stefan is three years younger than his sister katie. The sum of Stefans age three years ago and 2/3 of katies age at that time i

sammy [17]

If x is the age of S

And y is the age of K

So we have x=y+3

And the second equation is x-3 + 2/3)y = 12

We have to solve the system

x-y=3

x+2/3y=15

we find x=10.2 and y=7.2

so Katie is 7

Using complete sentences, write an indirect proof proving that if x=30, then 3/4x+5≠20 (3/4 being three over four)

WARRIOR [948]

hypothesis :-
if x=30, then 3/4x+5≠20
let Q:- x=30 P:- 3/4x+5≠20
we need to prove if Q then P (Q →P)

proof :-
lets assume 34x+5=20 is true
now x=30
so
3/4(30)+5=27.5 ≠20
which is a contradiction

The distance between the baseball stadium and the airport is 1.6×10^6 centimeters.Which unit of measurement is most appropriate

Ad libitum [116K]

Answer:

'Kilometers' is the most appropriate unit to measure this distance. 

Step-by-step explanation:

The distance between the baseball stadium and the airport is $1.6\times 10^6$ centimeters.

$(1.6\times 10^6)cm = (16\times 10^5)cm$

Now, 10⁵ centimeters is equal to 1 kilometer.

That means, $(16\times 10^5)cm = (16\times 1)km= 16 km$

So, 'Kilometers' is the most appropriate unit to measure this distance.
