85 / 5
(50 + 35) / 5 =
(50/5) + (35/5) =
10 + 7 = 17
Since the 90% is 63. divide it by 9. then you would get value of 7. then multiple it by 10.
which is equal to 70. so 100% is 70.
68.40 divide 6 = 11.4
41.80 divided 4= 10.45

Answer:
x = -11/2
Step-by-step explanation:
The ratios need to stay the same
5x 11
----- = -------
x-2 3
Using cross products
5x*3 = (x-2) 11
15x = 11x - 22
Subtract 11 from each side
15x-11x = -22
4x = -22
x = -22/4
x = -11/2
When a number is next to a variable multiply so you problem really is 2(?)=60
