Aproblem states: "there are 7 more girls than boys in a class. there are 23 students in the class in all. how many girls are there in the class? " what are the unknowns in this problem? a. the number of boys and the number of girls in the class b. the number of boys in the class c. the number of students in the class d. the number of girls in the class

The unknowns in this problem are A. The number of boys and the number of girls in the class.

We know there are 7 more girls than boys, but because we don't know how many boys there are, we don't know how many girls there are.

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

answer: answer is c!

ok i got to organize the

3/15 and 12/55

3*

aha

3*4 equals 12 but not

a: no

b:

8/24 12/35

no

gautie

it's c

5/18 = 25/90

5*5=25

18*5 = 90

hope that you!

one more happy customer!
