Answer:
A tape diagram. StartFraction part Over whole EndFraction = StartFraction 300 Over 100 EndFraction = StartFraction 75
Step-by-step explanation:
Answer:(-10,-23)
Step-by-step explanation:
Okay....the easiest way to answer this would be either elimination or graphing. However, you could also use substitution.
Right now, I'll show how to use it by elimination.
First this is to convert both equations to standard form (x+y=__)
What we'll do for the first one is add 3x to each side. We end up with this:
-3x+y=7
Then subtract 2x from the other one. Ending up with:
-2x+y=-3
Now, we eliminate the y by subtracting.
-3x+y=7
(-) -2x+y=-3
___________
-x =10
x = -10
Now, plug in the x to one of the equations.
y=2(-10)-3
y=-20-3
y=-23
Make sure to check your answer by plugging both into the equations.
X=-10
Y=-23

Answer:
There are total 5 layers.
Step-by-step explanation:
A multi-layer cake is in the shape of a right cylinder.
Height of the cake is = 20 cm
Radius is = 10 cm
Each of the cake layers has a volume of approximately 1,250 cm³.
Means, the volume of 1 cylindrical layer is 1250 cubic cm with radius as 10 cm and we have to find the height.
Volume of the cylinder is given as:
h = 3.98 or approximately height of 1 layer is 4 cm.
As the cake's height is 20 cm so, there are 
layers in the cake.
Answer: There are 5 layers in the cake.
