Answer:
- Walnuts - $1.25, chocolate chips - $3.25
Step-by-step explanation:
Let walnuts = x, chocolate chips = y
<u>Set a system and solve:</u>
<u>Double the first equation and subtract the second one from it:</u>
- 6x + 10y - 6x - 2y = 40 - 14
- 8y = 26
- y = 26/8
- y = 3.25
<u>Find the value of x:</u>
- 6x + 3.25*2 = 14
- 6x = 14 - 6.5
- 6x = 7.5
- x = 7.5/6
- x = 1.25
(You forgot to provide the choices!?!)
A.) Cos Z = b/c
B.) Sin X= c/b
C.) Tan X = b/a
D.) Tan Z = a/b
B is the answer, Sin X = c/b is wong because Sin X= b/c ( sin = opposite/ hypotenuse)
Hope this helps.!

Answer:
10.3 miles
Step-by-step explanation:
a^2 + b^2 = c^2
9^2 + 5^2 = c^2
81 + 25 = c^2
106 = c^2
the square root of 106 and c^2 is approximately c = 10.3
