3n - 1
One less is subtracting one.
Answer:
[tex]1-3[/tex]n
Step-by-step explanation:
One less 3 times a number.
1 less is 1-.

Melissa makes and sells necklaces and bracelets. One day she made a total of 28 pieces of jewelry. On this day the number of bracelets crafted was 4 more than twice the number of necklaces.How many of each type of jewlery did she make that day
Answer:
Number of necklaces = 8
Number of bracelets = 20
Step-by-step explanation:
Given that:
Mellisa is making and selling the necklaces and bracelets.
Number of pieces of jewelry made on one day = 28
Number of bracelets was 4 more than the twice the number of necklaces.
To find:
Number of each type of jewelry made = ?
Solution:
Let number of bracelets = [tex]b[/tex]
Let number of necklaces = [tex]n[/tex]
As per question statement:
[tex]b+n=28[/tex] ...... (1)
[tex]b = 2n+4[/tex] ...... (2)
Putting the value of [tex]b[/tex] in equation (1):
[tex]2n+4+n=28\\\Rightarrow 3n = 28-4\\\Rightarrow 3n = 24\\\Rightarrow n =\bold{8}[/tex]
By equation (1):
[tex]b + 8 =28\\\Rightarrow b = \bold{20}[/tex]
So, the answer is:
Number of necklaces = 8
Number of bracelets = 20

Triangle a'b'c' is result of dilating abc about point a by a scale factor of 2/3. Determine whether each claim about the properties of abc and a'b'c' is true or false
Answer:
True , because all properties preserved under dilation from triangle abc to a'b'c'.
Step-by-step explanation:
Given : A triangle abc is dilated by a factor of 2/3 , result triangle a'b'c'
To find :After dilation, properties of triangle abc and a'b'c' is true or false.
Solution:
Dilation of a triangle are result either decrease or increase the corresponding length of triangle , its depends on by which scale factor triangle is dilated ,and dilation does not affect the angle measures of triangle.here scale factor is 2/3 so corresponding sides of triangle a'b'c' decreases.
So, dilation of triangle are not congruent but similar to the original triangle abc
Therefore , basic properties of triangle preserved under dilation of triangle by a scale factor.
Answer:
true

height versus age domain and range
Answer:
While there is a strong relationship between the two, it would certainly be ridiculous to talk about a tree with a circumference of –3 feet, or a height of 3000 feet. When we identify limitations on the inputs and outputs of a function, we are determining the domain and range of the function.
Step-by-step explanation:
The Pythagorean theorem is a2+b2=c2. Solve for b.
Answer: what is a and c
Step-by-step explanation:
We need a and c to solve for b.

The length of time, y hours, it takes to put a jigsaw puzzle together is inversely proportional to the number of children, x, working on it. It takes 16 children 6 hours to put the jigsaw puzzle together. How many children are needed to put the same jigsaw puzzle together in 4 hours?
Answer:
24 children
Step-by-step explanation:
If the length of time, y hours, it takes to put a jigsaw puzzle together is inversely proportional to the number of children, x, this is represented as;
[tex]y \alpha \frac{1}{x}\\y =\frac{k}{x}[/tex]
k is the constant of proportionality
If it takes 16 children 6 hours to put the jigsaw puzzle together, this means at x = 16, y = 6
Substitute:
6 = k/16
k = 6*16
k = 96
W are to find number of children needed to put the same jigsaw puzzle together in 4 hours, this is done by substituting k = 96 and y = 4 into the expression y = k/x
y = 96/4
y = 24
Hence it will take 24 children to put the same jigsaw puzzle together in 4 hours

A rectangle has a height of m + 8 and a width of 2m3 + m2 + 3m.
Answer:
A=2m⁴+17m³+11m²+24m
Step-by-step explanation:
The area of rectangle is length × width
A=LW
A=(m+8)(2m³+m²+3m)
A= 2m⁴+m³+3m²+16m³+8m²+24m
A=2m⁴+m³+16m³+3m²+8m²+24m
A=2m⁴+17m³+11m²+24m
