Answer:
78.6km/h
Step-by-step explanation:
<em><u>Speed=distance÷time</u></em>
<u>distance</u>=21km
<u>time</u>=16 minutes<u>(convert into hour by dividing it</u> <u>with 60)</u>
=16÷60=0.267
Speed=21÷0.267=78.65km/h


Length times width so that would be 21

= 25.11111111
Meaning there are around 25 left
Question 3
if 7x = 28
divide both sides by 7
7x/7 = 28/7
x = 4
This is division property of equality
Question 1
if angle m is 80 degrees the m = 80 degrees
this can be a congruent angles or alternate angles are equal
this is symmetric property of equality
Question 5
m1 = 30 and mz1 = m2, then m2 = 30
this property is transitive property of equality
Question 2
if RS - TU and TU =YP, then RS = YP
this means you can substitute RS with YP
then we have our new expression as
YP - YP
this is substitution property of equality, this is because we are substituting a function with another function
