Answer:
The neighbor is 20 years old.
The third neighbor is 68 years old.
Step-by-step explanation:
Equations
Let's set:
x=current age of the neighbor
x+5=his age in 5 years
x-5=his age 5 years ago
He claims that his age is the difference between twice his age in 5 years and twice his age 5 years ago. Then:
x = 2( x + 5 ) - 2( x - 5 )
Operating:
x = 2x + 10 - 2x +10
Simplifying:
x = 20
The neighbor is 20 years old.
Repeating for the other neighbor, a similar equation is established:
x = 2( x + 17 ) - 2( x - 17 )
Operating:
x = 2x + 34 - 2x +34
Simplifying:
x = 68
The third neighbor is 68 years old.
what is the inverse of the function f(x) = 2x+ 1?
A. h(x) = 1/2x -1/2
B. h(x) = 1/2x + 1/2
C. h(x) = 1/2x - 2
D. h(x) = 1/2x + 2
[tex]f(x) = 2x + 1[/tex]
[tex]y = 2x + 1[/tex]
Subtract sides -1
[tex]y - 1 = 2x + 1 - 1[/tex]
[tex]y - 1 = 2x[/tex]
[tex]2x = y - 1[/tex]
Divided sides 2
[tex] \frac{2}{2}x = \frac{y - 1}{2} \\ [/tex]
[tex]x = \frac{1}{2}y - \frac{1}{2} \\ [/tex]
Thus ;
[tex] {f}^{ - 1} = h(x) = \frac{1}{2}x - \frac{1}{2} \\ [/tex]

Chloe has 18inches of red licorice.Reid has 6inchex of red licorice. what fraction of a yard of red licorice do Chloe and Reid have together. use numbers pictures or Words to show your thinking
Answer:
2/3
Step-by-step explanation:
Chloe = 18inches of red licorice.
Reid = 6inches of red licorice
Total = 18 inches + 6 inches
= 24 inches
what fraction of a yard of red licorice do Chloe and Reid have together
Chloe and Reid have 24 inches altogether
1 yard = 36 inches
Fraction = 24 inches / 36 inches
= 2/3

USE FOR MASTERY Number of attempts allowed: 1 Write two rational numbers a/b and c/d, where a, b, c, and d are the digits 2, 3, 4, or 5, such that no digit can be used more than once and that the two rational numbers are the greatest distance apart on the number line. Explain how you got this answer.
Answer:
We want to craft:
a/b and c/d
where a, b, c and d can be 2, 3, 4 and 5.
Such that the distance in the number line between these two numbers is maximized.
Then we want one number to be really small, and the other to be really large.
Remember two things:
for numbers like a/b.
if a is smaller than b, then a/b is smaller than 1.
Now, if a is larger than b, then a/b is larger than 1.
And two things,
1/10 = 0.1
10/1 = 10
So when the numerator is larger, the distance displaced in the number line is larger.
Then we want to have:
a number where the numerator is the largest option and the denominator is the smallest option:
a/b = 5/2
And the two remaining options in such way that the numerator is smaller than the denominator:
c/d = 3/4.
The distance between these two numbers is:
D = 5/2 - 3/4 = 10/4 - 3/4 = 7/4.
The lines AB and CD are perpendicular to each other. If the slope of line AB is 2/3 then what is the slope of line CD
Answer:
-3/2
Step-by-step explanation:
you can find the perpendicular slope by putting the slope in 1/-m. M is the current slope you have or really you can flip it and change the signs so for example, 1/-(2/3) = -3/2
The slope of line CD is = -3/2
What are Perpendicular lines?A perpendicular is a straight line that makes an angle of 90° with another line.
Given that the lines AB and CD are perpendicular to each other, the slope of line AB is 2/3.
Slope of perpendicular lines are negative reciprocal of each other, so,
Hence, The slope of line CD is = -3/2

You start at (10, 1). You move down 1 unit and left 7 units. Where do you end?
Translation in right or left causes the x coordinate to change while translation in up or down causes the y coordinate to change.
Moving left or down causes the coordinates to be going negative.
Moving right or up causes the coordinates to be positive.
Original point (10, 1).
Down 1 unit:
(10, 1 - 1) = (10, 0)

2540 centimeters are equal to how many inches ?
Answer:1000
Step-by-step explanation
There are 1000 inches equal to 2540 centimeters
Unit conversion can be defined as the conversion from one quantity unit to another quantity unit followed by the process of division, and multiplication by a conversion factor.
To convert centimeters to inches, we have to use the conversion factor 1 inch = 2.54 cm.
To determine how many inches are in 2540 cm, first we divide 2540 by 2.54:
2540 cm ÷ 2.54 = 1000 inches
Therefore, we can conclude that 2540 centimeters are equal to 1000 inches.

No real Solutions
Step-by-step explanation:
Step one: The coefficient on -6x is -6. So b= -6
Step two: Add (b/2)^2 to each side. in our case it is 9
x^2-6x+9= -49
Step three: Factor left side
(x-3)^2 = -49
Step four: take the square root
x-3 = ±√-49
Step five: add 3 to both sides
x = 3 ± √-49
So there is no real solutions

plugs the drain and the tub fills for 6 more minutes, gaining
another 45 quarts of water. After a 15-minute bath, the person

28 is the LCM of 7 and 4
Answer:
Step-by-step explanation:
one away to find to find the least common multiple of two numbers is to first list the prime factors of each number. Then multiply each factor the greatest number of times it occurs in either number . if the same factor occurs more than once in both numbers, you multiply the factor the greatest number of times it occurs.

Avery and Carmen both have summer jobs Avery gets paid $360 every four weeks, and gets paid $480 every six weeks summer break lasts a total of 12 weeks who earn more money during summer break every earns dollars per week Carmen earns dollars per week
Answer:
Avery earns $1,080 during summer
Avery weekly earnings = $1,080 / 12
= $90
Carmen earns $960 during summer
Carmen weekly earnings = $960/12
= $80
Carmen earns more money during summer break
Step-by-step explanation:
Avery payment = $360 every four weeks
Carmen payment = $480 every six weeks
summer break lasts a total of 12 weeks
Avery pay during summer = Total summer break weeks / 4 weeks × payment per 4 weeks
= 12 / 4 × $360
= 3 × $360
= $1,080
Carmen pay during summer = Total summer break weeks / 6 weeks × payment per 6 weeks
= 12 / 6 × $480
= 2 × $480
= $960
Avery earns $1,080 during summer
Avery weekly earnings = $1,080 / 12
= $90
Carmen earns $960 during summer
Carmen weekly earnings = $960/12
= $80
Carmen earns more money during summer break
Answer:
Step-by-step explanation:
Avery earns $1080 in 12 weeks
Carmen earns $960 in 12 weeks
