In a small town, there are 4 times as many left-handed males as there are left-handed females, and there are 3 times as many rig

horrorfan [7]

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

Rufina [12.5K]

Answer: $ 532

Step-by-step explanation:

Given: Ramona works in a clothing store where she earns a base salary of $140 per day plus 14% of her daily sales.

She sold $600 in clothing on Saturday and $1200 in clothing on Sunday.

To find : Earning in two days.

Total sales she did in 2 days = $600+$1200 = $1800

Then, her total earning for 2 days = 2 x( Base salary)+ 14% of (Total sales)

= 2 x ($140) + (0.14) ($1800)

= $(280+252)

= $ 532

Hence, she earned $ 532 over the 2 days.

The sum of 2 numbers is 50. The sum of 1/4 of the first number and 2/3 of the second number is 25.What are the numbers?

tino4ka555 [31]

Answer:

First number: 20

Second number: 30

Step-by-step explanation:

First#: x

Second#: y

Constraints:

x + y = 50

1/4x + 2/3y = 25

Isolate variable y:

x + y = 50

-1/4 (x + y = 50 )

-1/4x - 1/4y = -12.5

Add equations the two equations to eliminate x:

-1/4x - 1/4y = -12.5

1/4x + 2/3y = 25

_________________

5/12y = 12.5

5y = 150

y = 30

Substitution to find x:

x + y = 50

x + 30 = 50

x = 20
