Another neighbor said, “My age is the difference between twice my age in 5 years and and twice my age 5 years ago.” How old is this neighbor? A third neighbor had the same claim for 17 years from now and 17 years ago. How old is this neighbor?
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.
Use distributive property to write the expression as a product: 8 4y + 22+ 7y =
11y+30 Is the simplified equation. Not sure if this helps any but It's we're talking about rn ;-;

how many hundredths are in 11 wholes?
how many hundredths are in 3 tenths?
how many hundredths are in 11.3?
pls help!!!
Answer:
1) 11/100 or 0.11
2) 3/1000 or 0.003
3) 113/1000 0.113
Step-by-step explanation:
Firstly, hundredths is the same as 1/100.
Multiply every number by 1/100.
11/1 • 1/100 = 11/100 or 0.11
(Remember, 11 over 1 is the same as 1. Multiply the numerators and denominators and you get 11/100).
3/10 • 1/100 = 3/1000 or 0.003
11.3/1 • 1/100 = 113/1000 or 0.113
(Move the decimal once to the right to get rid of the decimal point).
Hope this helps!

Please find the measure of the exterior angle
Answer:
exterior angles:
144°and 36°
126° and 54°
90° and 90°
Step-by-step explanation:
we know that each angle in a triangle adds up to 180°.
so,
2x+3x+5x=180
10x=180
x=180/10
x=18
the interior angles are:
2x=36°
3x=54°
5x=90°
and explanation is provided to find the exterior angles above.(sorry for the bad handwriting)

what is the mean of this set
0,100,100,100,100
Answer:
80
Step-by-step explanation:
Mean simply means the average. To calculate the average of all these numbers, add them all up together and divide that number by how many numbers you added.
A simple equation you can use is:
[tex]\frac{the sum of the terms}{the number of terms}[/tex]
To calculate the mean of the set : 0,100,100,100,100
= 0 + 100 + 100 + 100 + 100
= 400 / 5
= 80
The mean of the set is 80.
A polygon is shown on the graph:
A polygon is shown on a coordinate plane. Vertex A is located at 2 comma negative 1, vertex B is located at 1 comma negative 4, vertex C is located at 3 comma negative 5, vertex D is located at 5 comma negative 3.
If the polygon is translated 3 units down and 4 units left, what will the coordinates of the new image be? Use prime notation in expressing the new coordinates.
Answer:
4 units left : subtract 4 from each x coordinate
3 units down : subtract 3 from each y coordinate

What are the Slope and Equation of the graph?
Answer:
Slope= -3
Equation: y=-3x-44
Question 3 What is the slope of the line that passes through the points (0.-7) and (-4, 3)? 0 -3/11 O -2/5 À O -5/2 0 10/4 Question 4
Answer:
Gradient = Change in y / Change in x
Gradient = (-7-3) / (0-4)
Gradient = -10/-4
Gradient = 2.5
So the answer is 10/4, which is 2.5
The slope of the line passes through the points (0.-7) and (-4, 3) is -5/2. The correct option is B.
What is a slope?Slope or the gradient is the number or the ratio which determines the direction or the steepness of the line. The slope is defined as the ratio of the rise to the run.
Given that the points are (0.-7) and (-4, 3). the slope of the line will be calculated as,
Slope = ( y₂ - y₁ ) / ( x₂ - x₁ )
Slope = ( 3 - (-7) / ( -4 - 0 )
Slope = 10 / -4
Slope = -5 / 2
