Let the price of a notebook = X.
Multiply the cost of a notebook by the quantity, so you get 3x.
Add that to the price of a calculator to get the total spent:
60.54 = 45.87 + 3x
Now solve for x:
Subtract the cost of the calculator from both sides:
3x = 14.67
Divide both sides by 3:
x = 14.67 / 3
x = 4.89
A notebook cost $4.89
This is the concept of algebra, given a polynomial with one variable like x and y, the degree is the largest exponent of the variable;
Given the expressions;
4x^3-2y^3+5y^2-5y The polynomial has a degree of 3 (both y and x have an exponent of 3)
3y3--xy=3y^3+xy The polynomial has a degree of 3 also (y has an exponent of 3)
Answer:
- 2 - 4n - 8n²
Step-by-step explanation:
thats ur anser
10•8=80
so something times 80 will equal 400
80•5=400
C=2pr, r=c/(2p)
a=pr^2, using r found above we get:
a=p(c^2/(4p^2))
a=(c^2)/(4p), since c=106.76 and we approximate pi as 3.14
a=(106.76^2)/(4*3.14)
a=11612.2176/12.56 cm^2
a≈924.54 cm^2 (to nearest one-hundredth of a square cm)
