Last week she worked 12 hours as a carpenter

earning 12x dollars

and 20 hours as a blacksmith

earning 20y dollars

and earned a total of $860

and those two things add up to 860.

Do the same with the other sentence, giving you a second equation.

12 grapes cost 90 $how many can bought in 40$
likoan [24]

Let x = the amount of grapes that can be bought for 0.40.


Note: By 90 I assume you mean 90 cents. The same for 40.


12/x = 0.90/0.40


0.90x = 12(0.40)


0.90x = 4.80


x = 4.80 ÷ 0.90


x = 5.33333


We can round the decimal to the ones place to get 5 grapes.

\large \mathfrak{Solution : }

let's solve for x :

  • \dfrac{2}{9} x -  \dfrac{1}{3}  =  - 1

  • \dfrac{2}{9}  x =  - 1 +  \dfrac{1}{3}

  • \dfrac{2}{9} x =  \dfrac{ - 3 + 1}{3}

  • x =  \dfrac{ - 2}{3}  \times  \dfrac{9}{2}

  • x =  - 3

I hope it helped...

Six hundred paving stones were examined for cracks, and 15 were found to be cracked. The same 600 stones were then examined for
9966 [12]

Answer: 0.01

Step-by-step explanation:

Let the events are :

C = paving stones found to be cracked.

D = paving stones found to be discolored.

Given : Total stones : T = 600  (i)

C = 15

D=  27

C'∩D'=  564   (ii)

Since C'∩D' = (C∪D)' = T- C∪D         (iii)

From (i) , (ii)and (ii) , we have

564 = 600- C∪D

⇒ C∪D=600- 564= 36

Formula : C∩D= C+D- C∪D

Put values , we get

C∩D= 15+27-36=6

Now ,

P(C\cap D)=\dfrac{C\cap D}{T}=\dfrac{6}{600}=0.01

The probability that it is both cracked and distorted is 0.01.
