2x = 10√3
=> x = 10√3 / 2
=> x = 5√3
hence missing side of triangle is 5√3
7h + 6b = 35.50
5h + 6b = 30.50
The difference between the 2 totals spent is $5, and there were the same number of burgers, but 2 fewer hotdogs. So $5/2 = $2.50, the cost of a hot dog. Substitute that into the equations to solve for burgers (b)
5(2.50) + 6b = 30.50
12.50 + 6b = 30.50
6b = 18
b = 3
Check the work:
7(2.50) + 6(3) =
17.50 + 18 = 35.50
Answer:$9504.80
Step-by-step explanation:
Every year, we have an increase of 9% interest. After two years, we will have 8000 * 1.09 ^2 = $9504.80
Answer:
8
Step-by-step explanation:
To solve this, you can add 2/5 b to both sides of the equation. You now have 3 + 5/5 (or 1) b = 11. => 3 + b = 11 => Now, subtract 3 from both sides, and you have b = 11 - 3, and then b = 8.
I^2 is negative 1, but I see you have a negative sign there. So it is -(-1), which is 1.
