20*5= 100
375+100=475
475/5= 95
Therefore the original price of a sweater is $95
Check the picture below.
since chords NQ and MP cross the center of the circle at R, that means that those two chords are diametrical chords and the angles made by both are vertical angles and thus twin angles, namely both are 18° as you see in the picture, so the angle NMP in magenta is really 162° + 18° + 18° = 198°, and we know the radius NR is 8.

Answer:
30+ 15 =45
Step-by-step explanation:
(3×10)+15 =45
Answer:
BRAINLY PLEASE
Step-by-step explanation:
y=-3x+2
Since it starts with 2 envelopes, subtract 2 from 17 to get how many and in all 3 packs.
17 - 2 = 15
Now, we divide that number by 3 to get how many are in each envelope.
15 / 3 = 5
There are 5 envelopes in each pack.
