A certain positive number is multiplied by 4, and then the result is subtracted from the original number. The result is 21 less
stira [4]

Answer:

The number is 7

Step-by-step explanation:

certain positive number: x

x is multipled by 4:

4x

result of this is subtracted from the original number:

so original number minus 4x,

x - 4x

the result is 21 less than 0, this means negative 21

x - 4x = 0 - 21 = -21

do algebra:

-3x = -21

multiply both sides by -1

3x = 21

divide both sides by 3

x=7

(certain positive number: x) is equal to 7

Jared bought a Suzuki 1000 for $12,698. If it depreciates at a rate of 11% per year, how much will it be worth in 3 years
Serga [27]
Original price = P = $12,698
Depreciation rate = r = 11% = 0.11
Time in years = t = 3
New price = A

The formula used will be:

A=P(1-r)^{t}

Using the values, we get:

A=12698(1-0.11)^{3}=8951.70

Thus, the worth of Suzuki after 3 years will be $8951.70

likoan [24]

Answer:

<u>The correct answer is B. 36</u>

Step-by-step explanation:

1. Let's review the information given for answering the question correctly:

Data set given:

18

36

11

45

36

19

14

18

36

2. What is the mode for this data set?

Let's recall that the Statistical Mode is the number that  is more frequently repeated in a group of numbers.  If no number is repeated, then there is no mode for the list or set.

In this specific set, we can notice that 18 is repeated two times and 36 is repeated three times. Therefore, the mode for this set of ages of people riding a bus is 36.

<u>The correct answer is B. 36</u>
