5y-10x=35 would be what I recommend
Answer-
C + 5 = x
C showing how many charms Jenny has on her bracelet.
5 for the number of how many more her sister has.
X for the final sum.
Using sin law;
sin A/ a = sinB/ b
where A = C or 90 degrees; a = 21
B = ? , b = 8
solving for b;
sin(90) / 21 = sin(B) / 8 ; B = 22.39 degrees
Total angle of triangle = 180
180 - 90 - 22.39 = x
x = 67.607 degrees
If you are asking if 8.25 is greater than than 8.250, the answer would be no because any zero that is extended from the original number would still be the same.
ex: 6.2 and 6.200000000
(The zeros could go on forever and it would still be the same number)
