" b) "-5<=(2-3x)/(4)<=9

If a :b =3:5 find 2a +3b: 4a+5b

If [(a+b,2),( 5,b)]=[(6, 5),( 2, 2)] , then find adot

If a:b=2:5backslash then the value of (2a+3b):(7a+5b) is 5:3 b.6:5 c.12:5d .30:19

Simplify ( 4.5 a + 1.5 b ) ^(2) + ( 4. 5b + 1. 5a ) ^(2)

If b/a = 3/5 then (3a-5b)/(3a+5b) = ?

If cos(A-B)=(3)/(5) and tan A tan B=2,thencos A cos B=(1)/(5) b.cot cos B=-(1)/(5)cs in As in B=-(1)/(5)ds in As in B=-(1)/(5)

If a:b=2:5 then (3a+4b):(4a+5b)=

Prove that: |[a+3b, a+5b, a+7b],[a+4b, a+6b, a+8b], [a+5b, a+7b, a+9b]|= 0

3a+5b=26;a+5b=22

3a+5b=26;a+5b=22
