Write an expression that is equivalent to the following:
x + x + x + x - 20
​

Answer:

[tex]x=\frac{-17+\sqrt{97}}{6}[/tex], [tex]x=\frac{-17-\sqrt{97}}{6}[/tex]

Step-by-step explanation:

Use the quadratic formula to solve for all real solutions.

Quadratic formula: [tex]x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}[/tex]

Plug in and solve:

[tex]x=\frac{-17\pm\sqrt{17^2-4(3)(16)}}{2(3)}\\\\x=\frac{-17\pm\sqrt{289-4(3)(16)}}{2(3)}\\\\x=\frac{-17\pm\sqrt{289-12(16)}}{2(3)}\\\\x=\frac{-17\pm\sqrt{289-192}}{2(3)}\\\\x=\frac{-17\pm\sqrt{97}}{6}\\[/tex]

Since that's the farthest we can simplify to, your answers would be the positive and negative versions of the expression:

[tex]x=\frac{-17+\sqrt{97}}{6}[/tex]

and

[tex]x=\frac{-17-\sqrt{97}}{6}[/tex]

Answer:

a) x = -6

Step-by-step explanation:

5x - 14 = 8x + 4

-14 = 3x + 4

-18 = 3x

x = -6

Answer:

A) 5 (-6) - 14 = 8 (-6) + 4

- 30 - 14 = - 48 + 4

- 44 = - 44

Answer:

15:2

Step-by-step explanation:

If you take 45 / 6 you will end up with 7.5

You can't have a ratio with a fraction. So to get a whole number you multiply 7.5 by 2 to get a full number. Therefore 15:2

Step-by-step explanation:

To convert 10,009 to 17%, turn 17% to decimal and multiply that by 10,009 (10,009 * 0.17), which equals 1,701.53

IF you meant to convert the fraction 10,009/17% (read as "10,009 out of 17 percent, ") then simply convert 17% to a decimal (0.17) and divide 10,009 by 0.17 (10,009/0.17) which is about 58,876.47, for full decimal, use a calculator and do 10,009/0.17

Answer:

0.12 = 12% probability of first selecting a PRIME number, replacing it, then selecting a number less than or equal to 3

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

Probability of independent events:

Suppose we have two events, A and B, that are independent. The probability of both happening is given by:

[tex]P(A \cap B) = P(A) \times P(B)[/tex]

In this question:

Event A: Selecting a prime number.

Event B: Selecting a number less than or equal to 3

Probability of selecting a prime number:

Between 1 and 10, we have 4 prime numbers(2,3, 5 and 7), out of 10. So

[tex]P(A) = \frac{4}{10}[/tex]

Probability of selecting a number less than or equal to 3:

Three numbers(1,2,3) out of 10. So

[tex]P(B) = \frac{3}{10}[/tex]

Probability of both:

[tex]P(A \cap B) = P(A) \times P(B) = \frac{4}{10} \times \frac{3}{10} = \frac{12}{100} = 0.12[/tex]

0.12 = 12% probability of first selecting a PRIME number, replacing it, then selecting a number less than or equal to 3

Answer:

The first step to dividing fractions is to find the reciprocal (reverse the numerator and denominator) of the second fraction. Next, multiply the two numerators. Then, multiply the two denominators. Finally, simplify the fractions if needed.

Answer:

Dividing by fractions is just like multiplying fractions, except for one additional step. To divide any number by a fraction: First step: Find the reciprocal of the fraction. Second step: Multiply the number by the reciprocal of the fraction. Third step: Simplify the resulting fraction if possible.

Answer:

29.9 °F

Step-by-step explanation:

The formular for mean is given as;

Mean = Sum of Terms / Number of terms

Number of terms = 6

Sum of terms = 35.5  + 30.8  + 27.3  + 32.1  + 23.8  + 29.9 = 179.4

Mean = 179.4 / 6 = 29.9

Answer:

b = 45.69

Step-by-step explanation:

5 x 5 = 25

25 x 2 & and a half = 45.69

In the inequality expression "11.3 > b/4.3," the variable "b" represents an unknown numerical value.

In the inequality 11.3 > b/4.3, b is the variable.

The inequality is stating that 11.3 is greater than the result of dividing "b" by 4.3.

The purpose of the inequality is to compare the value of 11.3 with the value of "b/4.3" and determine if 11.3 is greater or not.

The variable "b" can take any value that satisfies the inequality.

Hence, in the inequality b stands for unknown value or variable.

Answer:

n=1

Step-by-step explanation:

N is the number of times per year

Annually would be one time per year so n =1

Answer:

If interest is compounded yearly, then n = 1; if semi-annually, then n = 2; quarterly, then n = 4; monthly, then n = 12; weekly, then n = 52; daily, then n = 365; and so forth, regardless of the number of years involved. Also, "t" must be expressed in years, because interest rates are expressed that way.
