Sos i need i'm not good at math just reading and !

I got 45 for x and 135 for z.

X and 3x are supplementary (they equal 180) x+3x=180 — 45+3(45)=180

Then x and z are also supplementary x+z=180 — 45+z=180

(45-45)+z=180-45

Z=135

Sorry if this is wrong. I did my best, hope it helps

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.

the answer is b.)

< 1=< 2
