Answer»

Step-by-step explanation:

17. A=2500

SI=500

P=2500-500

=2000

R=10%

So..T=SI×100/P×R

T=500×100/2000×10

Answer» Step-by-step EXPLANATION: (i) x + 3 = 0 L.H.S. = x + 3 By putting x = 3, L.H.S. = 3 + 3 = 6 ≠ R.H.S. ∴ No, the equation is not SATISFIED. (ii) x + 3 = 0 L.H.S. = x + 3 By putting x = 0, L.H.S. = 0 + 3 = 3 ≠ R.H.S. ∴ No, the equation is not satisfied. (III) x + 3 = 0 L.H.S. = x + 3 By putting x = −3, L.H.S. = − 3 + 3 = 0 = R.H.S. ∴ YES, the equation is satisfied.

SOLVE:(i) 3s =12=0 (ii) 8m-3=13 (iii) 17+3s==-4(iv)29(1-x) =-12(v)3x-7=-2(vi) – 2(x + 3) = 10

Answer»

Step-by-step EXPLANATION:

(i) x + 3 = 0

L.H.S. = x + 3

By putting x = 3,

L.H.S. = 3 + 3 = 6 ≠ R.H.S.

∴ No, the equation is not SATISFIED.

(ii) x + 3 = 0

L.H.S. = x + 3

By putting x = 0,

L.H.S. = 0 + 3 = 3 ≠ R.H.S.

∴ No, the equation is not satisfied.

(III) x + 3 = 0

L.H.S. = x + 3

By putting x = −3,

L.H.S. = − 3 + 3 = 0 = R.H.S.

∴ YES, the equation is satisfied.

18) By what number should (-6/11) be multiplied to get (-32/11)?

Answer»

Step-by-step EXPLANATION:

(-6/11) × X = ( -32/11)

x= -32/11 ÷ -6/11

the RECIPROCAL of -6/11 is 11/-6

x= -32/11× 11/-6

x=16/3
