Answer:

2) x - y =  \frac{2}{3}

=  > x =  \frac{2}{3}  + y =  \frac{2 + 3y}{3}

3) 3x + 2y = 6

=  > 3x = 6 - 2y

=  > x =  \frac{6 - 2y}{3}

4) \frac{1}{4} x + y = 2

=  > y = 2 -  \frac{x}{4}  =  \frac{8 - x}{4}

5) 4x - 3y =  - 33

=  >  3y  = 4x + 33

=  > y =  \frac{4x + 33}{3}

Father can do the job on the farm in 6 hours. The older son can do it in 8 hours. The younger son can do same job in 12 hours. H
FrozenT [24]

Answer: it will take a combined rate of 2.67 hours

Step-by-step explanation:

Father can do the job on the farm in 6 hours. This means that the father's unit rate of working will be 1/6

The older son can do it in 8 hours. This means that the older son's rate of working will be 1/8

The younger son can do same job in 12 hours. This means that the younger son's working rate is 1/12

When they work together, they will be working simultaneously. It means that their unit rates are additive. The combined unit rates will be

1/6 + 1/8 + 1/12 = (20 + 15 + 10)/120

45/120

Assuming it takes t hours for them to complete the work while doing it together. Their combined unit rate will be 1/t

45/120 = 1/t

45t = 120

t = 120/45 = 2.67 hours

Write sin(19°) in terms of cosine.
Leto [7]

Answer:

cos(71)

Step-by-step explanation:

Since 19° is less than 90, we can express this in terms of confunction.

sin(θ) = cos(90-θ)

sin(19) = cos(90-19)

sin(19) = cos(71)
