Answer:

6

Step-by-step explanation:

We are going to use PEMDAS to solve this. PEMDAS stands for Parenthesis, Exponents, Multiplication, Division, Addition, and Subtraction. You use it to determine the order of operations you use.

So there are no parenthesis or exponents, so we skip right to multiplication.

3+3 x 3 - 3 + 3

^ 3 x 3 = 9

So now we have 3+ 9 - 3 +3

There is no division, so lets move to addition.

3+9 - 3 + 3

^ 12 ^ 6 Our equation is now 12-6

12-6 = 6, so the answer to this equation is 6

Need some help, kinda stuck

Answer:

7/4

Step-by-step explanation:

$\displaystyle\frac{2 + \sqrt{ - 3} }{2} ( \frac{2 - \sqrt{ - 3} }{2} )~~~~~~$

Evaluate.

Solution:

Rewrite it as,

$\displaystyle\frac{2 + \sqrt{ - 1 } \sqrt{ 3} }{2} ( \frac{2 - \sqrt{ - 1} \sqrt{3} }{2} )$
$\displaystyle\frac{2 + i\sqrt{ 3} }{2} ( \frac{2 - i\sqrt{ 3} }{2} )~~~~~~$

Multiplying them,

$\displaystyle\frac{(2 + i\sqrt{ 3})\times(2 - i \sqrt{3}) }{2 \times 2}$

$\displaystyle\frac{(2 + i\sqrt{ 3})\times(2 - i \sqrt{3}) }{4}$

Applying Distributive property,

$\displaystyle\frac{2(2 + i\sqrt{ 3}) + \: i \sqrt{3} (2 - i \sqrt{3}) }{4}$

$\cfrac{2 \times 2 + 2( - i \sqrt{3} ) + i \sqrt{3}(2 - i \sqrt{3} ) }{4}$

$\cfrac{2 \times 2 + 2( - i \sqrt{3}) + i \sqrt{3} \times 2 + i \sqrt{3} ( - i \sqrt{3}) }{4}$

Combining each terms,

$\cfrac{4 - 2i \sqrt{3} + 2i \sqrt{3} + 3}{4}$
$\cfrac{ - 2i \sqrt{3} + 2i \sqrt{3} + 7 }{4}$
$\boxed{\cfrac{ 7}{4} }$

Last Choice is accurate.

Brittany's mom gave her $15.00 to buy school supplies. Brittany needs to buy 3 notebooks and some mechanical pencils. If each no

ElenaW [278]

Answer:

4 mechanical pencils

Step-by-step explanation:

Each notebook is worth $2.99

So buying 3 of the notebooks would leave her with $8.97

Then, $15.00 - $8.97= $6.05
