Let the lesser number be x and y the greater. Then
x + 65 = 4y , Also
y - x = 2
Adding:-
y + 65 = 4y + 2
63 = 3y
y = 21
and
x = 21-2 = 19
Answer the 2 odd numbers are 19 and 21.
In the given equation, as the value of <em>y</em> increase, the value of <em>x</em> also
increases.
- Yes, 4·y = 16·x is a direct variation
Reasons:
A direct variation is a relationship that exists between two variables. It is
also known as a direct proportion which can be expressed as; y = k·x
Where <em>k</em> is a number
The given equation is 4·y = 16·x
Dividing both sides by 4 gives;
Which gives;
y = 4·x
Comparing the above equation with the equation for a direct variation gives;
y = 4·x
y = k·x
Therefore;
k = 4
The equation, y = 4·x, and therefore, the equation from which it is derived, 4·y = 16·x, is a direct variation.

Step-by-step explanation:
Answer:
Since Her goal is to earn $ 300 , but now she is earning only $270 ,Hence Celia will not achieve her goal .
Step-by-step explanation:
Given as :
The cost of each calendar = $ 9
The number of calendar sold to the family = 16
The number of calendar sold to the neighborhood = 14
So, Total number of calendar sold by Celia = The number of calendar sold to the family + The number of calendar sold to the neighborhood
i.e Total number of calendar sold by Celia = 16 + 14 = 30
∵ The cost of each calendar = $ 9
∴ The cost of 30 calendar = $ 9 × 30 = $ 270
Since Her goal is to earn $ 300 , but now she is earning only $270 ,Hence Celia will not achieve her goal . Answer
He needs to earn ; 77.99-20= 57.99 dollars
so in one week there are 2 weekends; so he earns 6×3×2 = 36 dollars
so no of week = 57.99÷ 36= 1.6 weeks
so weeks are in natural no thus it will take him 2 weeks !!
