ht-handed females as there are right-handed males. There are a total of 204 males and 348 females in the town.
Let x represent the number of left-handed females, and let y represent the number of right-handed males. Write a system of equations to represent the situation. What is the value of x, the number of left-handed females?

Answer:

  (b)  24

Step-by-step explanation:

The given variable definitions and the given relationships let us write these statements:

  LH males = 4 × LH females = 4x

  RH females = 3 × RH males = 3y

  LH males + RH males = 204 = 4x +y

  RH females + LH females = 348 = 3y +x

Your favorite method of solving equations of this sort can tell you ...

  (x, y) = (24, 108)

There are 24 left-handed females.

__

<em>Additional comment</em>

Other numbers involved here are ...

  y = 108 . . . . right-handed males

  204-108 = 96 . . . . left-handed males (=4×24)

  348-24 = 324 . . . . right-handed females (=3×108)

__

If you want to solve the equations by hand, you can use substitution for y to get an equation in x:

  3(204 -4x) +x = 348   ⇒   -11x = -264   ⇒   x = 24

Frank’s bookshelf is 112 meters high. Each row in the bookshelf is 316 meters high. How many rows are there in Frank’s bookshelf
kykrilka [37]
This makes no sense because the rows have to be smaller than the bookshelf
the rows fit in the bookshelf

the way to do it would be height of bookshelf/height per row=number of rows (round down)
if we used that, then 112/316=0.35 rows
round down
0
so we got 0 shelves because it is impossible to have a row higher than the bookshelf that it is on
