Answer:
Step-by-step explanation:
n + q = 20
.05n + .25q = 3.00
5n + 25q = 300
n + q = 20
5n + 25q = 300
-5n - 5q = -100
20q = 200
q = 10 quarters
n + 10 = 20
n = 10 nickels
(10 nickels, 10 quarters)
It is b is the answer to the question
Answer:
4
Step-by-step explanation:
80%=4/5
4/5 of 20 is 4
They lose 4 matches.
So 3 times x+3 is -18 so
3(x+3)=-18
so distribute
3x-9=-18
add 9 to both sides
3x=-27
divide both sides by 3
x=-9
Polynomials are set of expressions with variables that are usually used in operations.
*2x^2 +3x-2
2x^4+3x^3(2x^3+2x)=4x^7+4x^5+6x^6+6x^4
*(^ is the raised exponent)
