Janine used the calculations shown to determine how much she would spend on 245 pencils. 3,600 pencils cost 72 dollars. (StartFraction 72 dollars Over 3,600 EndFraction) (StartFraction question mark Over 1 EndFraction) What is her error? She placed the decimal point incorrectly when dividing. She placed the decimal point incorrectly when multiplying. She wrote the rate incorrectly. She did not make an error.

answer: no

step-by-step explanation:

you are only given the cost not the amount of pounds.

x =±sqrt(1/3)

step-by-step explanation:

x+4/6x=1/x

multiply each side by 6x to get rid of the fractions

6x*(x+4/6x)=1/x*6x

distribute

6x^2 +4 = 6

subtract 4 from each side

6x^2 +4-4 = 6-4

6x^2 =2

divide by 6

6x^2/6 = 2/6

x^2 = 1/3

take the square root of each side

sqrt(x^2) = ±sqrt(1/3)

x =±sqrt(1/3)

i think is g(1)=-1.

hope that i can

-2x + 7 = 7

subtract 7 from both sides.

-2x = 0

divide both sides by -2.

x = 0
