Beth walks dogs after school to earn spending money. If she gets $15 per week, plus an extra $3 for each dog she walks, and she earned $54 last week, how many dogs did Beth walk?

54-15=39÷3=13 dogs is the answer

x = ± 6i

step-by-step explanation:

x^2 = -36

take the square root of each side

sqrt(x^2) = sqrt(-36)

we know sqrt(ab) = sqrt(a) sqrt(b)

x = ±sqrt(36) sqrt(-1)

we know that sqrt (-1) = i

x = ± 6i

answer: there are 453.592 grams in a pound.
