1. 2a=9b first we will divide the both sides with parameter b and get
2(a/b)=9 now we will divide both sides with number 2 and get
a/b=9/2 => a : b = 9 : 2
2. 6a-3b=5b first we will add to both sides number (+3) and get
6a=5b+3b => 6a=8b then divide the both sides with parameter b and get
6(a/b)=8 now we will divide the both sides with number 6 and get
a/b=8/6 if we simplify the fraction we get
a/b=4/3 => a : b = 4 : 3
3. a+b=3b we will add to the both sides parameter (-b) and get
a=3b-b => a=2b then divide the both sides with parameter b and get
a/b=2 => a/b=2/1 => a : b = 2 : 1
4. a/5=b/7 first we will divide the both sides with paremeter b and get
a/(5b)=1/7 now we will multiply the both sides with number 5 and get
a/b=5/7 => a : b = 5 : 7
Good luck!!!
Your 71,1482 doesn't make sense. But regardless,
let x = the other car's cost.
You know the total spent and the cost of one car. So logically, if you subtract the two you'd get the price of the second car.
You can do $38,295 + c = $71,1482.
Or $71,1482 - $38,295 = c.
Hey can I have brainlyist I only need one more :)
Answer:
(B) -25/4
Step-by-step explanation:
-5/3 ÷ 4/15
Copy dot flip
-5/3 * 15/4
Rewriting for easier math
-5/4 * 15/3
-5/4 * 5
-25/4
