Answer:
Step-by-step explanation:
Distance=Speed×Time
75×4.8=360
Speed=distance÷time
360÷3=120km/h
Step-by-step explanation:
1. 1/4(x + 12)=2 - first isolate X'
- 12 -12
2. 1/4(x) = -10 - 1/4 since its a fraction, you'll have to subtract not divide
-1/4 - 1/4
3. x = -10.25
Andre did the first step correctly, but on the second step he just divided 1.4 by -10, instead of subtract 1/4 from both sides.
Answer:
∠ DFE = 15°
Step-by-step explanation:
The inscribed angle DFE is half the measure of its intercepted arc, that is
∠ DFE = 
DE = × 30° = 15°
2•3=9 2•2=4 2•2=4 9+4+4=17 the answer is 17
