How old am I if 300 reduced by 2 times my age is 176?

it will be 125

Step-by-step explanation:

You are 62 years old.

Step-by-step explanation:

300 - 2x = 176

-300          -300

-2x = -124

/-2      /-2

x = 62

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
