can you please help me, I cannot find the answer I'm trying to do my homework so my teacher doesn't get mad at me​

Answer:

Option B: 6x-4=50; x=9 is the correct answer.

Step-by-step explanation:

Given that:

x is the variable used for number.

6 times a number means 6x and difference means subtraction.

Thus according to given statement;

6x - 4 = 50

Adding 4 on both sides

6x - 4 + 4 = 50+4

6x = 54

Dividing both sides by 6

[tex]\frac{6x}{6}=\frac{54}{6}\\x=9[/tex]

Hence,

Option B: 6x-4=50; x=9 is the correct answer.

Answer: B

Step-by-step explanation: You make the values in the parentheses equal to zero.

(X + 3) = 0

X = -3

A is wrong because the root would be 3, not negative 3. C is wrong because 3 isn’t guaranteed to be a root. D is wrong because -3 is a real solution.

Answer: A. Simple Random Sampling

Step-by-step explanation:

A simple random sampling technique could be explained as being the most basic and approach to choosing an unbiased Number of samples from a given population. This technique simply involves choosing a specified Number of samples at random (each member of the larger sample or population has equal Chance of being selected) from a larger sample or population. It does not require any sort of partitioning during selection. As in the scenario above, the deck of cards represents the large lr population from which 20 cards are to be selected, since the card has been shuffled then each card has equal Chance of being selected.

Answer:

17,500*20%= 3,500 of decrease each year by 5 (3,500x5) 17,500

17,500-17,500= o resale value

Step-by-step explanation:

Answer:

x = 6.1

Step-by-step explanation:

Reference angle = 29°

Hypotenuse = 7

Adjacent side = x

Applying trigonometric ration, we would have:

Cos 29 = x/7

Multiply both sides by 7

7*cos 29 = x

6.12233795 = x

x = 6.1 (nearest tenth)

Answer:

[tex] |x - 12| + 6 = 56 \\ x - 12 + 6 = 56 \\ x - 6 = 56 \\ \boxed{x = 62} \\ |x - 12| + 6 = 56 \\ - (x - 12) + 6 = 56 \\ 12 - x + 6 = 56 \\ - x + 18 = 56 \\ - x = 38 \\ \boxed{x = - 38} \\ \boxed{A. \: x = 62 \: or \: x = - 38}[/tex]

Answer: 24x + 125 > 550

Step-by-step explanation:

You get your hair done for $56.00 and you tip the hairdresser $20.00(D)

You have to subtract 56 from 20% than round the answer to the neared tenth.

========================================================

Work Shown:

s = sum of the heights of buildings A,B,C

s/3 = mean of the heights of buildings A,B,C

s/3 = 14.2

s = 3*14.2

s = 42.6

The buildings A,B,C have their heights add up to 42.6

--------------

r = sum of the heights of buildings A,B,C,D,E

r/5 = mean of the heights of buildings A,B,C,D,E

r/5 = 14.8

r = 5*14.8

r = 74

--------------

r-s = (sum of heights of A,B,C,D,E)-(sum of heights of A,B,C)

r-s = sum of the heights of buildings D and E

r-s = 74-42.6

r-s = 31.4

(r-s)/2 = mean height of buildings D and E

(r-s)/2 = 31.4/2

(r-s)/2 = 15.7 meters is the average height of buildings D and E.

Answer:

5 yards

Step-by-step explanation:

Given;

1 yard = 3 feet

The length of a room is 15 feet

Find;

The length of the room in yards

Set up a proportion;

[tex]\frac{1yard}{3feet}=\frac{x-yards}{15feet}[/tex]

Solve;

x = 5 yards

Answer:

A. 442.05

Step-by-step explanation:

✔️First find the radius of circle J:

θ = 43°

Acr length = 52.8

Thus,

Acr length = θ/360*2πr

Plug in the values

52.8 = 43/360*2*π*r

52.8 = 0.751r

Divide both sides by 0.75

52.8/0.75 = r

r = 70.4 (nearest hundredth)

✔️Find the Circumference of circle J:

Circumference = 2πr

Radius (r) of circle J = 70.4

Plug in the values

Circumference = 2*π*70.4

= 442.34

This is close to the answer in option A. Therefore, the answer is 442.05.

Answer:

The answer is 4 x p.

Answer:

-3.5

Step-by-step explanation:

Flip the equation so it's 0 - 3.5 which would give you -3.5

Answer:

- 3 [tex]\frac{1}{2}[/tex]

Step-by-step explanation:

Any number combined with it's opposite will make zero. The opposite of a number is the same number with it's sign flipped. For example, the opposite of 5 is -5, and the opposite of -3 is 3. If I combine any number, for example 10, with it's opposite, in this case -10, it will make zero. (10 - 10 = 0.) Hope this helps!

Answer:

Yes, x = 1/2 is a solution

Step-by-step explanation:

To see if it is a solution, plug it into the equation:

3(x + 1) = 3x + 3

3(0.5 + 1) = 3(0.5) + 3

3(1.5) = 1.5 + 3

4.5 = 4.5

Since this is true, x = 1/2 is a solution of the equation.

Answer:

[i] Area of Juan's garden:

Soln,

length(l)=16

width(w)=12

area(a)=?

Now,

a=l×w

=16×12

=192

[ii] Area of Matthew's garden:

Soln,

length(l)=18

width(w)=21

area(a)=?

Now,

a=l×w

=18×21

=378

So,the area ofJuan's garden=192

And

the area of Matthew's garden=378
