if you know the tables then you can do that easily.
Answer:
S = 50w + 75
Step-by-step explanation:
After each week, Mike gains $50.
Letting w = 0 gives us the amount he started with. In this case, that would be $75.
Therefore, the equation is S = 50w + 75.
72 is 50 or above so you round it up.
<u />572 to the nearest hundred is <u>600</u>
K=4
add seven on both sides
2x-4y=7
add 4y on both sides
2x=7+4y
divide 2 on both sides
x=7+4y/2
plug that into original equation
2(7+4y/2)-4y-7=0
7 and 4y cancel out
2(2)=0
4=0
