x = 35.

Step-by-step explanation:

Co-interior angles sum up to 180°:

(2x + 43) + (2x - 3) = 180°

4x + 40° = 180°

4x = 180° - 40°

4x = 140°

x = 35°.

3/4 ÷ 3/4

step-by-step explanation:

basically divide any proper fraction with itself to fit the criteria.

so if we are using 3/4, then:

3/4 ÷ 3/4 = 1

so 1 is the quotient.

and the numerators for both these fractions is 3.   and if we divide the numerators:

3 ÷ 3 = 1

we see that quotient is equal to our original quotient as well.
