You will divide the 12 by 28: 12/28 and that equals 3/7
I think that i got it but at the same time not sure but the value of a+b should be 14+20
Answer: -2.5
Step-by-step explanation:
Hi! I know for sure that a and d are equivalent to the expression which is not what you are looking for. This is because 11 times 8 gives you the 88 on a and if you multiply the 5 also by 8 you get 40 so a is not the answer. The reason I multiply both by the same number and got the equivalency is because, "What you do to one side, you do to the other." Same thing with d. My answer would be B because you can't change the variable to a different number. You can't just give the five the y and make it mean the same. The answer is B.
