Answer:
1/10 = 2/20
1/3 = 3/9
5/7 = 15/21
Step-by-step explanation:
2t-2=26
first you would add 2 to both sides
that equals 2t=28
then you would divide both sides by two
that would give you
t= 14
Question 10: P=28cm
if l=8 and w=6
Then (8+6)=14
2(14) so 14x2 = 28
So therefore P=28cm
We know that time is distance over velocity, that is:
time = distance / velocity
t = d / v
Now from the given:
d / 460 + d / 500 = 4.8
Now we can find for d:
d = 4.8 / [1/460 + 1/500]
d = 1150 miles
So the time of each flight is:
flight = 1150 / 460 = 2.5 hours
<span>return flight = 1150 / 500 = 2.3 hours</span>
