Proportionality or variation is state of relationship or correlation between two variables It has two types: direct variation or proportion which states both variables are positively correlation. It is when both the variables increase or decrease together. On the contrary, indirect variation or proportion indicates negative relationship or correlation. Elaborately, the opposite of what happens to direct variation. One increases with the other variables, you got it, decreases.

2x-py=5 and 4x+5y+q=0.
Mademuasel [1]

Answer:

q = 1 and p = 3

Step-by-step explanation:

Since we are already given the value of x and y, then it will be easy to get what p and q is. What is needed to be done is just to insert the values of x and y in both equations

For equation 1

2x -py = 5

insert x = q and y = -1

2(q) -p(-1) = 5

2q + p = 5

for the second equation, we do same

4x + 5y + q = 0

insert x = q and y = -1

4(q) + 5(-1) + q = 0

4q -5 + q = 0

5q = 5

q = 5/5 = 1

Recall from above, 2q + p = 5

Insert q = 1, we have ;

2(1) + p = 5

2 + p = 5

p = 5-2

p = 3

jane loves animals. She has an equal number of beetles, birds and spiders as pets. Apart from human legs, there is a total of 27
kherson [118]

Answer:

16.875 spiders

Step-by-step explanation:

Given

Let

B = Beetles

C = Birds

S = Spiders

So, we have:

B = C = S --- equal amounts

6B + 2C + 8S = 270 --- the legs

Required

The number of spider

Since she has an equal amount of B, C and S;

The expression can be written as:

6B + 2C + 8S = 270

6S + 2S + 8S = 270

16S = 270

Solve for S

S = \frac{270}{16}

S = 16.875

<em>The result of the solution does not represent real life situation because it it is not possible to have a fraction number of spider</em>
