Hey there!
This equation has infinite solutions.
To solve for this equation, first add -7 to both sides in order to get rid of the constant:
2x-2x-7=-7
2x-2x=0
Now, combine your like terms or add 2x and -2x together:
2x-2x=0
0=0
Because you result in a true mathematical statement (0 is equal to itself), you have an infinite amount of solutions or all real solutions.
To check if this is true, plug in any number in place of x in the original staeltement to see if you result in a true statement:
Let's say x is 5
2(5)-2(5)-7=-7
10-10-7=-7
-7=-7
This proves that you have infinite solutions for your equation. :)
The circumference is calculated through the equation,
C = 2πr
where C is circumference and r is radius.
Earth:
C = 2π(6371 km)
= 40030.17 km
Moon:
C = 2π(1737.5 km)
= 10917.03 km
The difference between the two circumferences is approximately 29113.13 km.
C. y= [25,100]
you need brackets because the points actually touch the number
