3 QUESTIONS !



1) I picked a number between 1 and 20. I multiplied my number by 6, added 8, divided it by 4, and then subtracted 5. This resulted in the number 3. What was my number?



2) I selected a number between 40 and 50. I divided my number by 9, subtracted 8, added 6 and then multiplied by 7. This resulted the number 21. What was my original number?


1) I picked a number between 100 and 110. I subtracted 4, added 11, multiplied it by 2, divided it by 6, and then subtracted 8. This resulted in the number 29. What was my original number?





Answers

Answer 1

Answer:

1) 4

2) 45

3) 104

Step-by-step explanation:

1)

let x be your number.

((6x+8)/4)-5 = 3

add 5

(6x+8)/4=8

multiply by 4 to get rid of the denominator

6x+8=32

subtract 8

6x=24

divide by 6

x=4

2) Same type. (this time I won't explain every step)

let x be your number

((x/9)-8+6)*7 =21

(x/9)-8+6=3

(x/9)-2=3

x/9 = 5

x=45

3) Same type... Again

let x be your number

(((x-4+11)*2)/6)-8 = 29

((x-4+11)*2)/6=37

(x-4+11)*2 = 222

x+7=111

x= 104

The polynomial P(x) = 3x^3-20x^2+37x-20 as a product of linear factors is P(x) = (3x - 5)(x - 1)(x - 4)

How to express as linear factors?

The polynomial is given as:

P(x) = 3x^3-20x^2+37x-20

The factor is given as: x - 4

This means that:

P(x)/x - 4 = 3x^3-20x^2+37x-20/x - 4

Factorize the numerator

P(x) = (3x - 5)(x - 1)(x - 4)/(x - 4)

Cancel out the common factors

P(x) = (3x - 5)(x - 1)(x - 4)

Hence, the polynomial P(x) = 3x^3-20x^2+37x-20 as a product of linear factors is P(x) = (3x - 5)(x - 1)(x - 4)

6(x−2)= −18
x=

Answers

answer: -1

explanation: you have to distribute the 6 to what’s in the parentheses first. when you do this you get 6x - 12 = -18. next, since 12 is negative, you will add it to both sides. when you do this, you get 6x = -6. lastly, you divide six on both sides. this gives you x = -1

Answer:

x = -1

Step-by-step explanation:

Distribute the 6

Then add 12 to both sides

Next divide both sides by 6

Your answer should be -1.  :)

6x-12= -18

   +12    +12

6x= -6

|2x-8| + 3 = 5 two solutions

Answers

Answer:

The two solutions are 5 and 3

Step-by-step explanation:

The equation of the absolute has two solutions because IxI = a means x = a and x = -a

Let us solve the question using this fact

I2x - 8I + 3 = 5

→ Subtract 3 from both sides

∴ I2x - 8I + 3 - 5 = 5 - 3

∴ I2x - 8I = 2

By using the fact above

1st solution

2x - 8 = 2

→ Add 8 to both sides

∴ 2x - 8 + 8 = 2 + 8

∴ 2x = 10

→ Divide both sides by 2 to find x

x = 5

2nd solution

2x - 8 = -2

→ Add 8 to both sides

∴ 2x - 8 + 8 = -2 + 8

∴ 2x = 6

→ Divide both sides by 2 to find x

x = 3

The two solutions are 5 and 3

Answer:

Step-by-step explanation:

we see here that angle RPN is 180 degrees. SPM is 90 degrees so

angle RPS + angle SPM + angle MPN = 180 degrees

(4y - 10) + 90 + y = 180

(4y - 10) + y = 90

5y - 10 = 90

Answers

Answer:

The value of x = 4 if g(x) = 6

Step-by-step explanation:

Given the function

[tex]g(x) = 3(x - 2)[/tex]

as

[tex]g(x) = 6[/tex]

so putting the value of [tex]g(x) = 6[/tex] in the function

[tex]g(x) = 3(x - 2)[/tex]

[tex]6 = 3(x-2)[/tex]

Switch sides and divide both sides by 3

[tex]\frac{3\left(x-2\right)}{3}=\frac{6}{3}[/tex]

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

[tex]x=4[/tex]

Therefore, the value of x = 4 if g(x) = 6

A nursery owner buys 8 panes of glass to fix some damage to his greenhouse. The 8 panes cost ​$18.80. ​Unfortunately, breaks 3 more panes while repairing the damage. What is the cost of another 3 panes of​ glass?

Answers

Answer:

Step-by-step explanation:

The cost of another 3 panes of glass would be

Solution:

Given, Number of panes of glass bought = 8

Cost of 8 panes of glass =

Number of broken panes of glass = 3

We have to find the cost of 3 panes of glass

By unitary method, If 8 panes of glass costs , then the cost of one pane of glass will be as follows,

Therefore, for 3 panes of glass it would be

Unitary method:

The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value. In essence, this method is used to find the value of a unit from the value of a multiple, and hence the value of a multiple.

$18.80/8= $2.35 each
$2.35X 3= $7.05

Write an equation for the line parallel to the given line that contains C.
C(-3,6); y=8/9x-2

Answers

Step-by-step explanation:

y = 8x/9 - 2

therefore m = 8/9

x1 = -3

y1 = 6

from, y - y1 = m(x-x1)

y - 6 = 8/9(x+3)

y-6 = 8x/9 + 8/3

y - 8x/9 -26/3 = 0 (×9)

Write down, and simplify, an expression for the candidate's total mark in terms of "a" and "c".​

Answers

Step-by-step explanation:

Total no. of questions = 20

Marks given for a correct answer = 4

Marks deducted for a wrong answer = 1

No. of questions attended by the candidate = a

No. of questions the candidate gets correct = c

No. of questions the candidate gets wrong = a - c

Marks obtained for correct answers = 4c

Marks deducted for wrong answers = 1 (a - c)

Total marks scored by the candidate =

Marks obtained for correct answers - Marks deducted for wrong answers

Total marks scored by the candidate = 4c - 1 (a - c)

how to solve 9x-2 × 27x=3
[tex] { {9}^{} }^{ x - 2 } .27 {}^{x} = 3[/tex]


Answers

Answer:

x = 1

Step-by-step explanation:

Using the rules of exponents

[tex](a^m)^{n}[/tex] = [tex]a^{mn}[/tex]

[tex]a^{m}[/tex] × [tex]a^{n}[/tex] ⇔ [tex]a^{(m+n)}[/tex]

Note that 9 = 3² and 27 = 3³ , thus

[tex]9^{x-2}[/tex] × [tex]27^{x}[/tex]

= [tex](3^2)^{x-2}[/tex] × [tex](3^3)^{x}[/tex]

= [tex]3^{2x-4}[/tex] × [tex]3^{3x}[/tex]

= [tex]3^{(2x-4+3x)}[/tex]

= [tex]3^{5x-4}[/tex] , then

[tex]3^{5x-4}[/tex] = [tex]3^{1}[/tex]

Since the bases on both sides are equal, equate the exponents

5x - 4 = 1 ( add 4 to both sides )

5x = 5 ( divide both sides by 5 )

x = 1
