add all assets then add all liabilities
if assets is higher she has a positive net worth of the difference
if liabilities is higher she has a negative net worth of the difference
2t + 3j = 14 ....multiply by -3
6t + 5j = 28
--------------
-6t - 9j = - 42 (result of multiplying by -3)
6t + 5j = 28
------------add
-4j = - 14
j = -14/-4
j = 3.50
2t + 3j = 14
2t + 3(3.50) = 14
2t + 10.50 = 14
2t = 14 - 10.50
2t = 3.50
t = 3.50/2
t = 1.75
so the trail mix (t) costs 1.75 per lb and the jellybeans (j) costs 3.50 per lb
Bill $10
Tip at 25% is $2.50
Total before tax is $12.50
If you're looking for a word problem here's one,
Nichole has $8.50 and she decides to invest it in to a company worth $1,000,000 in a year the company is worth $8,000,000 as the company went up in value so did Nichole's investment, how much was Nichole's Investment worth at the end of that year?
If your'e looking for someone to show the math here's that,
if you take the decimal first and multiply that by 8 you get 4 because 0.5*8=4, then you multiply the whole number and get 64 because 8*8=64, add the two together and you get 68, 64+4=68
So area is 168 sq ft
That means that length * width = 168 sq ft
Since length = 10 + 2 w
we get (10+2w)(w) = 168
Multiply it out and you get 2w^2 + 10w - 168 = 0
This is a quadratic equation. You can use the formula here, but i'll just tell you the answer
w = -12, or 7
since it can't equal -12 (ever heard of a barn with a length of -12?), you figure out the answer is 7.
If the width is 7, then the length is 10+2(7) = 24.
Have a nice day!
