Mathematics

SOVA2 [1]3 years ago
7 0
1. create an equation --- 101 = n+15+3n
2. simplify (combine like terms) --- 101= 4n+15
3. subtract 15 from both sides (101-15 = 4n+15-15) --- 86=4n
4. divide both sides by 4 (86/4=4n/4) --- 21.5 = n


therefor, n = 21.5 

to check the equation just plug in 21.5 for n and it should equal 101

krek1111 [17]

Answer:

Step-by-step explanation:

these are two different questions .

first i solve first

position of submarine= -250/3 meters below see level

height descended=120 % of 250/3=120/100 ×(250/3)=300,00/300=100 m

new location=-250/3+(-100)=-650/3 below see level.

2nd question

position of submarine=-250 2/3=-752/3 m below see level

height descended=120 5/8=965/8 m =-965/8 m below see level

new positin=-752/3+(-965/8)=-(6016+2895)/24=-8911/24=-371 7/24m below sesa level.

An inverse proportion has the equation ...

  y = k(1/x) . . . . k is the constant of proportionality

__

Solving for k, we find ...

  k = xy

The coordinates of the given point can be used to find k:

  k = (3)(5) = 15
