Answers

Answer 1

Answer:

see explanation

Step-by-step explanation:

Given

2(2x - 1) = 3(x - 6) ← distribute parenthesis on both sides

4x - 2 = 3x - 18 ( subtract 3x from both sides )

x - 2 = - 18 ( add 2 to both sides )

x = - 16

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

Given

4(5 - 7b)- 4 = - 3(1 + 3b) ← distribute parenthesis on both sides )

20 - 28b - 4 = - 3 - 9b , that is

16 - 28b = - 3 - 9b ( add 9b to both sides )

16 - 19b = - 3 ( subtract 16 from both sides )

- 19b = - 19 ( divide both sides by - 19 )

b = 1

Solve the equation for x.

Answers

answer:

x=-2

Step-by-step explanation:

my suggestion for this problem and all problems like it would to turn everything into 6ths. 1/3 would become 2/6. and 2 would become 12/6. leave the negatives. now you'll add 2/6 to -12/6. which will equal 10/6. divide 10/6 by 5/6 and youll get -2. x=-2

Answer:

x = -2

Step-by-step explanation:

● (5/6)x - (1/3) = -2

Add (1/3) to both sides

● (5/6)x - (1/3) + (1/3) = -2 + (1/3)

-2 is (-6/3)

● (5/6)x = (-6/3) + (1/3)

● (5/6)x = -5/3

Move 5/6 to the other side and switch the places of 5 and 6

● x = (-5/3) × (6/5)

● x = -30/15

● x = -2

Answer: The numerical length of  [tex]\overline{SU}[/tex] is 20 units.

Step-by-step explanation:

i.e. [tex]\overline{SU}=\overline{ST}+\overline{TU}[/tex]             (i)

Since , it is given that ST=2x+6,TU=4, and SU=4x

The per capita (per person) income from 1980 to 2010 can be modeled by

f(x) = 2000(X – 1980) + 10,000

where x is the year. Determine the year when the per capita income was $18,000.

The per capita income was $18,000 in the year N.

Answers

Answer:

X= 1984

Step-by-step explanation:

f(x) = 2000(X – 1980) + 10,000

Where,

f(x)= per capita income

x= year

Find x when f(x)= $18,000

f(x) = 2000(X – 1980) + 10,000

18,000 = 2000(X - 1980) + 10,000

18,000 = 2000X - 3,960,000 + 10,000

18,000 = 2000X - 3,950,000

Add 3,950,000 to both sides

18,000 + 3,950,000 = 2000X

3,968,000 = 2000X

Divide both sides by 2000

X= 3,968,000 / 2000

= 1984

X= 1984

Therefore, the per capita income was $18,000 in the year 1984

Answer:

Step-by-step explanation:

Looking at the question, we can see that the media has already been grouped into 3 parts namely charcoal sketches, pencil drawings, and oil paintings. It has already been grouped into multiple groups for easy selection or identification.

Now this type of grouping is synonymous with cluster sampling because cluster sampling is a probability sampling technique in which the researchers divide the population into multiple groups known as clusters for research and this question clearly shows that the media has been grouped.

What is 5+x+11x=11x+11

Answers

Answer:

x = 6

Step-by-step explanation:

Solve for x:

11 x + x + 5 = 11 x + 11

Hint: | Add like terms in 11 x + x + 5.

x + 11 x = 12 x:

12 x + 5 = 11 x + 11

Hint: | Move terms with x to the left hand side.

Subtract 11 x from both sides:

(12 x - 11 x) + 5 = (11 x - 11 x) + 11

Hint: | Combine like terms in 12 x - 11 x.

12 x - 11 x = x:

x + 5 = (11 x - 11 x) + 11

Hint: | Look for the difference of two identical terms.

11 x - 11 x = 0:

x + 5 = 11

Hint: | Isolate terms with x to the left hand side.

Subtract 5 from both sides:

x + (5 - 5) = 11 - 5

Hint: | Look for the difference of two identical terms.

5 - 5 = 0:

x = 11 - 5

Hint: | Evaluate 11 - 5.

11 - 5 = 6:

Answer: x = 6

Answer:

x = 6

Step-by-step explanation:

5 + x + 11x = 11x + 11

5 + 12x = 11x + 11

5 + 1x = 11

1x = 6

x = 6

cans on this shelf were put into stacks of
five cans each, no cans would remain. If the
same cans were put into stacks of three cans
each, one can would remain. What is the
greatest number of cans that could be on
the shelf?​

Answers

Answer:

40

Step-by-step explanation:

Given that the number of cans are fewer than 50.

