Answer:
x=9
Step-by-step explanation:
x+1=10
*subtract 1 from both sides
x=9
Dividing 12/7 ÷ 12/7 is 1 since you arent doing anything like 12/7 ÷ 12/9
so your answer would be 1

Answer:
She paid back $192 in interest
Step-by-step explanation:
A = P(1+r)^n
P = $1,200
r = 10.5% = 0.105
n = 18 months = 18/12 = 1.5 years
A = 1,200(1+0.105)^1.5 = 1,200(1.105)^1.5 = 1,200×1.16 = 1,392
Amount = $1,392
Principal = $1,200
Interest = amount - principal = $1,392 - $1,200 = $192
Umm not really sure but I'd go with A. You may need another source to double check my answer, I'm probably wrong.
