The correct answer would be B. 0.94.

In order to find this, divide the numbers in the top of the table by those in the bottom. below are some examples for you:

53.99/59.21 = 0.91

62.05/66.27 = 0.94

81.47/87.54 = 0.93

Taking these values, we will note that the answer that is closest to all of these is B. 0.94

Explain how the words term and coefficient are used in talking about the algebraic expression.

cupoosta [38]

<h2>Answer:</h2>

The algebraic expressions are composed of several elements: Terms, Coefficients, Signs, Variables and Exponents. In this case we will focus on the first two.

The terms are composed of sign, coefficient, variable and exponent. The terms are separated from each other by the plus sign (+) or the minus sign (-).

For example, in the following expression:

2x-3x

We have two terms separated by the negative sign (-):

2x is the first term

-3x is the second term

Now, the coefficients are the numbers that multiply the variable. Note that if this coefficient is one (1) it is omitted .

For example in the following expression, the variable is x:

2x-3x+x

2 is the coefficient of x in the first term

-3 is the coefficient of x in the second term

1 is the coefficient of x in the third term, but is omitted

In order to understand this in a better way, see the figure attached, where the algebraic expression is composed by one term.

The price of a sweater was reduced from $20 to $12.By what percentage was the price of the sweater reduced?

Katen [24]

The price of the sweater was reduced by 40%

Step-by-step explanation:

Step 1; Cost before reduction was $20. The cost after reduction was 12$. Cost reduced= cost before reduction - cost after reduction

Cost reduced= $20 - $12 = $8

Step 2; We must find how much of the cost was reduced from the initial cost i.e. how much $8 is to $20. To do this we must convert it into a percentage. We divide the $8 with the $20 to get a value. This value must be multiplied with a 100 to be converted into a percentage.

Cost by which sweater was reduced= $\frac{8}{20}$ * 100 = 0.4 * 100 = 40

So the price of the sweater was reduced from $20 to $8 which equates to a reduction in 40%.
