How do you solve this (3y+1)^1/2=y-1

y=-3

Step-by-step explanation:

(number)^1 is just (number)

so (3y+1)^1/2=y-1 is (3y+1)/2=y-1

multiply 2 on both side so get rid of fraction

then 3y+1=2(y-1)

3y+1=2y-2

y=-3

in simplified version   it would be x ≤-4

step-by-step explanation:

multiply each term in x ≤-4 by -1

$25

step-by-step explanation:

25 - 4.50 = 20.5

20.5 / 2 = 10.25

10.25 + 10 = 20.25

20.25 - 12.50 = 7.75

therefore the answer is $25 as shown as the first number.
