Write a pair of numbers such that the value of the 7 in the first number is 1000 times the value of the 7 in the second number,
telo118 [61]

<u>Answer-</u>

As infinitely many such possible number pairs can be formed, one of the instances of such pair would be (37000 and 307).

<u>Solution-</u>

Suppose the former one is aaaaa and the later one is bbbbb.

The value of 7 in the former is 1000 times greater than in the later, so let's make it 7000 and 7.

Then the numbers will be in the following form,

a7aaa and bbbb7

Again, the value of 3 in the former is 100 times greater than in the later.

Then the numbers will be in the following form,

37aaa and bb3bb7

Substituting all the a's and b's by 0,

we get, 37000 and 307 is a possible set. Replacing 0 with any number from 1-9, will yield another number pair which will satisfy the conditions.

4x - 3y = 15<br> 2x + 2y = 4<br><br> what is the solution of the system of equations?
klio [65]

Answer:

System of Linear Equations entered :

  [1]    4x - 3y = 15

  [2]    2x + 2y = 4

Step-by-step explanation:

// Solve equation [2] for the variable  y  

 

 [2]    2y = -2x + 4

 [2]    y = -x + 2

// Plug this in for variable  y  in equation [1]

  [1]    4x - 3•(-x +2) = 15

  [1]    7x = 21

// Solve equation [1] for the variable  x  

  [1]    7x = 21  

  [1]    x = 3  

// By now we know this much :

   x = 3

   y = -x+2

// Use the  x  value to solve for  y  

   y = -(3)+2 = -1  

Solution :

{x,y} = {3,-1}

Which literal equations are equivalent to m=w/g? a) g=w/m; b) g=m/w; c) w=mg; d) w=m/g
Charra [1.4K]
A) g=w/m
d) w=m/g
It introduces the relationship between two variables and is called correlation. 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. This correlations are important to consider because you can determine and identify how two variables relates with one another. Notice x = y (direct), y=1/x (indirect)
