Answer:
Height of the recycling box = 75 cm
Explanation:
Volume of a box = Base area of box x Height of box
Volume of the box = 151875 cm³
Base has a square base of side 45 cm
Base area = 45 x 45 = 2025 cm²
151875 = 2025 x Height of box
Height of box = 151875/2025
= 75 cm
Height of the recycling box = 75 cm

Step-by-step explanation:
2x+3y=5 rearrange 2x=5-3y times all by 2 4x=10-6y
4x-3y=1 4x=1+3y
1+3y=10-6y 6y+3y=10-1 9y=9 y=1
4x-3(1)=1 4x=1+3 4x=4 x=1
