You would have to write an equation. I would use the equation 4y=200. Thats your answer for (a). Then reverse the equation and solve to figure out the answer to (b). What we do to one side we do to other, right? So we would divide each side by 4. That leaves us with y=50. There's your answer to (b). Now to find Xavier's age we would simply do Yvonne's age minus 7. 50-7=43. There's your answer to (c).
A) 4y=200
B) 50 years old
C) 43 years old
Hope this helps!!!!

Item 9 a flight averages 460 miles per hour. the return flight averages 500 miles per hour due to a tailwind. the total flying t
Ksenya-84 [330]

Let us say that the variables for flight is designated by 1, while the return flight by 2, since the distance travelled are equal, therefore:

v1 t1 = v2 t2

or

460 t1 = 500 t2

 

Since t1 + t2 = 4.8, therefore: t1 = 4.8 – t2

460 (4.8 – t2) = 500 t2

2208 – 460 t2 = 500 t2

960 t2 = 2208

t2 = 2.3

 

t1= 4.8 – t2 = 4.8 – 2.3

t1 = 2.5

 

Answer:

The flight took 2.5 hours while the return flight took 2.3 hours.

Which expression is equivalent to g^−m ÷ g^n
WINSTONCH [101]
G^−m ÷ g^n

1st g^−m=1/g^m, hence g^−m ÷ g^n = (1/g^m) /(g^n)==> 1/(g^m)(g^(n)
==> 1/(g^m+n) or g^(-m-n)
