Answer:
D.
Step-by-step explanation:
Complementary angles are two angles whose measures add to 90°.
A.
m<CFD = 150° - 100° = 50°
m<EFD = 180° - 150° = 30°
Sum = 80°
No
B.
m<AFB = 40°
m<DFE = m<EFD = 30°
Sum = 70°
No
C.
m<AFC = 100°
Sum > 100°
No
D.
m<BFC = 100° - 40° = 60°
m<DFE = 30°
Sum = 90°
Yes
Answer: D.
One may note you never quite asked anything, now, assuming simplification,
Answer:
D. 20 ÷ 6 − 4
E. 1/6(20 − 24)
F. (20−24) ÷ 6
Step-by-step explanation:
6(x + 4) = 20
6(x) + 6(4) = 20
6x + 24 = 20
- 24 - 24
6x = -4
/6 /6
x = -4/6 or x = -2/3
D. 20 ÷ 6 − 4
20/6 - 4
20/6 - 24/6
-4/6 = -2/3
E. 1/6(20 − 24)
1/6(-4)
-4/6 = -2/3
F. (20 − 24) ÷ 6
- 4 / 6
-4/6 = -2/3
Hope this helps!
Answer:
Step-by-step explanation:
Recursive formula
a1 = -17
a^n = a^n-1 + 5
Explicit formula:
a^n = -17 + (n-1) * 5
Ten thousand - 10,000
thousand literally just haves 1,000
if the twenty is before the three zeros, it would be 20,000 which is twenty thousand. its the same with other numbers. its super simple!
