Responda: Por favor, é urgente.
kumpel [21]

Answer:

C) CA=40

Step-by-step explanation:

2y/(2y+4)=(2y+6)/4y

cross multiply

8y²=4y²+20y+24

4(2y²)=4(y²+5y+6)

divide both sides by 4

2y²=y²+5y+6

y²-5y-6=0

(y-6)(y+1)=0

So the answer must be either 6 or -1.  Since it can't be a negative number, it must be 6.

CA=2(6)+4+4(6)

CA=12+4+24

CA=40

Drake wants to save $750 so that he can take a class on computer analysis for cars. The class is being held on various dates ove
allochka39001 [22]
<span>Drake can meet his $750 planned savings goal with either concept. After 4 weeks, he was $30 less than where he planned to be ($450 instead of $480). If he simply added $250 after two more weeks, he would be at $720 instead of $750, and would have to wait one more week to take the class. Conversely, if he added $15 to the next two weeks' savings, he would recoup the $30 he pulled out of the savings in those two weeks and would be back on the path to being able to take the course at the end of the 6-week period as originally planned.</span>
