You and a friend both work two different jobs. the system of linear equations represents the total earnings for x hours worked a
t the fi earns twice as much as you. a. one week, both of you work 4 hours at the fi rst job and y hours worked at the second job. your friend rst job. how many hours do you and your friend work at the second job?
Me : 4 x + 8 y = 64 My friend: 8 x + 16 y = 128 A ) 4 * 4 + 8 y = 64 16 + 8 y = 64 8 y = 64 - 16 8 y = 48 y = 48 : 8 y = 6 ( me and my friend work 6 hours at the second job ) B ) The number of hours we each work at the first job are also the same.
The answer is 14. This is because 0.30 multiplied by 5 is 1.5. Then 6 multiplied by 0.25 is 1.5 as well. Adding these two together is 3. 3 plus 3 for the notebook is 6. Than 6 plus 8 dollar tax is 14 dollars.
