The sides are 2x, 3x-5 and 4x+2
perimiter is the sum of the sides
a.
2x+3x-5+4x+2=63 is an equation
b.
solve
group like terms
2x+3x+4x-5+2=65
add like terms
9x-3=65
add 3 to both sides
9x=68
divide both sides by 9
x=68/9
2x=2(68/9)=136/9 in
3x-5=3(68/9)-5=(68/3)-5=(68/3)-(15/3)=53/3
4x+2=4(68/9)+2=272/9+2=272/9+18/2=290/9
the side lengths are 136/9in, 53/3in, and 290/9in
Answer:
2437.5 Miles
Step-by-step explanation:
first find how many miles 1 inch is 625/5 = 125
next you multiply 19.5 * 125 = 2437.5 miles
Hello!
Mode :

Given observations are :-
22,40,21,18,47,22,19
Now , mode =

The answer is 22 as it appears two times in the given set of observations.
Hope this is clear :)
Have a good day:)
Answer:
the best option would be to swim
Step-by-step explanation:
Hello! To solve this problem we must follow the following steps.
1. remember the concept of uniform motion with constant speed, which establishes the following equation

where
t=time
x=distance
V=speed
2. Calculate the time it takes to swim and calculate the time it takes to walk
walking:
x=10mile
v=5milles/h

swimming
x=1mile
v=3milles/h

3. Compare both results and choose the one with the least time.
as you can see it takes less time swimming, so this would be the best way
They would be alternate exterior so they would have to to be equal
2k + 11 = 131
-11 -11
2k = 120
---- -----
2k 2k
k = 60
