Lucy purchase a swimsuit and a towel. The towel represent 30% of the total cost. If she spent $15.00 on the towel, then what was
Llana [10]

Answer:

$50

Step-by-step explanation:

Given data

Let the total purchase be x

Hence 30% of x is $15

Let us find the value of x

30/100*x= 15

0.3*x=15

0.3x=15

x= 15/0.3

x= $50

Hence the purchase is $50

What is the solution to the system of equations?
Leto [7]

Answer:

  1. (x, y) = (8, -1)
  2. (x, y) = (7, 10.5)

Step-by-step explanation:

1. You can use the expression for y to substitute into the first equation:

  2x +4(1/4x -3) = 12

  2x +x -12 = 12 . . . . . . eliminate parentheses

  3x = 24 . . . . . . . . . . . add 12; next divide by 3

  x = 8 . . . . . matches choice C

__

2. You can use the expression for y to substitute into the second equation:

  x -2(2x -3.5) = -14

  -3x +7 = -14 . . . . . . eliminate parentheses

  21 = 3x . . . . . . . . . . add 3x+14; next divide by 3

  7 = x . . . . . matches the third choice

_____

When the answer choices are sufficiently different, you only need to find one value to determine which is the correct choice. (If you want to check your work further, you can substitute the other answer value into the two equations to see if it works.)

For a certain bathtub, it takes the hot water faucet
Valentin [98]
So, we know both faucets open, can do the whole job in 6minutes

ok, how much has the faster cold water faucet done in 1minute then?

well, let's say the the rate of speed of the cold water faucet is "c", so in 1minute it has done 1/c of the whole work

now, we know the hot water faucet is slower, it takes it 3 times as long, that means is 1/3 the speed of the cold water faucet, so, how much does the hot water faucet do in 1min?   well, we know is 1/3 fast as the cold one, the cold one is 1/c, what's 1/3 of 1/c? well, 1/3 * 1/c

now, we know they both added together, can do the whole job in 6 minutes, so in 1minute, they've done 1/6 of the job then

thus

\bf \begin{array}{cccccclllllll}&#10;\cfrac{1}{c}&+&\left( \cfrac{1}{3}\cdot \cfrac{1}{c} \right)&=&\cfrac{1}{6}\\\\&#10;\cfrac{1}{c}&+&\cfrac{1}{3c}&=&\cfrac{1}{6}\\\\&#10;\uparrow &&\uparrow &&\uparrow \\&#10;\textit{cold water rate}&&\textit{hot water rate}&&\textit{total done by both}&#10;\end{array}\\\\&#10;-----------------------------\\\\

\bf \cfrac{3+1}{3c}=\cfrac{1}{6}\implies 24=3c\implies \cfrac{24}{3}=c\implies \boxed{8=c}&#10;\\\\\\&#10;\textit{now, if the cold water faucet can do it in 8 minutes by itself}\\\\&#10;\textit{then the hot water faucet can do it in 3 times as long}&#10;\\\\\\&#10;3\cdot 8\implies \boxed{24}
