3) A linear equation to represent this would be 205 = 10x + b
x is days passed, which is 10, and b is the original amount.
10 times 10 is 100, so we now have 205 = 100 + b
Subtract 100 from both sides to get 105 = b, which is the starting amount.
The rate of change is 10, however many cans brought per day.
4) So it appears that for every 5 minutes she frosts 4 cupcakes, which means the rate of change is 4/5 using rise over run.
Subtract 4 from 28 to get the starting amount 5 minutes earlier.
The starting amount of frosted cupcakes is 24.
5) Every 3 months he gets 9 more CDS. So, every month he gets 3 new CDs.
That means the slope is 3.
Subtract 9 from 18 to get the starting amount.
The starting amount of CDs is 9.
Hope this helps!
If 1 mile is equal to 1.6 km, then our dimensional analysis would be set up like this to solve for m per hour: 
. The miles label cancels out leaving us with kkm per hour. Doing that multiplication gives us 12.8 km in one hour. If she can go 12.8 m in one hour, then we multiply that by 2 to find out how far she can go in 2 hours. 12.8*2 = 25.6 km in 2 hours.
Answer:
24 cm squared
Step-by-step explanation:
Answer:
Area of a rectangle is Width * Length
Apply this to each area the question asks for
AreaTop = 8cm * 4cm = 32
AreaBottom = the same, 32
AreaFront = 2cm * 4cm = 8
AreaBack = the same, 8
AreaLeftSide = 2cm * 8cm = 16
AreaRightSide = the same, 16
TotalSurfaceArea = 16 + 16 + 8 + 8 + 32 + 32 = 112
