Answer:
55
Step-by-step explanation:
1st you would find the equation which would be (16 + 6.50x) = (10 + 7.50x) then you would find the answer which would be x = 6 then you would do 6.50 times 6 which would give u 39 add that to 16 which is 55 and do the same on the other side (7.50 times 6) which would give u 45 and then add the 10 which is 55 so the answer is 55.
2 + 3 = 5
1/3 + 1/3 = 2/3
Your answer is 5 2/3
hope this helps
Answer:
A 5
Step-by-step explanation:
Parts on the left have the same ratio as parts on the right.
... x/(x+5) = (x -2)/(x +1)
Multiplying by (x+5)(x+1), we get
... x(x +1) = (x -2)(x +5)
... x² +x = x² +3x -10 . . . . eliminate parentheses
... 0 = 2x -10 . . . . . . . . . . subtract x²+x
... 0 = x -5 . . . . . . . . . . . . divide by 2
... 5 = x . . . . . . . . . . . . . . . add 5
