Answer:
32 one-dollar bills.
Step-by-step explanation:
Let <em>x </em>represent one-dollar bills and <em>y </em>represent two-dollar bills.
He has a total of 49 bills. Therefore:

The total amount of money James has is 66. <em>x</em> is worth one dollar, while <em>y</em> is worth two dollars. Therefore:

We have a system of equations. Solve by substitution:

Therefore, James has 32 one-dollar bills and 17 two-dollar bills.

Answer:

Step-by-step explanation:
See the attached bar graph.
The bar graph shows the numbers of reserved campsites at a campground for one week.
So, on Friday and Saturday, the total number of reserved campsites will be (26 + 30) = 56.
Now, the total number of reserved campsites from Monday to Sunday is (5 + 3 + 4 + 7 + 26 + 30 + 9) = 84.
Therefore, the percent of the reservations on Friday and Saturday will be

Answer:
Step-by-step explanation:
hello :
100+(n-2)² = 149
100-100+(n-2)² = 149-100
(n-2)² = 49
(n-2)² - 49 =0 but 49=7²
(n-2)² - 7² =0 use identity : a²-b²=(a-b)(a+b)
(n-2-7)(n-2+7)=0
(n-9)(n+5)=0
n-9=0 or n+5=0
n=9 or n=-5
