<span>lets assume number of iphones sold = a number of ipads sold = b i sold 4 iphones more than ipad that becomes a = b+4 then the equation of total commission becomes 30a+20b = 520 substituting a =b+4 in the above equation 30(b+4)+20b = 520 30b+120+20b = 520 50b =520-120 50b = 400 b = 400/50 b=8 number of iphones i sold = a = b+4 = 8+4 = 12 number of ipads i sold = 8 so i sold 12 iphones and 8 ipads to earn the commission of $520</span>

1.

3 x 4 = 12

3 + 4 = 12

The two integers a and b are : 3 and 4


2.

-4 x 1 = -4

-4 + 1 = -3

The two integers a and b are : -4 and 1


3.

-3 x -3 = 9

-3 + -3 = -6

The two integers a and b are : -3 and -3


There you go! I really hope this helped, if there's anything just let me know! :)

What is the distance between points v (3,3) and w (-2,-3) round to the nearest tenth if necessary
Vinil7 [7]

Answer:

7.81 u

Step-by-step explanation:

<u>Given :- </u>

  • Two points (3,3) and (-2,-3) is given to us.

And we need to find out the distance between the two points . So , here we can use the distance formula to find out the distance. As,

:\implies D = √{(x2-x1)² + (y2-y1)²}

:\implies D =√[ (3+2)² +(-3-3)²]

:\implies D =√[ 5² +6²]

:\implies D =√[ 25 +36]

:\implies D = 61

:\implies D = 7.81

<h3>Hence the distance between the two points is 7.81 units .</h3>
