Answer:
u= -3 v=11
Step-by-step explanation:
7u+2v=1 17u+6v=-9
-3(7u+2v=1)= -21u-6v=-3
-21u-6v=-3 + 17u+6v=-9 = -4u= -12
u=-3
7(-3)+2v=1
-21+2v=1
2v=22
v=11
The answer is D.
1 sq ft = 1 ft x 1 ft
= 12 in x 12 in
1 sq ft = 144 sq in
5 sq ft = 144 * 5 = 720 sq in.
Answer: 1.25n
=======================================================
Explanation:
Erica sells bracelets for $2 each. If she makes and sells n of them, then she gets 2n dollars of revenue.
Making n bracelets cost her a total of 0.75n dollars because each bracelet costs 0.75 dollars, or 75 cents.
Subtract the revenue and cost to get the profit
profit = revenue - cost
profit = 2n - 0.75n
profit = (2-0.75)n
profit = 1.25n
The expression 1.25n means that she earns $1.25 in profit per bracelet sold.