Let the number of cans = [tex]x[/tex]

It is given that no cans remain if they are put in the stacks of five cans each.

i.e. number of cans are a multiple of 5.

Let us have a look at the numbers in decreasing order which are multiples of 5 and are lesser than 50.

45, 40, 35, 30, ......

Now, let us check the numbers one by one.

If [tex]x=[/tex] 45,

Now, they are placed on stacks of three each and one can remains.

So, the remainder when [tex]x[/tex] is divided by 3 will be 1.

But when 45 is divided by 3, remainder is 0.

Now, let us check next greatest number, which is 40.

When 40 is divided by 3, the remainder is 1.

Therefore, greater number of cans can be 40.

d. $300.00

Step-by-step explanation:

Given that a cosmetologist must double her salary before the employer can realize any profit from  his/her work, for Miss. Mead to realize $50.00 profit on her work, you would have to determine the amount that doubles the salary of the cosmetologist and add the $50 needed as profit:

Time required for the balloons to meet = x

After x minutes the first balloon will be at position:

10 + 15x

And the second balloon will be at position:

150 - 20x

Since they meet after x minutes, their position must be same:

10 + 15x = 150 - 20x15x + 20x = 150 - 1035x = 140x = 140/35x = 4 minutes

6x + 2 = 9x - 4 help me please

Answers

Answer:

x=2

Step-by-step explanation:

Answer:

x = 2

Step-by-step explanation:

6x + 2 = 9x - 4

We want terms with x on the left side and numbers on the right side.

Subtract 9x from both sides.

6x - 9x + 2 = 9x - 9x - 4

-3x + 2 = -4

Subtract 2 from both sides.

-3x + 2 - 2 = -4 - 2

-3x = -6

Divide both sides by -3.

-3x/(-3) = -6/(-3)

x∈ ( - 9 ; + oo)

Answer:

x > -9

Step-by-step explanation:

you want to multiply both sides of the inequality by 3/1 to make

-1/1 (5x+3) < 42/1

any expression divided by 1 remains the same

-1 (5x+3) < 42/1 ⇒ - (5x+3) < 42/1 ⇒ - (5x+3) < 42

Where there is a - in front of an expression in parentheses, change the sign of each term in the expression

-5x -3 <42

Then move the constant to the right-hand side and change its sign

-5 < 42 + 3

Add the numbers and you'll get

-5x < 45

Divide both sides of the inequality by -5 and flip the inequality sign and your answer would be

x > -9

2(a+5)=-2 Step 1 distribute

2a+10=-2 Step 2 minus 10 on both sides

2a=-12      Step 3 divide but 2 on both sides

a=-6

Answer:

a=-6

Step-by-step explanation:

In order to solve for a, we must isolate a on one side of the equation.

[tex]2(a+5)=-2[/tex]

2 is being multiplied by (a+5). The inverse of multiplication is division. Divide both sides of the equation by 2.

[tex]2(a+5)/2=-2/2[/tex]

[tex](a+5)=-2/2[/tex]

[tex](a+5)=-1[/tex]

5 is being added to a. The inverse of addition is subtraction. Subtract 5 from both sides of the equation.

[tex]a+5-5=-1-5[/tex]

[tex]a=-1-5[/tex]

[tex]a=-6[/tex]

Let's check our solution. Plug -6 in for a and solve.

[tex]2(a+5)=-2[/tex]

[tex]2(-6+5)=-2[/tex]

[tex]2(-1)=-2[/tex]

[tex]-2=-2[/tex]

This checks out, so we know our solution is correct.

The solution to the equation 2(a+5)=-2 is a=-6

19.1 cubic feet

Answers

Answer:

the volume of the cylinder = 19.08 ft³

Step-by-step explanation:

given:

If the radius of the cylinder is 1.5 feet and the height is 2.7 feet,

find:

what is the volume of the cylinder? (Use 3.14 for pi.)

Volume of a cylinder = π r² h

where π = 3.14

radius (r) = 1.5 ft.

height (h) = 2.7 ft.

plugin values into the formula:

V = π r² h

V = 3.14 (1.5)² 2.7

V = 19.08 ft³

therefore,

the volume of the cylinder = 19.08 ft³
