Please Help With Math Problem !! (explanation Needed) -3 + (8 2x)4 = 29

Answers

Answer 1

Answer:

x = -4

Step-by-step explanation:

To solve this type of question, put the term with the exponent on one side and the numerical term on the other side

∵ -3 + [tex](8-2x)^{\frac{5}{4}}[/tex] = 29

→ Add 3 to both sides

∵ -3 + 3 + [tex](8-2x)^{\frac{5}{4}}[/tex] = 29 + 3

∴ [tex](8-2x)^{\frac{5}{4}}[/tex] = 32

→ Remember is [tex]x^{\frac{m}{n}}[/tex] = a, then x = [tex]a^{\frac{n}{m}}[/tex], that means to move the exponent

   from one side to the other side reciprocal it

∴ 8 - 2x = [tex](32)^{\frac{4}{5}}[/tex]

→ Use your calculator to find the value of  [tex](32)^{\frac{4}{5}}[/tex]

∵  [tex](32)^{\frac{4}{5}}[/tex] = 16

∴ 8 - 2x = 16

→ Subtract 8 from both sides

∴ 8 - 8 - 2x = 16 - 8

∴ -2x = 8

→ Divide both sides by -2

x = -4

To check the solution substitute x by -4 in the left side and find its answer if it equals the right side, then the solution is right

∵ Left side ⇒ -3 + (8 - 2 × -4)[tex]^{\frac{5}{4}}[/tex] = -3 + (8 + 8)[tex]^{\frac{5}{4}}[/tex] =-3 + (16)[tex]^{\frac{5}{4}}[/tex]  = -3 + 32 = 29

∵ Right side = 29

∴ The solution is right

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

5y = 100

chips = 15

Step-by-step explanation:

{ c + p = 23

{ 1/4c + 1/2p = 7.75

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

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

|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

There is no penalty for not attempting a question. a candidate attempts "a" questions and get "c" correct. 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)

B.)f( x) = x + 2
C.)f( x) = - x + 2

Answers

Answer:

C

Step-by-step explanation:

Looking at the graph, we can see that the graph crosses the y-axis at y=2.

Hence, our y-intercept should be 2.

Therefore, we can eliminate A.

We also notice that the graph is downwards sloping.

Therefore, our slope is negative.

So, we can eliminate B.

Therefore, our answer must be C.

At a grocery store, the price of 3 cans of soup is $6.90. at this rate, how much would 10 cans of soup cost

Answers

Answer:

$23

Step-by-step explanation:

At a grocery store 3 cans of soup cost $6.90

3 cans = 6.90

1 can= 6.90/3

1 can = $2.3

Therefore the cost of 10 cans can be calculated as follows

1 can= $2.3

10 cans= 10×2.3

= $23

Hence 10 cans will cost $23

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
