If it doesn't matter whether the points are integers or not you can just pick a number for either y or x and solve for the other variable. For example, if you pick 3 to be your x, plug it in and then solve for y. Start out with:
![7x-3y=42](https://tex.z-dn.net/?f=7x-3y%3D42)
Plug in 3 for x:
![7(3)-3y=42](https://tex.z-dn.net/?f=7%283%29-3y%3D42)
. Then,
![21-3y=42](https://tex.z-dn.net/?f=21-3y%3D42)
. Subtract 21 from both sides and then divide by -3 on both sides. You end up with y=-7 so one of your points is (3, -7)
You basically just take 3^2 and 2^2 to get 9/4
9/4 is the answer
Answer:$43.29
Step-by-step explanation:
Answer:
You need to cross multiply 37/45+x/100 which equals 17%
Step-by-step explanation:
The first part represents the 37 dollars out of the original 45 and the second part represents x= the unknown percent out of 100 percent. This would be 17%
You divide 42 by 3 then multiply what you get times 5. it should equal 60 cm
