You would do 5(9)=3x
Then get 45=3x
Divide both sides by 3
Get 15 for the answer

A plane flies at x miles per hour in still air. Flying with a tailwind, its speed is 485 miles per hour. Against the wind, its a

Svetradugi [14.3K]

Answer:20mph

Step-by-step explanation:

speed of plane = x mph

Speed of plane with wind = 485 mph

So therefore, speed of wind =

485 - x

Speed of plane against wind = 445 mph

So therefore, speed of wind =

x - 445

So therefore, equating the 2 equations of speed of wind

485 - x = x - 445

Collect like terms

485 + 445 = x + x

930 = 2x

2x = 930

x = 930/2 = 465 mph

Speed of wind = x = 465mph

So we put this value on any of the equations for speed of wind

Speed of wind = x - 445 = 465 - 445

= 20 mph

So therefore, speed of wind = 20mph

Find the missing number. 30,______ 19, 13 1/2.

Andru [333]

The answer is 24.5 because $19-13 \frac{1}{2} = 5 \frac{1}{2}$ so you add 5.5 from 19 to get the answer

Mariulka [41]

48 is 80% of 60

Divide 48 over 60:
$\frac{48}{60} = 0.8$

Convert your decimal to a percentage:
$0.8 \times 100 = 80$

$\large \mathfrak{Solution : }$

As we know :

Dividend = Divisor × Quotient ( taking remainder as 0 )

So, Quotient = Dividend ÷ Divisor

by using the above relation we can say :

q = t ÷ 23

therefore, correct option is C. t ÷ 23
