Step-by-step explanation:
i)
2(x+2)=7
2x+4=7
2x=7-4
2x=3
x=3/2
ii)3x + y =8 , y=x
3x + x = 8
4x = 8
x = 2
y≥25x+2000
because the +2000 is the y intercept ( where he started) and its 25x because he gets 25 over x amount of weeks
To solve this, you would divide the miles by the number of hours, 21 / 4
21 divided by 4 equals 5.25
