please give answers ​

Answer 1

Answer:

Q2.(A)

1.

x+8×5=50

2.

-1 and 1

3.

The rational numbers between any 2 number a and b are infinite.

4.

Step 1.

Given:2y-8/5 = 2/5

=(y×2 ) - 8/5 = 2/5

Step 2.

by tranposition method, take -8/5 to the r.h.s of the equation and make it +8/5.

= y×2 = 2/5 + 8/5

= y×2= 10/5

= y×2= 2

Step 3.

By transposition method, take ×2 to the r.h.s of the equation and make it ÷2.

=y = 2÷2

=y = 1

Therefore y=1 is the solution to this equation.
