The ages of three siblings combined is 27. The oldest is twice the age of the youngest. The middle child s three years older than the youngest. Write and solve an equation to find the ages of each sibling.
Answer:
The ages of the children are 6, 9 and 12.
Explanation:
Let x= the age of the youngest child.
If the oldest child is twice the age of the youngest, the age of the oldest child is twice x or 2x.
If the middle child is 3 years older than the youngest, the age of the middle child is x+3.
If the sum of their ages is 27, then
x+2x+x+3=27aaa(Combine like terms)
4x+3=27aaa
aa−3a−3aaa(Subtract 3 from both sides)
4x=24
4x4=24aaa(Divide both sides by 4)
Answer:
6, 9 & 12
Step-by-step explanation:
let x represent the age of the youngest kid
if the oldest kid is twice the age of the youngest, then it would be 2x
if the middle kid is 3 years older than the youngest, let this be x+3
if their ages in total is 27, then the equation is
x+2x+x+3=27
combine like terms first
4x+3=27
subtract 3 from both sides
4x=24
divide both sides by 4
you get 6. The youngest kid is 6.
For the oldest kid, the equation is 2x=2 times 6=12
the age of the middle child, equation is (x+3)=6+3=9

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
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

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
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.

[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]
