Bracelet cost = b
Necklace cost = n
15b + 8n = 500
19b + 24n = 980
Elimination method x -3
-45b - 24n = -1500
19b + 24n = 980
-26b = -520
b = $20 bracelets
Plug back in
19(20) + 24n = 980
380 + 24n = 980
24n = 600
n = $25 necklaces
Check:
15(20)+ 8(25)= 500
300 + 200 = 500
500 = 500 :)

Answer:
x=8
Step-by-step explanation:
This is a congruent triangle. If we use Pythagorean theorm, we can see that 3^2+y^2=25
y^2= 16
y=4
(y is the base of the small triangle)
and since the big triangle and the small triangle are congruent(the ratios are the same), 3 is half of 6, and so the base of the small triangle is half of the big triangle's.
4*2=8
x=8
