Answer: all of the numbers that have x and the rest you can combine
Step-by-step explanation:
Answer:
n=−0.545455
Step-by-step explanation:
n(6.5)=−3+n
Simplify both sides of the equation.
n(6.5)=−3+n
6.5n=−3+n
6.5n=n−3
Subtract n from both sides.
6.5n−n=n−3−n
5.5n=−3
Divide both sides by 5.5.
5.5n
5.5
=
−3
5.5
1 hundred can also be 10 tens so when you add 10 tens and 4 tens you 14 tens and that is the same thing as 14 tens
Answer:
B
Step-by-step explanation:
Given
14 + 10y ≥ 3( y + 14) ← distribute
14 + 10y ≥ 3y + 42 ( subtract 3y from both sides )
14 + 7y ≥ 42 ( subtract 14 from both sides )
7y ≥ 28 ( divide both sides by 7 )
y ≥ 4 → B
So 1 mile per 3 minute or
1 times 20=20
3 times 20=60
20 miles in 60 minutes or
20 miles per hour
20 mph with wind
4 mins agains the wind
multiply 15
15 miles per hour agains the wind
so d=st
distances are the same
d=st
20mph with the wind
20=wind+real speed
15mph agains the wind
15=real speed-wind
20=w+rs
15=-w+rs
add together
35=2(rs)
divide 2
real speed=17.5
