Dylan is wrong because if you multiply that ratio times 2 it would be 6/2 not 7/2.
Answer:
Step-by-step explanation:
18:12*3=4,5
5000*4,5:100=225
5000+225=5225
1$ is 100cents
45$ is 4500 cent
THE ORIGINAL price is $53
if 85% = $45
so 15%= ? cross multiply
45x15=85x$
675/85=x$
7.9 app8$ was discounted
original price=45+8=$53
in cent it is 5300 cents

Answer:
Age of Mel is 25 years.
Step-by-step explanation:
It is given that,the sum of Ali and Mel's age is 39. If Mel is 3 years younger than twice Ali's age.
Let 'x' be the Ali's age and 'y' be the Mel's age
<u>To find the value of x and y</u>
sum of Ali and Mel's age is 39
⇒ x + y = 39 ------(1)
Mel is 3 years younger than twice Ali's age
⇒ y = 2x - 3 -------(2)
⇒ 2x - y = 3 -----(3)
(1) + (3) ⇒
x + y = 39
2x - y = 3
----------------
3x = 42
x = 42/3 = 14
y = 2x - 3 = 14*2 - 3 = 25
Therefore the age of Ali = 14
Age of Mel = 25
