- - If a baker has 20 pounds, and looses 3/4 pounds, then we have to take away. Meaning to subtract.


♥ Start with turning 20 into a fraction.

\frac{20}{1} -  \frac{3}{4}

♥ Change this to addition.

\frac{20}{1} + \frac{-3}{4}

♥ Solve for that.

\frac{80}{4} + \frac{-3}{4}

♥ Combine.

\frac{80+-3}{4} = \frac{77}{4} =19.25

She has about 19 (rounded) pounds left.

Decimal exact: 19.25

Drag steps of the solution into order to solve for x in the equation 9(x + 3) = 108.
Marat540 [252]

Answer:

Given expression is,

9(x+3) = 108

In solving the equation the steps are as follows,

Step 1 : 9x + 27 = 108      ( By distributive property )

Step 2 : 9x = 81               ( Subtracting 108 on both sides )

Step 3 : x = 9                   ( Divide both sides by 9)

Hence, by the above explanation we can drag the steps of solution in correct order.

4. The cosine function can be made to have the same values as the sine function for each angle by including a shifted _______ in
r-ruslan [8.4K]

Answer: Option D

phase

Step-by-step explanation:

By definition, the cosine function has the following form

y = cos (x - \phi)

Where \phi is known as the phase angle

By definition the sinx function is equal to the cosx function with a phase shift of \frac{\pi}{2}

So if we have the function

y = cos (x - \phi) and we want to transform it into the function y=sin(x) then \phi = \frac{\pi}{2}

Finally

y = cos(x - \frac{\pi}{2})=sin(x)

the answer is the option D
