The system of linear equations that may be used in order to solve this problem is as follows:
x + y = 37
2x + 3y = 95
This is considering that x is the number of bracelets sold and y is the number of necklaces.
The values of x and y in the equation are 16 and 31, respectively.
Thus, the answer is 16 bracelets and 21 necklaces.
Answer:
Joanna bought 21 items that come out to a total of $33.33. She bought 9 notebooks and 12 pencils.
Step-by-step explanation:
Notebooks (N) = $1.85 Pencils (P) = $1.39
9N+12P= $33.33
9*1.85=16.65
12*1.39=16.68
16.65+16.68=33.33
Answer:
No
Step-by-step explanation:
Jack read 2/6 or 1/3. Sue read 2/3, twice as much.
It looks like ∆ is defined as
<em>a</em> ∆ <em>b</em> = (<em>a</em> + <em>b</em>)² + 5
If that's the case, then
1 ∆ (-4) = (1 + (-4))² + 5 = (-3)² + 5 = 9 + 5 = 14
