Please help
25= 2r+3
A 28=2r
B 22=2r
C 50= r + 3
D 25/2=r3
Subtract 3 from both sides of the equation.
Oh i forgot it says which solution is the same
To determine the value of r in the equation 25 = 2r + 3, you need to isolate r on one side of the equation. Follow these steps to solve for r:
1. Start with the equation: 25 = 2r + 3.
2. Subtract 3 from both sides to move the constant term to the other side of the equation:
25 - 3 = 2r + 3 - 3.
Simplify:
22 = 2r.
3. Divide both sides by 2 to isolate r:
22/2 = 2r/2.
Simplify:
11 = r.
Therefore, the value of r in the equation 25 = 2r + 3 is 11.
Now let's analyze the options you provided:
A) 28 = 2r: This option is different from our solution of r = 11.
B) 22 = 2r: This option matches our solution, r = 11. It is a correct result based on the given equation.
C) 50 = r + 3: This option does not match the equation 25 = 2r + 3.
D) 25/2 = r3: This option is not a valid equation since it combines an integer (25) with a fraction (2 = r3).
Therefore, the correct answer is B) 22 = 2r.
