Answer:

10.5 is the answer

Step-by-step explanation:

4(5y−8−2)=185−15

(4)(5y)+(4)(−8)+(4)(−2)=185+−15(Distribute)

20y+−32+−8=185+−15

(20y)+(−32+−8)=(185+−15)(Combine Like Terms)

20y+−40=170

20y−40=170

20y−40+40=170+40

20y=210

20y/20=210/20

y=21/2

y=10.5

Answer: p=8

Step-by-step explanation:

4p-11=21

4p-11-(21)=0

We add all the numbers together, and all the variables

4p-32=0

We move all terms containing p to the left, all other terms to the right

4p=32

Answer:

Rs. 4266.67(approx) will be paid for gazing 20 cows for 8 weeks.

Explanation:

A shepherd is paid rs. 2400 for gazing 18 cows for 5 weeks .

⇒ Number of money paid for gazing 1 cow for 1 week is, $\frac{2400}{18\times 5} =\frac{400}{15}= \frac{80}{3}$

then,

for gazing 20 cows for 8 weeks is= Rs. $\frac{80}{3}\times (20\times 8)$

Therefore, the amount paid for gazing 20 cows for 8 weeks is, $\frac{80 \times 160}{3} = \frac{12800}{3} = Rs. 4266.66667$ or Rs. 4266.67(approx)
