Answer:
x4+7x+3
Step-by-step explanation:
Mass of 1 sheet = (160 g/m^2)*(1/8 m^2) = 160/8 g = 20 g
mass of 25 sheets = (25 sheets)*(20 g/sheet) = 25*20 g = 500 g
Before budget change :
Maintenance = 1 - 1/3 - 1/3 - 1/4 = 1/12
After budget change :
Maintenance = 1 - 1/3 - 1/8 - 1/4 = 7/24
Difference in budget for maintenance = 7/24 - 1/12 = 5/12
Answer:
One solution
Step-by-step explanation:
y = 2x – 5. –8x – 4y = –20. one solution: (–2.5, 0)
<em>Subtract</em> 2/3x on both sides.
Combine 5/3x and -2/3x to get x.
Subtract 4 from both sides. <em>Any value</em> subtracted from zero results in its negative value.
