() Are called parenthesis, and they are used to contain a part of a sentance or to seperate terms in math.

Examples:

I didn't want to explain (it was a long story).

2+3(2+1)

If the use is in math, you always do what is inside the parenthesis first.

For example:

2 * 2 + 2 + 1

4+2+1

6+1

7 is the answer when no parenthesis are added.

2 * (2 + 2) + 1

2 * 4 + 1

8 + 1

9 is the answer when parenthesis are added, because you do the operations inside of parenthesis first.

Hope this was helpful!

Answer: Quantity of Dark Chocolate used = 15 lb

Quantity of Milk Chocolate used = 35 lb

Step-by-step explanation:

Let x = Quantity of Dark Chocolate.

y = Quantity of Milk Chocolate.

As per given , we have the following system of equations:

$x+y= 50-------------(1)\\\\ 4x+2y=50\times2.60\\\\ 4x+2y=130-----------(2)$

Multiply equation (1) by 2 , we get

$2x+2y= 100-------(3)$

Eliminate equation (3) from equation (2) , we get

$2x=30\\\Rightarrow\ x=15$

Put x= 15 in (1) , we get $15+y=50$

⇒ y=35

Therefore , Quantity of Dark Chocolate used = 15 lb

Quantity of Milk Chocolate used = 35 lb

To find the number of possible combinations, you multiple the possible number of outcomes for each category together. For example, there are 5 choices of pastries, 4 choices of drinks, and 2 newspaper choices, so normally there are 5 x 4 x 2=40 possible combinations. Without a muffin, these numbers would change to 4 x 4 x 2=32. The difference would be 8 possible options, so choice C.

You lose 2 points every time you forget to write your name on a test. You have forgotten to write your name 4 times. What intege

Gelneren [198K]

Answer:

-8

Step-by-step explanation: since it says Times, (for me times is multiplication) you would multiply -2 and 4. negative 2 would be from that person losing 2 points. and 4 since it is your total amount of times you have forgotten to write your name. so, -2 x 4 = -8.

how i got -8. both signs from -2 and 4 are different, and when they are different the answer will always be negative.
