Use simultaneous equations.
let the number of bracelets be y and necklaces be z.
so
2y + 3z = 95. this is formula 1
y + z = 37. this is formula 2
so from formula 2, we can change that to
y = 37 - z. this is formula 3
sub 3 into 1,
2 (37-z) + 3z = 95
74 - 2z + 3z = 95
z = 21
sub z = 21 into 3,
y = 37 - 21
y = 16
therefore you sold 16 bracelets and 21 necklaces
Hi there! The answer is A. miles
We can find the miles someone would run during the marathon, by using the formula for the perimeter. This is:
2 × width + 2 x length.
Filling in this formula learns us that the distance that is run is measured in miles. The answer is A.
