This ratio can be written as 8x+5x =390
Add the variables
13x = 390
Divide by 13 to get the value of x
390/13 = 30
Answer:
$5093.37
Step-by-step explanation:
To get Rebecca's available credit we need to take all of her payments and purchases and previous balance.
Previous balance = $398.64
Purchases = $1,257.99
Payment = $250
Credit Line = $6,500
Now first we add together her purchases and previous balance.
398.64 + 1,257.99
This will give us:
$1,656.63 Total deductions.
Now we subtract that to her credit line.
$6500.00 - $1656.63
$4843.37
Now we take her payment and add it to her credit line.
$4843.37 + $250
$5093.37
So Rebecca's available credit is $5093.37.
36(3.14) = 4/3 x 3.14 x r^3
113.04 = 4.187(r^3)
113.04/4.187 = r^3
26.997 = r^3
3√26.997 = r
r = ~3
Check: 3^3(

)(4/3) = 27(3.14)(4/3) = 113.04
Answer:
Let David's age be x years
=> James' age = x+5 years
David + James = 89
=> x + x+5=89
=> 2x=84
=> x=84/2=42 years
David's age is 42 years
