√169= 13
169-13 = 156
156 - 37 = 119

Your answer:
Divide 48 by 0.6 for the answer.
The answer is 80.
So she has 396460
she will withdarw 1700 per month, and withdraw is loss or minus or (-)
after x months, she has 359060 left so
total-withdrawn=remaining
withdrawwn=1700 times months so withdrawn=1700x
total-1700x=remaining
total=396460
reaining=359060
subsitute
isolate x then divide is the strategy
396460-1700x=359060
add 1700x to both sides
396460=359060+1700x
subtract 359060 from both sides
37400=1700x
divide both sides by 1700
22=x
she has been retired for 22 months
Answer:
y = 175. x = 300. Disney vacation is 300 sold. Cars sold were 175.
Step-by-step explanation:
They want to raise $80,000. There are a total of 475 tickets.
150x + 200y (Disney Vacation + Win a car) = 80,000
x + y = 475.
__
y=475-x
150x+200(475-x)=80000
150x+95,000-200x=80,000.
-50x + 95,000 = 80,000.
-50x = -15,000
x = 300.
Disney vacation is 300 sold.
300 + y = 475.
y = 175.
Cars sold were 175.
Additional Info:
I am 14 years old and I'm learning solving the systems by elimination and substitution, etc. Hope this is the correct answer.
