7(x+4)-2[x-3(5+x)]=⅔(x-6)​

Mathematics
1 answer:
aev [14]3 years ago
6 0

Answer:

7(x+4)-2/3 (x-6) < 2[x-3(x+5)]

Do it 1 step at a time.

7(x+4)-2/3 (x-6) < 2[x-3x-15]

7x+28 - 2/3 (x-6) < 2[x-3x-15]

I'll assume you mean (2/3)*x-6)

---

7x+28 - (2x/3) - 4 < 2[-2x-15]

7x+24 - (2x/3) < -4x-30

Add 4x

11x+24 - (2x/3) < -30

Add 30

11x + 54 - (2x/3) < 0

Multiply thru by 3

33x + 162 - 2x < 0

31x < 162

x < 162/31

Pablo, Sofia, and Mia got some candy eggs at a party. Pablo had three times as many eggs as Sofia, and Sofia had twice as many e
andrezito [222]
Pablo : 3(2x) = 6x
Sofia :  2x
Mia : x 

Assuming x = 10
Mia : x = 10
Sofia : 2x = 2(10) = 20
Pablo : 3(2x) = 3(20) = 60

10 + 20 + 60 = 90
90/3 = 30 candy eggs per person

Pablo: 60 x 1/2 = 30
Sophia: 30-20 = 10  : 10
Mia : 30 - 10 = 20 : 20

Ratio of eggs given to sophia from pablo's set = 10/60 = 1/6
Ratio of eggs given to mia from pablo's set = 20/60 = 2/6 = 1/3

In a recent​ poll, 44​% of survey respondents said​ that, if they only had one​ child, they would prefer the child to be a boy.
viva [34]

Answer:

a) The probability that 71 of 150 will prefer boy child is 71/150 or 0.47

b) The result contradicts the poll actual percentage is 47.33% which is 3.33% more than the poll predicted

Step-by-step explanation:

If 71 out of 150 prefer boy child

The probability that the 71 will prefer boy child is

= 71/150

The actual percentage is

(71/150)*100%

= 47.33%

This contradicts the poll as this is more than the poll predicted. That means Less than 71 of 150 actually preferred boy child.
