( - 14x^3)(y^3) + 4x^5y^6)/(2x^4y^5)
= 4x^5y^6 - 14x^3y^3/2x^4y^5
= 4x^2y^3 - 14/2xy^2
= 2x^2y^3 - 7/xy^2
Answer: 2x^2y^3 - 7/xy^2
Hope that helps!!!!
30 = 5(m) + 7(n)
5(a) + 30 = 7(a)
(a) is the number of visits!
15 = (a)
5(15) = 75 + 30 = 7(15) = $105
The pythagorean theorem equation is a^2 (a squared) + b^2 (b squared) = c^2 (c squared)
so a^2+b^2=c^2
Answer:
4
Step-by-step explanation:
1. if the mass of coffee worth $10 is 'x', then its worth is 10x, and the worth of the mixture is 5(x+20);
2. using the previous item it is possible to write the next equation:
5(x+20)=4*20+10*x; ⇒ x=4.
3. the required mass is 4 pounds.
The answer is (3,2)
To get this answer we either...
A) Multiply both coordinates by 1/3
or
B) Divide each coordinate by 3
9*(1/3) = 9/3 = 3
6*(1/3) = 6/3 = 2
