A sales associate in a department store earns a commission on each suit and each pair of shoes sold. One week, she earned $47 in
earnstyle [38]
3s + h = $47
7s + 2h= $107


3s + h =$47
3s - 3s + h = $47 -3s
h = $47 - 3s

7s + 2($47 - 3s) = $107
7s + 94 -6s = 107
s + 94 = 107
s +94 -94 = 107- 94
s = 13

3(13) + h = $47
39 + h =$47
39 -39 + h= $47-39
h = 8

Check
7s + 2h= $107
7(13) + 2(8)= $107
91 + 16= 107
107 = 107

She earns $13 per suit sold and $8 per pair of shoes sold.

Please help, I beg of y'all <br><br>FIND BD -
puteri [66]

9514 1404 393

Answer:

  14 units

Step-by-step explanation:

The angle bisector divides the sides proportionally.

  BD/BA = CD/CA

  (x+4)/8 = (2x+1)/12

  3(x +4) = 2(2x +1) . . . . . multiply by 24 (the least common denominator)

  3x +12 = 4x +2 . . . . . . . eliminate parentheses using the distributive property

  12 = x +2 . . . . . . . subtract 3x

  10 = x . . . . . . . . . subtract 2

Then the length of BD is ...

  BD = x +4

  BD = 10 +4 . . . . substitute the value of x

  BD = 14

Solve the equation 4*e+2=1 (mod5)
otez555 [7]

Here's a way to do it.

Let 4e +2 = 5n +1 . . . . . . for some integer n

Then e = (5n -1)/4 = n + (n -1)/4

We want (n-1)/4 to be an integer, so let it be integer m.

... m = (n -1)/4

... 4m = n -1

... 4m +1 = n

Substituting this into our expression for e gives

... e = (5(4m+1) -1)/4 = (20m +4)/4 = 5m +1

e = 5m+1 for any integer m
