Josie and her brother, Sean both have a job after school. For every $5.50 that Josie earns, her brother earns $6.50. On Tuesday, they earned $30.00. How much money did Josie earn? How much did her brother earn?

The amount earned by Josie was $13.75 and the amount earned by her brother was $16.25

Step-by-step explanation:

Let

x ----> amount earned by Josie

y ---> amount earned by her brother

we know that

------> equation A

-----> equation B

Solve the system by substitution

Substitute equation A in equation B

solve for y

Find the value of x

therefore

The amount earned by Josie was $13.75 and the amount earned by her brother was $16.25

6 on both sides and twelve on the top and the bottom

step-by-step explanation:

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
