total distance travelled=72+69=141
time taken in hours for journey= (48/60)h + (69/60)= 1.95 h
average speed=141km/1.95h= 72.3km/h (3 sf)
Answer:
m∠1 = 89°
Step-by-step explanation:
Since m∠2 is a part of ∠GFH, he can do the following.
∠GFH - m∠2 = m∠1
133° - 44° = 89°
Answer:
<u>-2</u>
Step-by-step explanation:
<u>Given</u> :
- An example of a coefficient ⇒ '11' in 11kk
<u>Solving</u> :
- The coefficient is the part that precedes the variable(s)
- Therefore, on solving -k - k
- ⇒ -2k
- ⇒ <u>-2 is the coefficient</u>
12x-5y=2
-5y=2-12x
y=-2/5+12/5x
should know the m=12/5
and (2,3) bring them to the line equation:
3=12/5x2+b
6/5+b=3
b=3-6/5
b=9/5
y=12/5x+9/5
Which means the answer is not in the choices.
