Answer: 16

Step-by-step explanation: When you have a set of parentheses in an order of operations problem, you must simplify what's inside that set of parentheses first before you do anything else.

So our first step here is to subtract 6 - 8 which gives us -2.

So in our next step we have 3 (-2)² + 8 ÷ 2.

Now remember to do exponents before you multiply.

So (-2)² is just -2 × -2 or 4.

So in our next step we have 3 x 4 + 8 ÷ 2.

Now, we multiply so we have 3 x 4 which is 12.

So we have 12 + 8 ÷ 2.

Now we can divide.

8 ÷ 2 is 4 so we have 12 + 4 or 16.

So the answer to this problem is 16.

GarryVolchara [31]

Answer:

49%

Step-by-step explanation:

First find how much Alice is paying for the all three service currently.

Amount paid by Alice at present= 59 + 49 + 69 = $ 177

If she switches to 90 NOW plan, then the amount saved = 177 - 90 = $ 87

Percentage of savings = (saved amount ÷ total amount she was paying at present) * 100

$= \frac{87}{177}* 100\\\\= 49.15$

= 49 %

Luther earned some money doing odd jobs last summer and put it in a savings account that earns 3% interest compounded quarterly

inysia [295]

The function we have to use in this case is

$m(t)=m_o\cdot(1+\frac{0.03}{4})^{4t}$

where mo is the initial amount of money. After 2 teats we get that

$\begin{gathered} m_0\cdot(1+\frac{0.03}{4})^8=800 \\ m_0\cdot1.06=800 \\ m_0=\frac{800}{1.06}\approx754.71 \end{gathered}$

SO he earned 755 approximately
