Answer:

X= -8

Step-by-step explanation:

First you distribute the 5 to the parenthesis to get 5x-30+4=7x-10. Then subtract 14 on both sides to get 5x-16=7x. Next, subtract 5x from both sides to get -16=2x. Now you divide by 2 on both sides to get -8=x.

Answer: x = - 8

Step-by-step explanation:

The first step in applying the distributive property:

5 (x - 6) + 4 = 7x - 10

5x - 30 + 4 = 7x - 10

The second step is to combine like terms by subtracting 10 from -30, and subtracting 4 from - 20:

5x - 30 + 4 = 7x - 10

5x - 16 = 7x

The third step is to subtract 5x from 7x:

5x - 16 = 7x

- 16 = 2x

The last step is to divide each side by 2 to isolate the variable, or find x:

- 16/2 = 2x/2

- 8 = x

or x = - 8

[tex](2x - \frac{1}{3} ) - ( \frac{2}{x} + 1)[/tex]

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

[tex](2x - \frac{2}{x} ) + ( - \frac{1}{3} + 1)[/tex]

[tex] (\frac{2 {x}^{2} }{x} - \frac{2}{x} ) + ( \frac{ - 1}{3} + \frac{3}{3} )[/tex]

[tex] \frac{2 {x}^{2} - 2 }{x} + \frac{ - 2}{3} [/tex]

We want to write the given expression as a single fraction. We will get the fraction:

[tex]\frac{6*x^2 - 4*x - 6}{3*x}[/tex]

So we start with the expression:

[tex](2*x - \frac{1}{3}) - (\frac{2}{x} + 1)[/tex]

First, let's rewrite each of these parenthesis as fractions, we need to have the same denominator in all the terms, then in the first one we can multiply and divide by 3 (and in the second one we can do the same but with x) so we get:

[tex](\frac{3}{3} *2*x - \frac{1}{3}) - (\frac{2}{x} + 1*\frac{x}{x} )\\\\(\frac{6*x}{3} - \frac{1}{3}) - (\frac{2}{x} + \frac{x}{x} )\\\\\frac{6*x - 1}{3} - \frac{2 + x}{x}[/tex]

Now we must multiply and divide the left term by x, and the right term by 3, so we get:

[tex]\frac{x}{x} \frac{6*x - 1}{3} - \frac{2 + x}{x}*\frac{3}{3} \\\\\frac{6*x^2 - x}{3*x} - \frac{6 + 3x}{3*x} = \frac{6*x^2 - x - 3x - 6}{3*x}\\\\\frac{6*x^2 - 4*x - 6}{3*x}[/tex]

This is the fraction in its simplest form.

Answer: B. -4 < y < -1

Step-by-step explanation:

1. Subtract 2 from all three sides to isolate the variable in the center of the inequality

5 < 2 - 3y < 14

3 < -3y < 12

2. Divide each of the three sides by -3 to get y by itself, as each of the answers have y as independent.

3 < -3y < 12

-1, y, -4

3. Rearrange

-4 < y < -1 (b)

Answer:

k = ±6

Step-by-step explanation:

guess your question is 4k²–144 = 0??

4k² = 144

k² = 36

k²–36 = 0

(k+6)(k–6) = 0

k+6 = 0 | k–6 = 0

k = –6, k = 6.

Alternatively; k = ±6.

Answer:

x = 48.59 degrees

Step-by-step explanation:

Do sin-1(12/16) and put it in a calculator. After that, you will get your final answer as 48.59 degrees. This requires sin because the opposite angle is 12 for x. The adjacent angle is something else.

A difference of squares has the following form . Any two perfect squares connected by subtraction can be factored.

It factors to (a+b)(a-b).

Step-by-step explanation:

A binomial is an expression with only terms where at least one is a term with a variable. When we can factor for difference of squares, we can have two variable terms or just one with a constant.

A difference of squares has the following form . Any two perfect squares connected by subtraction can be factored.

Answer:

7.4 years

Step-by-step explanation:

This is a compound interest question, from the question, we know we are to find the time.

The formula for Time in compound interest =

t = ln(A/P) / n[ln(1 + r/n)]

Where:

A = Amount after time t = $4,020

P = Principle = Initial amount invested = $2700

r = Interest rate = 5.4% = 0.054

t = ??

n = compounding frequency = monthly = 12

t = ln(A/P) / n[ln(1 + r/n)]

t = In(4020/2700)/12[In(1 + 0.054/12)]

t = 7.388 years

Approximately = 7.4 years

To make it easy I am categorizing this in two groups. One is (xz^3), late us name it A and the other is after the multiplication sign that is (4x^4z^5) which we are naming B. Now 4 from b multiplies 1 from a(as there is no number which means there must be 1). In multiplication of power of bases we have to add the powers which means x from a × x^4 from b= x from a's power 1 + x from b's power 4=x^5 and repeating same process in case of z resulting in z^5.

Answer:

I think what you got is correct

The percentage of incorrect problems is 25%.

Option D is the correct answer.

The percentage is calculated by dividing the required value by the total value and multiplying by 100.

Example:

Required percentage value = a

total value = b

Percentage = a/b x 100

Example:

50% = 50/100 = 1/2

25% = 25/100 = 1/4

20% = 20/100 = 1/5

10% = 10/100 = 1/10

We have,

Number of problems = 20

Number of correct problems = 15

The number of incorrect problems.

= 20 - 15

= 5

The percentage of incorrect problems.

= 5/20 x 100

= 25%

Thus,

25% were incorrect problems

Answer:

The midpoint of PR is;

(a + b, c)

Step-by-step explanation:

Here, we want to get the coordinates of the midpoint of PR

To get these, we make use of the midpoint formula

Mathematically, that will be;

(x,y) = (x1+y1)/2, (x2+y2)/2

(x1,y1) = (0,0)

(x2,y2) = (2a+2b, 2c)

The midpoint is thus;

(2a+2b)/2 , 2c/2

= (a + b, c )
