Use the function f(x) = 2x3 - 3x2 + 7 to complete the exercises

Answer:

x=3

Step-by-step explanation:

Step 1: Add two to 7 and inverse the minus 2

3x=7+2 3x=9

Step 2: Divide each number by 3.

3x/3=x and 9/3=3

so x=3

Step-by-step explanation:

The number of miles per year that he has rowed since he was given the machine will be Roughly 2000. Then the correct option is D.

Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.

The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.

A 63-year-old man has rowed around the world in his living room, according to a newspaper story. On a rowing machine that he received for his 50th birthday, he logged 24084 miles.

The number of miles per year is calculated as,

⇒ 24,084 / (63 - 50)

⇒ 24,084 / 13

⇒  1852.61 ≈ 2,000

The number of miles per year that he has rowed since he was given the machine will be Roughly 2000. Then the correct option is D.

Step-by-step explanation:

Average = total number of coins / number of students

If the mean number of coins with boys is 14, the total number of coins held by boys =  14 x 9 = 126

The total number of coins held by the students = total number of children x average number of coins held by the children

15 x 18 = 270

The total number of coins held by girls = 270 - 126 =144

The mean  number of coins for the girls = 144 / 6 = 24

Step-by-step explanation:

Steps for finding L.C.M of the given numbers :

[tex] \star[/tex] First of all find the prime factors of each numbers.

[tex] \star[/tex] Take out the common prime factors.

[tex] \star[/tex] Also take out the remaining prime factors.

[tex] \star[/tex] Multiply those all prime factors and obtain L.C.M. If there is not any common prime factors then their L.C.M is the product of the given numbers.

Now,let's find the least common multiple ( L.C.M ) of 45 and 120 following those steps :

prime factors of 45 = 3 × 3 × 5

prime factors of 120 = 2 × 2 × 2 × 3 × 5

Common prime factors= 3 and 5

Remaining prime factors = 2 , 2 , 2 and 3

Multiply all the prime factors to obtain L.C.M

Answer:

$12.5

Step-by-step explanation:

Since prize is split equally.

So, money received by each person

= 75/6

= $12.5

Answer:

 75°C = 5h

Step-by-step explanation :

1. Make sure your mind is fresh and that you understand each step before reading

2. 24 hours is equal to  360°C

3.  so now lets break up the hours. We can do this by choosing a simple degree that was given in the diagram. For example "Watching tv".

Tip : when choosing one of the degrees , ( i mean one of the choices like watching tv, playing and sleeping) , try choosing the simplest one , which has a simple number and a multiple of 360.

so now you want to know how many hours is 60 equal to .

= 360 ÷ 60 = 60   (this is to make sure the number is a multiple and will not be a decimal )

= 24 ÷ 6 = 4

this means Ali spend 4 hours watching tv

and by doubling that you get                    60°C = 4h

the amount of time he slept                     120°C = 8h

and you keep playing with the numbers like that

so for playing                                                

                                                                   60°C = 4h

                                             divide by 4    15°C =  1h

                                           × by 5             75°C = 5h

this means ali spends 5h playing , 8h sleeping, 4h watching tv and 7 h studding

Answer:

Step-by-step explanation:

4x - 9 = 9x - 34

-5x - 9 = -34

-5x = -25

x = 5

4(5) - 9 + 9(5) - 34

20 - 9 + 45 - 34

11 + 11 = 22

The value of CT such that J is the midpoint of CT will be 22.

The number system is a way to represent or express numbers.

A decimal number is a very common number that we use frequently.

Since the decimal number system employs ten digits from 0 to 9, it has a base of 10.

As per the given,

J is the midpoint of CT

CJ = JT

4x - 9 = 9x - 34

-9 + 34 = 9x - 4x

25 = 5x

x = 5

So CT = 2(CJ) = 2(4 x 5 - 9) = 22

Hence "The value of CT such that J is the midpoint of CT will be 22".
