Answer:
I have a answer for the second question. The better buy would be 69 cents for 18in. I say this because in each foot there is 12 in right, 18 in is a foot and 6 in. if you buy two 18 in wires it will cost $1.38 for 3 feet of wire which is cheaper then $1.49.

Answer:
$9.70
Step-by-step explanation:
Use PEMDAS:
Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right).
Problem:
C(x) = 0.06x + 8.50
Substitute x for 20:
C(20) = 0.06(20) + 8.50
Multiply 0.06 and 20:
C(20) = 1.2 + 8.50
Add 1.2 and 8.50:
C(20) = $9.70
The total cost for an order of 20 copies is $9.70

I did the test and I got it right.
Answer:
A 175/979 = M
Step-by-step explanation:
Si Matusalén vivió 979 años y Abraham vivió 175 esto quiere decir que abraham vivio menos años que Matusalén.
Por lo que la fracción va a tener que ser menor que 1 ya que al multiplicarla por la edad de Matusalén nos tiene que dar la de Abraham.
Tenemos que encontrar una fraccion que multiplicada por 979 nos de 175.
979 * X = 175
Tenemos que despejar la x y encontraremos el valor de la fraccion.
979 * X = 175
X = 175/979
Nos fijamos si se puede simplificar, no se puede asique este es el resultado final.
