Answer: x-3=0 and 6=2x
Step-by-step explanation: to find what X equals for each equation you have to get X alone to get X alone in the first option you have to do +3 to both sides of the equal sign which leaves you with x=3 which you then do for the rest of the options an select all the one left with x=3.
8 in 2.408 is closer to 10, so you round 2.408 to 2.41
-15+7=-8
Adding numbers with different signs makes it subtraction and the answer will have the sign of the bigger number
Answer:
1.Yes
2.Yes
3.No
4.No
5.Yes
Step-by-step explanation:
Just plug in the values of x and y for each set of coordinates.
Example from the first one
4x=y
4(5)=20
20=20 True
make sure all are valid by plugging in the next set of coordinates
4(6)=24
24=24 True
4(7)=28
28=28 True
and so forth with each equation plug in the coordinates
