Answer key says 50, but i have no idea how to get it. can anyone please help me?
Lady_Fox [76]

Answer:

x=50

Step-by-step explanation:

note that 40% is 2/5

Therefore, 30 tomatoes is 1- 2/5 = 3/5

3/5 of the tomatoes last year is 30

lets say tomatoes = x

3/5 x = 30

divide by 3 on both sides

1/5 x = 10

multiply by 5 on both sides

x=50

:D

hope it helped :D

Solving these quadratics for x using complete the square 3x^2-4x-1=0. Show your work.
UkoKoshka [18]
Answer: x = (sqrt(7) + 2)/3 and
x = ( – sqrt(7) + 2)/3

Explanation:

3x^2 - 4x - 1 = 0

Divide both sides by 3:

3x^2/3 - 4/3x - 1/3 = 0/3
x^2 - 4/3x - 1/3 = 0
x^2 - 4/3x = 1/3
x^2 - 4/3x + (2/3)^2 = 1/3 + (2/3)^2
(x - 2/3)^2 = 1/3 + 4/9
(x - 2/3)^2 = 7/9

Sqrt both sides:

x - 2/3 = sqrt (7/9)
x - 2/3 = |sqrt(7)/3|

Set x -2/3 = sqrt(7)/3

=> x = (sqrt(7) + 2)/3

Set x - 2/3 = - sqrt(7)/3

=> x = ( - sqrt(7) + 2)/3
