Answer:
66
Step-by-step explanation:
Open the parentheses, 18 + 72 - 16 - 8 = 66
Answer:
0.6
Step-by-step explanation:
2×3x+4+4=12
6X+8=12
6x=12-8
6x=4
Divide by 6
X=0.6
Answer:
90x+10y
Step-by-step explanation:
Add 89 and 1
Add 5 and 5
90x+10y in this order
Angle BOC = 120
PROOF
Angle A + Angle B + Angle C = 180
So, Angle B + Angle C = 120 (Angle A = 60)
Now 1/2 (Angle B + Angle C) = 60
1/2 Angle B + 1/2 Angle C = 60..............i
In triangle BOC
1/2 Angle B + 1/2 Angle C + Angle BOC =180
(BO and CO are angle bisectors)
Or 60 + Angle BOC = 180 (using i)
OR ANGLE BOC = 120
The answer is the first one. 524.96 - 32.50 + x ≥ 500; x ≥ $7.54
