15 1/3 envelopes in 1 minutes
Step-by-step explanation:
Take the number of envelopes and divide by the number of minutes
460 envelopes / 30 minutes
15.333333.... envelopes per minute

Answer: B, 5.5
Step-by-step explanation:
4+4+4+5+5+6+6+6+6+9=55
55/10=5.5
8.525 is rounded to 8.53 because the 5 rounds up so the 2 turns into a 3
Answer:
What are the choices?
Step-by-step explanation:
Answer:
X= 1 AND 13
Step-by-step explanation:
x2+14x = -13
by completing the square method
you add the square of half the coefficient of b to both sides
which is (14/2)^2
x^2+14x+(7^2) = -13 +(7^2)
x^2 + 7^2 = -13 + 49
x^2 + 7^2 = 36
(x + 7)^2 = 36
find the square root of both sides
(x+7) = + or - 6
x=7-6 ; 1
or
x= 7+6 ; 13
