Question

1) If a number is doubled, it gives the same result as 24 is subtract from it. Find the number.
2) P = 2πr . Calculate (P) when r= 10
3) Y= 2x -6 . Find y when x=10.

ps:if u give a proper answer and not nonsense I will mark you as brainliest

Answer 1

Answer:

plsss folow me.

Step-by-step explanation:

1) let the number be x

so 2x

let the number equal to 0

=> 2x-24=0

=> x = 12

thus , the number is 12.

2) Given : r= 10

acc to the Question:

P =2πr

= 2×22/7×10

= 62.85

so, the value of P is 62.85

3) Given, x= 10

Y= 2x-6

Y = 2(10)-6

= 20-6

Y = 14

therefore , the value of y us 14.

Answer 2

Answer:

1. 0

2. 62.8

3. 14

Step-by-step explanation:

1. I think that your question is not clear, but I think it should be 0 as ( 2×0 )-24= (-24) and 0-24= (-24)

2. P = 2πr. , radius = 10

P = 2×3.14×10. ( π value is approx 3.14 or 22/7 )

P = 62.8

3. Y = 2x-6. , x value is equal to 10

so,

Y = 2×10-6

Y = 20-6

Y = 14
