The answer to your question is 38 packs
Step-by-step explanation:
Data
570 crayons
packs of 15 crayons each
total number of crayons = ?
Process
To solve this problem just divide the number of crayons by the number of crayons in each pack.
38
15 570
-45
120
- 120
0
Conclusion
Nancy bought 38 packs to have 570 crayons.
First, you can section the polygon in the regular shapes.
Now, we can find the area of the bigger polygons. We will multiply 4x3 to get an area of 12 units^2. Then, we do 4x2 to get the area of the smaller polygon. This would be 8 units^2
12+8 is 20
To decompose a fraction to one whole, there are different methods to use. The fraction can be decomposed either by division, multiplication(if there are more than one fraction), or addition(if there are more than one fractions).
Example:
Given 8/2, decompose by division:
To do this, divide the numerator by denominator
Y=4x²-7x+13
y-13=4(x²-(7/4)x)
y-13+4*(7/8)²=4(x²-2*(7/8)x+(7/8)²)
y-13+4*(7/8)²=4(x-(7/8))²
y-13+ 3.0625=4(x-0.875)²
y-9.9375=4(x-0.875)²
y=4(x-0.875)² +9.9375
