Answer» ANSWER: Step-by-step explanation: 65=13X5 --> only combination a+b+ab=65 b(a/b+1+a)=13X5 if b=5--> 5(a/5+a+1)=65 a/5 +1+a= 13 6a+5=65 6a=60 a=10, b=5 a-b=5

2.

if a and b are positive integers then a+b+ab=65 , find (a-b) . [a,b

Answer»

ANSWER:

Step-by-step explanation:

65=13X5 --> only combination

a+b+ab=65

20 consecutive number starting from 100

Answer»

ANSWER: i got only 25 of them

Step-by-step explanation:

Let X= the FIRST consecutive number

Let x+1= the second consecutive number

Let x+2= the third consecutive number

Let x+3= the fourth consecutive number

Let x+4= the fifth consecutive number

[x+(x+1)+(x+2)+(x+3)+(x+4)]/5=100 [Given]

[5x+10]/5=100 [Combine like terms]

5x+10=500 [Multiply both sides by 5]

5x=490 [Subtract 10 from both sides]

x=98 [Divide both side by 5]

Let x=98, the first consecutive number

Let x+1=99, the second consecutive number

Let x+2=100, the third consecutive number

Let x+3=101, the fourth consecutive number

Let x+4=102, the fifth consecutive number

[100+101+102]/3=? [Given]

303/3=? [Addition]

101=? [Division]

Answer: 101 is the average of the 3 largest numbers.

Answer» Answer: 19,959 Step-by-step explanation: GIVEN : To EVAUATE : (105 × 95) + (96 × 104) SOLUTION : We KNOW that, (a + b)(a - b) = a² - b² ⇒ (105 × 95) + (96 × 104) ⇒ ( [100 + 5] × [100 - 5] ) + ( [100 - 4] × [100 + 4] ) ⇒ (100² - 5²) + (100² - 4²) ⇒ 100² + 100² - 5² - 4² ⇒ 10,000 + 10,000 - 25 - 16 ⇒ 20,000 - 41 ⇒ 19,959

Answer:

19,959

Step-by-step explanation:

GIVEN :

To EVAUATE :

(105 × 95) + (96 × 104)

SOLUTION :

We KNOW that,

(a + b)(a - b) = a² - b²

⇒ (105 × 95) + (96 × 104)

⇒ ( [100 + 5] × [100 - 5] ) + ( [100 - 4] × [100 + 4] )

⇒ (100² - 5²) + (100² - 4²)

⇒ 100² + 100² - 5² - 4²

⇒ 10,000 + 10,000 - 25 - 16

⇒ 20,000 - 41

⇒ 19,959
