I don't understand how to the problem

Mathematics

Amanda [17]3 years ago

We have:

(30x²+23x+16)/(cx+3) - 13/(cx+3) = 6x+1

(30x²+23x+16 - 13)/(cx+3) = 6x+1

(30x²+23x+3)/(cx+3) = 6x+1

30x²+23x+3 = (cx+3)(6x+1)

30x²+23x+3 = 6cx²+cx+18x+3

30x² + 23x + 3 - 6cx² - cx - 18x - 3 = 0

(30 - 6c)x² +(5 - c)x = 0

6(5 - c)x² +(5 - c)x  = 0

(5 - c)(6x² +x) = 0, and x∈ R\ {3/c} ⇒ 5 - c = 0 ⇒ c = 5.

Alika [10]
Hello, in order to solve this you first need to take $20 subtracted from 160 that leaves you with 140 next because she bought 4 sweaters you need to divide your remaining cash spent by 4 to get a total of $35 a sweater.

I hope this is what you were looking for, have a great day!

AB:BD = 3:4 <br><br> AC:CD = 3:2 <br><br> Work out AB:BC:CD
Papessa [141]

Answer:

15:6:14

Step-by-step explanation:

AB:BD is split into a total of 3+4=7 parts.

AC:CD is split into a total of 3+2=5 parts.

So, if the two ratios are put on a number line together with the points A, B, C, and D, the number line would be split into a total of 35 parts (the LCM of 7 and 5).

AB would be (3/7)*35=15.

CD would be (2/5)*35=14

BC would be 35-(15+14)=6

So, the ratio is 15:6:14.
