Answer:
3(x - 10)
Step-by-step explanation:
3x - 30 = 3(x - 10)
I'll assume the above equation is: 9 - 7x = 7 - 4(2x+3)
* do distributive multiplication
9 - 7x = 7 - 8x - 12
*move like terms
-7x + 8x = 7 - 12 - 9
* solve for x
x = 7 - 21
x = -14
To check, substitute x by its value -14
9 - 7x = 7 - 4(2x+3)
9 - 7(-14) = 7 -4[2(-14) + 3]
9 + 98 = 7 - 4(-28 +3)
107 = 7 - 4(-25)
107 = 7 + 100
107 = 107
Answer:
$48.54
Explanation:
We must express the interest rate on a monthly basis.
i = 8 %/yr = 0.6667 %/mo = 0.006 667
A = $4000
n = 120 mo





P = 48.531
The banks round up the numbers, so Seki’s monthly payment is $48.54.
