Cecilio tiene "x" años y Jonathan tiene "y" años.
Tres veces la edad de Cecilio es 3x y 3x es 48 años mas que "y".
3x = y + 48
Jonathan tiene un tercio de la edad the Cecilio.
y = x/3
3x = y + 48 se sustituye x/3 por y
3x = x/3 + 48
3x - x/3 = 48
9x/3 - x/3 = 48
8x/3 = 48
x = 48 * 3/8
x = 18
Cecilio tiene 18 años.
y = x/3 = 18/3 = 6
Jonathan tiene 6 años.
a=18 , d =?10,n,=12
I hope this is the answer
Answer:
Step-by-step explanation:
The rent will increase 11 times before the 12th year
<u>Required equation:</u>
- $1700*(1 + 0.09)^11 = $4386.70 (rounded)
The answer is D you would multiply the 18 by the eight then multiply it by .2 and the you multiply by the 1/4.
Answer: 3 and 12
<u>Step-by-step explanation:</u>
Let x represent one of the numbers and y represent the other number. Then,
Sum: x + y = 15 → y = 15 - x
Product: xy = 36
Use substitution method by replacing "y" with "15 - x" in the second equation, then solve for x:
x(15 - x) = 36
15x - x² = 36
0 = x² - 15x + 36
0 = (x - 3)(x - 12)
0 = x - 3 and 0 = x - 12
x = 3 x = 12
