Maria bought 3 1/10 kilograms of apples. The apples she bought were green and red. The weight of the green apples was 1 4/10 kilograms. Find the weight of the red apples.

1 & 7/10

Step-by-step explanation:

put both fractions in improper form. you'll get 31/10 and 17/10. because both fractions have same denominator you don't have any extra steps and you can subtract them. you'll get 17/10. change this back to mixed form.

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
