cow eat+5 3/5
=1 5/6 × 5 3/5 + 5 3/5
=11/6×28/6+28/6
= 308/36+28/6
=308+168/36
=476/36
=13 8/36
=13 2/9
A formula is recursive if it expresses the term
in terms of the previous one(s) 
In this case, every term is 7 more than the previous one, so the formula for
will only involve
:

In fact, this formula is simply saying: for every index
, the term with that index is 7 more than the term before.
Also, we have to specify the starting point (otherwise we would go backwards indefinitely), so the complete recursive formula is

which means: start with 2 and generate every other term by adding 7 to the previous one.
Answer:
12 is the y intercept and -3x is the slope
Step-by-step explanation:
Answer:
20 degrees.
Step-by-step explanation:
The 3 angles of a triangle add up to 180 degrees.
Therefore the third angle in this triangle
= 180 - (120 + 40)
= 180 - 160
= 20 degrees.
