you simply have to add all of the numbers together, so it'll be 2+5+12+7+1 or 27, therefore the answer is B
2/7x+6=10. Subtract 6 from both sides
-6. -6
(7/2) 2/7x= 4 (7/2) Multiply both sides by the reciprocal of 2/7
X= 14. The fractions cancels out and x=14
Answer: I think the correct answer is D.
Answer:
Step-by-step explanation:
I don't know if I did it right but here's my guess. I think you multiply 7 by 20% and that gives you 1.40 as a result. Compared to the other method I used (division), I'm pretty sure I'm right since the other result was 35. Doesn't make sense if the end amount was $7.
