Answer:

9x+8=23 HOPE THIS HELPS

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

17+7x−9=19−2x+4

17+7x+−9=19+−2x+4

(7x)+(17+−9)=(−2x)+(19+4)(Combine Like Terms)

7x+8=−2x+23

Step 2: Add 2x to both sides.

7x+8+2x=−2x+23+2x

9x+8=23

Step 3: Subtract 8 from both sides.

9x+8−8=23−8

9x=15

Step 4: Divide both sides by 9.

9x /9 = 15 /9

x= 5 /3

If a hen and a half lay an egg and a half in a day and a half, how many eggs will half a dozen hens lay in half a dozen days?

BlackZzzverrR [31]

Answer:

72 eggs

Step-by-step explanation:

Let’s simplify the answer: if one and a half hens lay an egg in 18 hours, how many eggs will 6 hens lay in 6 days? So 18/3=6, and 6x2=12. One hen can lay an egg in 12 hours. Which means a hen can lay 2 eggs in one day. 2x6=12. So 6 hens can lay 12 eggs in one day. 12x6=72. In 6 days, 6 hens can lay 72 eggs
