Answer:
Savannah's age = 6 years
Step-by-step explanation:
Let
Savannah's age = x
Dylan's age = 15
Dylan is 15, which is 3 years older than twice his sister Savannah’s age
Dylan = 2x + 3
Find Savannah's age
2x + 3 = 15
Subtract 3 from both sides
2x + 3 - 3 = 15 - 3
2x = 12
Divide both sides by 2
2x / 2 = 12 / 2
x = 6
Therefore,
Savannah's age = x
= 6 years
Dylan's age = 2x +3
= 2*6 + 3
= 12 + 3
= 15 years
14/15 - 5/12
Common denominator is 60.
56/60 - 25/60
= 31/60 as fraction.
= 0.516 as decimal.
Answer:
5
Step-by-step explanation:
The two numbers are <u>12 and 51.</u>
<h3>
EXPLANATION</h3>
To solve this, I did 63-15, to get 48.
I then divided this by 4, to get the first number, which is <u>12.</u>
To find the second answer, I multiplied 12 by 3, which is 36, and then added the 15 back on, to get <u>51.</u>
<u>51 + 12 = </u><em><u>63</u></em>
