So solving this you would change the greater than sign to an equal sign 3+4n=31 then you would solve this by subtracting 3 from 31 which gives you 28 so then you have 4n=28 then you divide each side by 4 to get n by itself which gives you n=7 so then you would change back the sign to n>7
the other problem you would do the same thing so 2n-6=18 the first step you would do is add 6 to both sides, 2n=12 then divide both sides by 2 n= 6 then change back the sign n<6 (less than or equal to) make sure to add the dash under the last problem i just couldn’t add it to this on my phone.
1/10 as a decimal would be 0.1. Now just add the 8 to it and it would be 8.1.

Step-by-step explanation:
Leah wrote 2 different fractions with the same denominator. Both fractions were less than 1.
1. Can their sum equal 1?
Let Leah fractions be 
and 
Both these fractions have the same denominators and are less than 1. Find their sum:
2. Can their sum be greater than 1?
Let Leah fractions be and 
. Both these fractions have the same denominators and are less than 1. Find their sum:
Assuming that:

m
=
3.3
f
t
1m=3.3ft
We can make the conversion from feet per second to meters per second with this procedure:
(
165
f
t
s
)
(
1
m
3.3
f
t
)
=
50

s
(165

ft
)(
3.3 ft
1 m
)=50
s
m
Let
x
x be the amount of meters the parachutist will fall during 15 seconds of free fall
Having that in 1 second the parachutist falls 50 meters, we can calculate
x
x :
x
=
(
50

)
(
15

)
x=(50

m
)(15 s)
x=750 m
