Write a decimal for the decimal form 2 × 10 + 6 × 1 + 3 × ( 1 /100) + 9 × ( 1/ 1000)

26.039

Step-by-step explanation:

2*10+6*1+3*(1/100) + 9 * (1/1000) =

2*10+6*1+3*0.01 + 9 * (1/1000) =

2*10+6*1+3*0.01 + 9 * 0.001 =

20+6*1+3*0.01 + 9 * 0.001 =

20+6+3*0.01 + 9 * 0.001 =

20+6+0.03 + 9 * 0.001 =

20+6+0.03 +0.009 =

26+0.03 +0.009 =

26.03 +0.009 =

26.039

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer
