To solve problems like these, we simply need to break down the words and form the equation.

In this case, we start off with "The quotient," so we know we are talking about division. Next, we see "of 24 and," which means it has to be "24/ something."

24/

Finally, for this one, we see "twice a number." Number almost always means the variable (n), while twice means 2. This gives us 2n.

24/2n

Using the reasoning above, we can see that the first problem could be represented by 24/2n.

For the second problem, we can use the same reasoning on different values. We start off with "4 times," which can be represented as 4*.

4*

Next, we have "a number," which as stated previously, is almost always our variable (n).

4*n OR 4n

Finally, we have "decreased by two." Decreased generally refers to subtraction, while 2 is the value we are subtracting.

4n-2

Using the reasoning above, we can see the equation to represent the second problem is 4n-2.

Bess [88]

Answer:

The sampling method used is a stratified sampling method

Step-by-step explanation:

sampling is the selection of a predetermined representative subpopulation from a larger population, to estimate the characteristics of the whole population.

Stratified sampling: Here, the total population are divided into subcategories (strata) before sampling is done. The strata are formed based on some common characteristics. In our example, the times of the day (morning, afternoon and evening) has widely varying atmospheric conditions which will add biases to the measurement of air quality. For example, the air in the morning if compared to the afternoon in an industrial area may be purer because of minimal industrial activity, hence effective comparison will be made by stratification.

we can name it as ∠EFG, ∠F , ∠GFE

This strikes out the option B that is ∠G

so option B is the answer

Martin is two years younger than three times his daughter Ada’s age. The sum of their ages is 54. If Ada’s age is given by a, th
Igoryamba

Answer:

  • Martin is 40 and Ada is 14

Step-by-step explanation:

  • Martin's age = m
  • Ada's age = a

<u>Martin is two years younger than three times his daughter Ada’s age:</u>

  • m = 3a - 2

<u>The sum of their ages is 54:</u>

  • m + a = 54

<u>Solving this equation for m:</u>

  • m = 54 - a

<u>Eliminate m:</u>

  • 3a - 2 = 54 - a

<u>Solve for a:</u>

  • 3a + a = 54 + 2
  • 4a = 56
  • a = 56/4
  • a = 14

<u>Find m:</u>

  • m = 54 - 14 = 40

Martin is 40 and Ada is 14
