Answer:
Step-by-step explanation:
the current ages:
father= 32 yrs old
son=5 yrs old
-------
4(5+x) = 32+x
20+4x = 32+x
4x-x = 32–20
3x =12
x = 12/3
x = 4 years
------------------------------------
after the 4 years later the farther age will be 36 ( 32+4 = 36)
the son will be 9 ( 5+4= 9 years)
the x presents how the father will be after 4 times the age of the son
48÷7= 6.85
That would be your answer
Answer:
$39.90
Step-by-step explanation:
if each video game cost $3.30, and she rented 7, then you multiply $3.30 by 7, to get $21.10, and if each DVD was $4.20, and she rented 4, then its $4.20x4= $16.80
after that you just add the two total costs together, which is $23.10+$16.80=$39.90

Answer: $611</h3>
Work Shown:
30% of 470 = 0.30*470 = 141
The value goes up by $141, so the answer would be 470+141 = $611
A slight shortcut would be to say
1.30*470 = 611
This works because 1.30 = 1 + 0.30 = 100% + 30%
