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

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
by
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

can u explain how u gt 57!
Solution:-

A=57

B=19

A+B=76

A-B=19

A/B=3

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".
by
if a = 38 and b = 38
then a(38) - b(38) would be 0  not 38 ;)
A = 57

B = 19

57+ 19=76

57-19=38

A is 17

B is 19

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

non-mathmatical way

If

76 - 38 = 38

38 / 2 = 19

then

B = 19

A = 76 - 19 = 57

57 / 19 = 3
by
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.
by
a + b = 2a - 2b 3b = a a/b = 3
by
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
by
a+b if a-b=5, ab=36
by
A + B = 76
A - B = 38

2A = 114

A = 57
B = 19

A / B = 57/19 = 3 ANSWER
by
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
by
A+B=76

A-B=38

2A=114

A=114/2

A=57

B=19
by
(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
by
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
by
• A+B = 76
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
by
A+B=76 & A-B=38 it's mean A=38 & B =38 so A÷B=38÷38=1
by
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

Let's Suppose
A+B=76 ---- (i)
A-B=38 ----(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

by
A+B=76 , A-B=38

2A=76

A=57

Same

2B=38

B=19

SO,

A/B=57/19=3

A/B=3
by
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
