Question

Q 1-Solve 8x+5=6x-5
Q 2-Find reciprocal of (2/5)³x(5/4) ²
Q 3-∆ ABC is an isosceles with AB=AC, D is mid point of base BC ∆ABC~ ∆ADC write congruence conditions

Answer 1

Answer:

Q.1 8x+5=6x-5

=8x-6x=-5-5

= 2x=-10

=x=-10/2

=x=-5

Q.2 (2/5)3×(5/4)2

=8/125×25/16

=1/5×1/2

=2×5/5×2

=10/10

=1
