Answer:
9/10
Step-by-step explanation:
first you find the lowest common denominator. 1/2 becomes 5/10, 2/5 becomes 4/10. 5/10+4/10=9/10
Let x be the amount of nickels and y be the amount of quarters in a jar. Totally there are 87 coins, then x+y=87.
Since nickel is 5 cent coin and quarter is 25 cent coin, then 5x+25y=1255 ($12.55=1255 cents). Solve this system:x=87-y and 5(87-y)+25y=1255.
435-5y+25y=1255,
25y-5y=1255-435,
20y=820,
y=820÷20,
y=41,
x=87-41=46.
Answer: 46 nickels and 41 quarters.

Answer:
9/16 x^2y^3
Step-by-step explanation:
(3x^2y^5)^3/(2xy^3)^4
= 3^2 x^6 y^15 / 2^4 x^4 y^12
=9/16 x^(6 - 4) y^(15 - 12)
= 9/16 x^2y^3
Answer:
always
Step-by-step explanation:
this product can also be written as a^2 - ab - ab + b^2
which is a^2 - 2(ab) + b^2
a perfect square trinomials equation is
a^2 + 2(ab) + b^2
and this qualifies
