Answer:
Therefore Jenna ran 20 kilometers in a week.
Step-by-step explanation:
<u><em>Jenna ran 2 7/8 kilometers each day for a week. How far did she run in all?</em></u>
<u><em /></u>
We can simply use proportion to solve this;
But we need to know that 7 days = 1 week
If Jenna ran 2 kilometers each day, we are now going to find how many kilometers she run in a week(7 days)
Let x be the total distance she ran in a week
2 kilometers = 1 day
x = 7 day
Cross-multiply
x = 2 × 7
= × 7
=
=20 kilometers
Therefore Jenna ran 20 kilometers in a week.
So it will be
1/3(6)=-2/5(-5)
then will remove minus
1/3*6=2/5*5
then cancle 3 and 6 will be 2 and remove 5
So it become like this 2=2 it is True
Answer:
that would be 76
Step-by-step explanation:
Let x= flight 1 and y=flight 2
x=4y+5(5 more than 4 times the second flight)
y=y
x+y=365, replace x with 4y+5
4y+5+y=365, combine like terms
5y+5=365
5y+5-5=365-5
5y=360
5y/5=360/5
y=72
x=293
y=72
293+72=365
flight 2 had 72 people
Answer:
i = 7.5
Step-by-step explanation:
(5-3i)+(10+5i)
(5+10)+(5i-3i)
15+2i
15=-2i
15/2-i
7.5=i
