The third angle is 48 degrees. The second part, I think should be b < a < c because you can go across from the angles shortest to largest.

Sheila bought 10 1⁄2 oz of almonds for $3.36. how much did the almonds cost per ounce?

Verdich [7]

Cost per ounce means you take the cost and divide it by the cost:

3.36 / (21/2) 

division of fractions changes to the multiplication of the reciprocal: 

3.36 * (2 / 21) 

3.36 and has 21 as a factor, so let's cancel it: 

0.16 * 2 

$0.32 per ounce

Question 3

igor_vitrenko [27]

Answer:

The system has exactly one solution where x = 0 and y = -3.

Step-by-step explanation:

-6x + y = -3

7x - y = 3

(7x - 6x) + (y - y) = 3 - 3

x + 0 = 0

x = 0

7(0) - y = 3

0 - y = 3

-y = 3

y = -3

-6(0) + y = -3

0 + y = -3

y = -3

So, the system has exactly one solution where x = 0 and y = -3.

Hope this helps!

Help me please. How to prove this ?

podryga [215]

Answer:

First, you want to divide the numerator and denominator by the cosine(x), and afterwards, it looks like this...

$\frac{tan~x+1}{tan~x-1}$

Include 45 as one of the parameters and correlate with tan.

$\frac{tan~x+tan~45}{tan~x-tan~45}$

Next, you want to multiply the numerator and denominator by the conjugate of the denominator, in this case, tan x + tan 45.

Lastly, simplify, and you have the answer as tan(45 + x)
