Answer:
![P = \frac{2}{3} [J(y)] - 2](https://tex.z-dn.net/?f=P%20%3D%20%5Cfrac%7B2%7D%7B3%7D%20%5BJ%28y%29%5D%20-%202)
Step-by-step explanation:
If Jojo completes P number of paintings working w weeks then the relation between P and w is given by 
. ........ (1)
Again, the function J(y) represents how many weeks per year she spends painting.
So, w = J(y). ...... (2)
Therefore, the composite function which represent how many paintings Jojo completes in a year, is given by
(Answer)
Answer:
I. First number, a = 40.
II. Second number, b = 50.
III. Third number, c = 120.
Step-by-step explanation:
Let the three numbers be a, b and c respectively.
Given the following data;
Translating the word problem into an algebraic equation, we have;
a + b + c = 210
b = a + 10
c = 3a
Substituting the value of b and c into the equation, we have;
a + a + 10 + 3a = 210
5a + 10 = 210
5a = 210 - 10
5a = 200
a = 200/5
<em>a = 40</em>
To find the value of b;
b = a + 10
b = 40 + 10
<em>b = 50</em>
To find c
c = 3a
c = 3*40
<em>c = 120</em>
Answer:
4/9
