Describe and correct any error a student may have made when solving the equation 0.15(y -0.2) = 2 - 0.5(1 - y).

0.15(y -0.2) = 2-0.5(1 - y)

0.15y - 0.3 = 2-0.5 + 0.5y

0.15y - 0.3 = 1.5 + 0.5y

100(0.15y -0.3) = 100(1.5 +0.5y)

15y - 30 = 150 + 50y

15y - 30 - 15y - 150 = 150 + 50y - 15y - 150

-180 = 35y

of that equation should be The correct answer is y=

(Simplify your answers.)

i think the amount would be $140.62

step-by-step explanation:

a cube has 6 sides

the probability of getting 5 on the first cube is 1/6 since only one side of the cube has 5 on it.

there are 3 sides of the cube with even number on it [2,4,6]

therefore the probability of getting even number is 3/6

for both events to happen together, the probability would be

1/6 x 3/6 = 12/36

which simplifies to 1/12

t= half of the arc subtended by t.

r= half of the arc subtended by r.  

t+r= half of the arc subtended by t + half of the arc subtended by r= half of 360=180
