To solve for b, we can start by isolating b on one side of the equation.
4a = 2b - 7
Adding 7 to both sides of the equation:
4a + 7 = 2b
Dividing both sides of the equation by 2:
2a + 3.5 = b
So, the value of b when a = 3 is:
2(3) + 3.5 = 6 + 3.5 = 9.5
Therefore, the correct response is: Image with alt text: nineteen-halves
4a = 2b - 7
Adding 7 to both sides of the equation:
4a + 7 = 2b
Dividing both sides of the equation by 2:
2a + 3.5 = b
So, the value of b when a = 3 is:
2(3) + 3.5 = 6 + 3.5 = 9.5
Therefore, the correct response is: Image with alt text: nineteen-halves
