The expression simplifies to 3a-21
The answer would be B because you have to multiply 1/3 by 3 to get a whole cup. Therefore, you have to multiply 1/4 by 3 also. In this case, the answer would be 3/4. Hope this helps!
Answer:

Explanation:
8c + 3 = −40c − 10
[ Step 1: Add 40c to both sides ]
8c + 3 + 40c = −40c − 10 + 40c
48c + 3 = −10
[ Step 2: Subtract 3 from both sides ]
48c + 3 − 3 = −10 − 3
48c = −13
[ Step 3: Divide both sides by 48 ]
48c / 48 = −13 / 48
C = -13 / 48 or -0.27083333333
