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
Step-by-step explanation:
148.Add both not that hard.
76.91 = C
cos(77)= (17-3)/ C
2(a^2+b^2).
A^2 but b^2 = c^2 (area of triangle)
A trapezoid is two triangles put together i just say multiply those together
It’ll be D) 7/46 you can reduce it by dividing everything with 4
