Question

If A+B = 76. & A -B = 38. What is A/B?

Answer 1

line 1: a+b=76

line 2: a-b=38

line 1+ line2...2a=114

so a=57

from line 1, b=76-a=76-57=19

thus, a/b=57/19=3

Answer 2

a+b=76

a-b=38

a/b=?

a=57.b=19

how it get means.............

a=57,b=19 then

a/b=57/19=3

why means a=57 and b=19 satiefy the all the above conditions

Answer 3

Solution:-

A=57

B=19

A+B=76

A-B=19

A/B=3

Answer 4

If  "A"and "B" together equal 76 ... and "A" minus "B" equal "38". Then it should be agreed that both "A" and "B" equal "38" each. If "38" is divided by "38" then the answer has to be "ONE".

Comments

if a = 38 and b = 38
then a(38) - b(38) would be 0  not 38 ;)

Answer 5

A = 57

B = 19

57+ 19=76

57-19=38

57/19=3  answer is 3

Answer 6

line 1: a+b=76 line 2: a-b=38 line 1+ line2...2a=114 so a=57 from line 1, b=76-a=76-57=19 thus, a/b=57/19=3

Answer 7

A is 17

B is 19

57+19=76 ; 57-19=38 ; 57/19 = 3

Answer 8

A+B=76 & A-B=38 ⇒ A+B+A-B = 76+38 ⇒ 2A=115 ⇒ A=57

A=57 ⇒ 57+B=76 ⇒ B=19
           ⇒ 57-B=38 ⇒ B=19

A/B ⇒ 57/19=3

Answer 9

a+b=76

 a-b=38

Add

2a=114

a=57

b=76-a=76-57=19

a/b=57/19=3

Answer 10

a+b=76,a-b=38,a/b=?

Answer 11

non-mathmatical way

If

76 - 38 = 38

38 / 2 = 19

then

B = 19
 

A = 76 - 19 = 57

 

57 / 19 = 3

Answer 12

76 is 100% of a+b, 38 is 50% of 76. analysis A-B= 50%,75% - 25% = 50%. A=57, B=19, answer is 3.

Answer 13

a + b = 2a - 2b 3b = a a/b = 3

Answer 14

A+B=76, A-B=38

A=76-B

76-B-B=38

-2B=38-76

-2B=-38

B=19

A=76-19=57

A/B=57/19=3

Answer 15

a+b if a-b=5, ab=36

Answer 16

A + B = 76
A - B = 38

JUST ADD

2A = 114

A = 57
B = 19

A / B = 57/19 = 3 ANSWER

Answer 17

A = 76 -B

76 -B -B = 38

-2B = -38

B = -38 / (-2)

B= 19

A + 19 = 76

A = 76 - 19

A = 57 --------------> Now: A/B = 57/19 = 3

Answer 18

A+B=76

A-B=38

2A=114

A=114/2

A=57

B=19

Answer 19

(A+B)x(A-B)=76x38=2888

A power 2-b power 2=2888

A2=76x76=3249

B2=38x38=361

a2-b2=3249-361=2888

root 3249 =57

r00t 361 =19

A divide B =57 over 19 =3

Answer 20

A+B=76 A-B=38 B=76-A B=A-38 76-A=A-38 114=2A A=114/2 A=57 B=57-38 B=19 A/B=57/19=3

Answer 21

• A+B = 76 
  Add 
  A-B = 38 
  A+B+A-B = 114 
  2A = 114 
  A = 57 
  
  A+B - A-B = 38 
  2B = 38 
  B =19 
  
  A/B = 57/19 = 3

Answer 22

A+B=76 & A-B=38 it's mean A=38 & B =38 so A÷B=38÷38=1

Answer 23

A+B=C A+B=76 38+38=76 A-B=C A-B=38 76-38=38 A/B=C A/B=19 114/6=19 final answer A+=38, A-=76, A/=114 C+=76, C-=38, C/= 19 B+=38, B-=38, B/=? A/B=C 114/B=19 114=B*19 114/19=B B=114/19 B=6 answer previous

Answer 24

Let's Suppose
A+B=76 ---- (i)
A-B=38 ----(ii)
Now Add (i) + (ii)
2A=114
Then A=57
Now we'll put value of A in Eqaution (i) or (ii)
We'll get Answer for B! i.e
57+B=76
B=76-57
B= 19
Now We have value of Both Parameters A & B
A/B=?
57/19
So A/B = 3
 

Answer 25

A+B=76 , A-B=38

2A=76

A=57

Same

2B=38

B=19

SO,

A/B=57/19=3

A/B=3

Answer 26

A + B = 76; A - B = 38; A/B =? A+B - (A-B) = 76 - 38 A+B -A+B = 38 2B = 38 If B = 19, then A = 57 ... therefore; A/B = 3

Answer 27

My answer is 3 76/2=38 76/4=19 57+19=76 57-19=38 57/19=3
