A clothing store sells a customer 3 T-shirts and 4 pairs of shorts for $83.

ss7ja [257]

3t + 4s = $83
4t + 1s = $50 (x 4)

16t + 4s = $200
3t + 4s = $83 (minus them£

13t = $117 (divide by 13)

t = $9

sub t into first equation.

3 x 9 = 27
27 + 4s = $83
4s = $56
s = $14

t = $9
s = $14

Pls help fast:<br>How many ways can 3 songs be chosen from 12 to create a 3 song ordered play list?

leva [86]

Answer:

1320

Step-by-step explanation:

Total number of songs = 12

Number of songs required to arrange in a play list = 3

It means we have to arrange 3 songs from 12 in the play lines. So, required number of ways is

$Ways=^{12}P_{3}$

$Ways=\dfrac{12!}{(12-3)!}$ $[\because ^nP_r=\dfrac{n!}{(n-r)!}]$

$Ways=\dfrac{12\times 11\times 10\times 9!}{9!}$

$Ways=1320$

Therefore, the required number of ways is 1320.

I need help please :(

15x + 11x + 8x+5 = 180

34x + 5 = 180

34x = 180-5

34x = 175

x = 5.147

by substitution each value by of x by 5

75 + 55 + 45 = 175
