Answer:
d = 4
Step-by-step explanation:
- 6 - d = 6 - 4d ( add 4d to both sides )
- 6 + 3d = 6 ( add 6 to both sides )
3d = 12 ( divide both sides by 3 )
d = 4
Percent change=100 times change/original
change=original-new
change=90-84.50=5.5
percent change=100 times 5.5/90
percent change=550/90
percent change=6.11111
percent change=6.1%
for all of them calcuate whats in the prenteces first then use those numbers to solve the rest of the problem
Answer:
101°
Step-by-step explanation:
20 + 25 = 45
3+2 = 5
5x + 45 = 180
Subtract 45 from 45 and 180 (both sides)
5x = 135
Divide 5x and 135 (both sides) by 5, to finally get..
x=27
3 x 27 + 20 = 101
2 x 27 + 25 = 79
Angle B.O.C = 79
Angle A.O.B = 101
