Answer:

C. $Cos(28) = \frac{15}{17}$

Step-by-step explanation:

Recall: SOHCAHTOA

Thus,

$Cos(\theta) = \frac{Adjacent}{Hypotenuse}$

Reference angle = 28°

Adjacent = 15

Hypotenuse = 17

Plug in the values

$Cos(28) = \frac{15}{17}$

Answer:

$\frac{1}{4} (x-5)=13$

Step-by-step explanation:

So when we multiply this is what we get:

$\frac{x-5}{4}=13$

then we multiply the 4 by 13:

$x-5=52$

then after that we add 52+5 and we get:

$x=57\\$

Seven x's and 3y's cost as much as 4z's. One z costs as much as 1x plus 1y together. How many x's cost as much as 1y?

Pie

Answer:

Step-by-step explanation:

Equations

7x + 3y = 4z

Second equation

x + y = z Multiply the entire equation by 4

4[x + y = z] Now distribute the 4 through the equation

4x + 4y = 4z Both equations = 4z. Equate the lefts.

Third equation

7x+3y = 4x + 4y Subtract 3y from both sides

7x + 3y -3y = 4x + 4y -3y

7x = y + 4x Subtract 4x from both sides

7x - 4x = y + 4x - 4x Combine

3x = y

Answer: 3x = y
