should I send diploma transcript to universities?

I applied as a math/econ major to a bunch of top 20 US universities using these IB Diploma predicted grades:

Maths HL: 7
Business HL: 7
English A Lang Lit HL: 6
Physics SL: 7
Economics SL:7
Spanish A Lang Lit SL: 5
ToK: A
EE: A
Total: 42 Points

Since I took all the tests last Novermber, I just got my Diploma results a few days ago:

Maths HL: 6
Business HL: 7
English A Lang Lit HL: 6
Physics SL: 7
Economics SL:7
Spanish A Lang Lit SL: 6
ToK: A
EE: B
Total: 42 Points

I met my predicted score, but I’m concerned that not having a 7 in math would seriously lower my admissions chances. Should I send my diploma transcript anyways, even if it isn’t requested?
