Help pleaseeeeeeeeeeee
Yuliya22 [10]

Answer:

x = 1

GF = 12

GH = 15

FH = 3

Step-by-step explanation:

G___F___H

GH = GF + FH

11x +4 = ( 3x +9) + (5x-2)

11x+4= 8x + 7

11x - 8x = 7-4

3x = 3

x =3/3

x = 1

GF = 3x + 9 = 3(1)+9=3+9=12

GH = 11x +4= 11(1)+4=11+4 = 15

FH = 5x - 2 = 5(1) - 2 = 5 - 2 = 3

I hope I helped you^_^

2 t-shirts and 3 hats costs £12.
Mariana [72]

Answer:

Cost of tshirt = £7.29

Cost of what = £0.86

Step-by-step explanation:

2t +3h = 12; 10t + 15h = 60

5t + 4h =33; 10t + 8h = 66

15h -8h = -6

7h = -6; h = -6/7; h = 0.86

2t +3(-6/7) =12

14t -18 = 84

14t = 102; t = 102/ 14; t=7.29
