3x =-18
X= -12
Answer:
see explanation
Step-by-step explanation:
I assume you need to find the 10% and also the amount per year maybe?
so, you will pay 21,900 dollars upfront
219000-21900=197100
219000*1/10=21900, which is ten percent.
197100=30x, x being money paid per year in this case
divide both sides by 30
6570=x
You will pay 6,570 each year for this house. You can continue to divide to find monthly payments. or quarterly payments. Divide by 12 to find monthly payment and divide by 4 to find quarterly
280 students have a total of 560 points
There 60 more boys(x+60) complete than girls(x)
2*(x+60)+2*x= 560
number of girl =x =110
girl point =110*2= 220
Answer:
x = 1.02.
Step-by-step explanation:
The x is a factor worked out from the annual interest written as a decimal fraction.
So we have 2% = 2/100 = 0.02.
The amount at the end of the first year is $100 + 0.02*100
= $100* 1.02, and in the second year it will be $100* 1.02^t where t = 2 and so on.
So we see that x in the given expression is 1.02.
