Answer:
x = -5/21
Step-by-step explanation:
Step 1: Write equation
2(12x - 1) = (21x - 49)/7
Step 2: Solve for x
Multiply both sides by 7: 14(12x - 1) = 21x - 49Distribute 14: 168x - 14 = 21x - 49Subtract 21x on both sides: 147x - 14 = -49Add 14 to both sides: 147x = -35Divide both sides by 147: x = -5/21Related Questions

Answers
Answer:
[tex]x=11\\j=54\\k=54\\m=126[/tex]
Step-by-step explanation:
The two angles [tex](11x+5)[/tex] and [tex](5x-1)[/tex] are supplementary angles, meaning that their degrees add up to 180°. To find the value of [tex]x[/tex], we can use the following equation:
[tex](11x+5)+(5x-1)= 180[/tex]
Solve for [tex]x[/tex].
[tex](11x+5)+(5x-1)= 180[/tex]
[tex](16x+4)=180[/tex]
[tex]16x=176[/tex]
[tex]x=11[/tex]
After finding the value of [tex]x[/tex], plug the values into the equations.
[tex]11x+5=[/tex]
[tex]11(11)+5=[/tex]
[tex]121+5=126[/tex]
[tex]5x-1=[/tex]
[tex]5(11)-1=[/tex]
[tex]55-1=54[/tex]
Check to make sure your angles add up to 180.
[tex]126+54=180[/tex]
To figure out the rest of our angles, we must look at the given figures. Our 54° angle ([tex]5x-1[/tex]) and [tex]j[/tex] are vertical angles. Vertical angles are congruent which means [tex]j=54[/tex]. Our 126° angle ([tex]11x+5[/tex]) and [tex]m[/tex] are also vertical angles which means [tex]m=126[/tex]. Angle [tex]j[/tex] and angle [tex]k[/tex] are alternate interior angles. Alternate interior angles are also congruent which means [tex]k=54[/tex].
[tex]j=54\\k=54\\m=126[/tex]

Step-by-step explanation:
5 can be rewritten as [tex]\frac{5}{1}[/tex]
to divide fractions just multiply them by the reciprocal.
[tex]\frac{5}{1} / \frac{5}{12}[/tex]
becomes
[tex]\frac{5}{1}*\frac{12}{5}[/tex]
to multiply fractions multiply the numerator, then the denominators together.
5 * 12 = 60

Scores on the Welcher Adult Intelligent Scale (a standard IQ test) for the 20 to 34 age group are approximately normally distributed with μ=110 and σ=25. At what percentile is an IQ score of 150? (meaning at most 150, less than 150, or x ≤150). NOTE: μ is the population mean, and σ is the population standard deviation. Z= (x-μ)/σ and x is the score.Required to answer.Single choice.Immersive Reader
Answers
Answer:
94.52% or 94.52 percentile
Step-by-step explanation:
Z= (x-μ)/σ
μ is the population mean, and σ is the population standard deviation.
μ=110 and σ=25, x = 150( IQ score)
Z = 150 - 110/25
= 40/25
Z = 1.6
Probability value from Z-Table:
P(x≤ 150) = 0.9452
Converting to percentage = 0.9452 × 100
= 94.52% or 94.52 percentile
The tables for f(x) and g(x) are shown below. What is the value of (f-g)(5)
Answers
Answer:
16
Step-by-step explanation:
(f - g)(5) = f(5) - g(5)
From the table
(f(5) = 29 and g(5) = 13 , thus
f(5) - g(5) = 29 - 13 = 16
The value of function (f-g)(5) will be 16.
What is a function?A statement, principle, or policy that creates the link between two variables is known as a function.
The tables for f(x) and g(x) are shown.
Then the value of (f-g)(5) will be
(f – g)(5) = f(5) – g(5)
(f – g)(5) = 29 – 13
(f – g)(5) = 16

Which is not a necessary activity in building and protecting wealth? Entry field with incorrect answer Managing cash for liquidity and emergencies Writing a will Buying property and liability insurance Investing to achieve long-term goals
Answers
Answer: Writing a Will
Step-by-step explanation:
When a will is written, it is usually in place for how a property or assets should be shared amongst a deceased family should he die. A Will is not a way or means of protecting and building wealth, rather it aids the splitting up or sharing of the wealth which have been acquired over the life time of the deceased.
Writing a will is not a necessary activity in building and protecting wealth.
This is so because the writing of a will, by itself, does not constitute an act that implies the generation or protection of assets or dividends, but rather the distribution of the same before the death of its owner.
