Answer 1

Step-by-step explanation:

1)

Boys= 3x

Girls= 2x

Boys= 45

3x=45

x=15

Girls= 2×15= 30 girls

2)

Width= 3x

Length= 5x

Length= 10.5 cm

5x= 10.5

x= 10.5/5= 2.1 cm

Width= 3×2.1= 6.3 cm

3)

Amount of 4 pieces= 42 dollars

Amount of 1 piece= 42/4= 10.5

Amount of 6 pieces= 10.5×6= 63 dollars

4)

Anwar will receive= 2x

Marya will receive= 4x

Total chocolates= 54

2x+4x=54

6x=54

x=9

Marya will receive 36 chocolates.

5)
