To make y the subject, we must move everything to one side and y on the other.
![x + 2y = 6\\2y = 6 -x\\2y = -x + 6\\y =-\frac{1}{2} x + 3](https://tex.z-dn.net/?f=x%20%2B%202y%20%3D%206%5C%5C2y%20%3D%206%20-x%5C%5C2y%20%3D%20-x%20%2B%206%5C%5Cy%20%3D-%5Cfrac%7B1%7D%7B2%7D%20x%20%2B%203)
Good day and I hoped that helped!
What do you think?
I'd say that multiplication applied to rational numbers cannot convert any of them to irrational numbers, so I believe the answer here is YES.
Answer:
Laura will have exactly $72.00 after purchasing the bicycle.
Step-by-step explanation:
We are given that Laura ends $115 per month of babysitting.
We also learn that she wants to save her money from June and July, which means she wants to save her money over a period of two months.
Therefore, she will earn $115 twice.
![\displaystyle{\$115 \times 2 = \$230}](https://tex.z-dn.net/?f=%5Cdisplaystyle%7B%5C%24115%20%5Ctimes%202%20%3D%20%5C%24230%7D)
Then, she wants to purchase a bicycle that costs $158, so we need to subtract the cost of the bicycle from her total earnings.
![\$230 - \$158 = \$72](https://tex.z-dn.net/?f=%5C%24230%20-%20%5C%24158%20%3D%20%5C%2472)
Therefore, Laura will have exactly $72.00 remaining after her purchase.
