Answer:

B. Writing an equation is the most useful

Step-by-step explanation:

We are required to find the best method which can be used to find the value of a variable.

Since, we know,

<em>While writing an equation, we assign the dependent variable in terms of the independent variable.</em>

These equations can be easily solved using the methods such as substitution and elimination.

Thus, they give the exact value of the variables.

While options A, C and D, does not give the value of the variables over the domain.

So, the best option useful to find the value of the variable is to write an equation.

That is, option B is the most useful.

Writing an equation would be most helpful, but depending on the situation drawing a diagram or reading a table could work better.

There are 2 different maps of California. The scale on the first map is 1cm to 20km. The distance from Fresno to San Francisco i
Oksi-84 [34.3K]

Answer:

75 km

Step-by-step explanation:

Given the following :

Scale on first map = 1cm to 20 km

Distance fromFresno to San Francisco = 15km on first map

Scale on 2nd map = 1cm to 100 km

1cm / 20km = 15km

Let of Distance from Fresno to San Francisco on 2nd map = d

1cm / 100km = d

1 : 20 = 15

1 : 100 = d

20/ 100 = 15/d

1/5 = 15/d

d = 15 * 5

d = 75 km

Identify this coefficient 8x
galben [10]

Answer:

  8

Step-by-step explanation:

The term 8x is a product (as is any term). It is the product of a constant coefficient (8) and a variable (x). The "coefficient" is the multiplier of the variable of interest, so is 8 in this term.

_____

The word "coefficient" is often used to refer to the constant multiplier in any term. For example, in the term 6xy, if we just ask for the coefficient, we are interested in the value 6.

On the other hand, if we ask for the coefficient of y in that term, we expect to be told it is <em>6x</em>. That is, the "coefficient" is the multiplier of the specified variable or constellation of variables.
