Answer:
any value of a makes the equation true.
Step-by-step explanation:
R = x(A+B)
distribute
R=Ax+Bx
subtract Ax from each side
R-Ax=Bx
divideby x
(R-Ax)/x =B
Choice C
Answer: The answer is - x-5/4
Step-by-step explanation:
1/10 4/5 we need common denominaters so
1/10 4(2)/(5)= 8/10
The answer is -3. Now imagine a line of numbers from -4 to +4. Your first number in that line would be +2. From there you would be moving to the left since you're taking numbers away and in this case you're taking away +5. So when you're going on that line from +2 tho the left by +5 it gets you to -3. I hope you understand what I'm trying to say:D I also included the photo of that "line".
