Josephine and Edith both collect rubber-band bracelets. Josephine has 8 more than twice the
number of bracelets that Edith has. Which of the following equations best represents the
relationship between the amounts of Josephine's bracelets, j, and Edith's bracelets, e?
A e = 2 + 8
B j = 2e + 8
C 8 + e -2;
D8+ j = 2e
Answer:

why is math hard and important
Answer: Math seems difficult because it takes time and energy. Many people don't experience sufficient time to "get" math lessons, and they fall behind as the teacher moves on. Many move on to study more complex concepts with a shaky foundation. And then often end up with a weak structure that is doomed to collapse at some point.
Step-by-step explanation: math is important because some things in math are gonna be used in your daily life for example adding, subtracting, division Etc and also because Math helps us think analytically and have better reasoning abilities. Analytical thinking refers to the ability to think critically about the world around us. Analytical and reasoning skills are essential because they help us solve problems and look for solutions.

Hello.
The answer is choice A. angle 1 = 118, angle 2 = 118
Explanation:
The four angles above are congruent (meaning the same) to the ones beneath.
Angles 1 and 2 are also congruent, so they will measure the same.
Lets label the angles above A, B, C, D. B being the known angle, which is 118°. The angles beneath can be labelled E, F, G, H.
∠B ≅ ∠D
∠ABCD ≅ ∠EFGH
∠BD ≅ ∠FH
FH (or 1 and 2) equal 118.

List the following in order from least steep to most steep.
f(x)= -3/4x
g(x)= -5x
h(x)= 5/7x
j(x)= 11/3x
Answer:
h(x), f(x), j(x), g(x)Step-by-step explanation:
Given functions
f(x)= -3/4x g(x)= -5x h(x)= 5/7x j(x)= 11/3xTo compare steepness we'll compare absolute values of slopes
The steepness increases as the slope increases
The slopes are
3/4, 5, 5/7, 11/3Comparing the fractions
3/4 = 21/28, 5/7 = 20/28, so 3/4 > 5/7And
11/3 < 4So the order is
5/7 < 3/4 < 11/3 < 5As functions, the order is
h(x), f(x), j(x), g(x)Simplify the following numerical expressions.

How much is it | -7.9|?
Plllzzzzzz help mark you brainliest
Answer:
7.9
Step-by-step explanation:
When a number (or multiple numbers) is placed between two lines like this | |, that is the absolute value grouping symbol. Absolute value is the distance between the grouped number(s) and another defined number. In this case there are no other given numbers so 0 is assumed.
Now, say a friend is driving to your house and you call them to ask how far away they are from arriving (in distance), and they say "Around negative 5 miles away." That doesn't make sense! Distance can never be negative, and because absolute value is the distance between a number and another, a number within that grouping symbol can never be negative if there is a solution. Therefore, |-7.9| would be 7.9, because -7.9 is that exact amount away from 0.
a rectangle has a width of 2x + 1 and a length of 6X which expression describes this area
Given parameters:
Width = 2x + 1
Length = 6x
Unknown:
Expression for the area = ?
Solution:
The area of a rectangle is the space it occupies,
Area of rectangle = length x width
Input the parameter and solve;
Area of rectangle = 6x(2x + 1)
= 12x² + 6x
The area of the rectangle is 12x² + 6x

Given that f(x)=2x-1, find f(3)
Answer:
5
Step-by-step explanation:
Put 3 where x is and do the arithmetic.
f(x) = 2x -1
f(3) = 2·3 -1 = 6-1
f(3) = 5
The cost of renting a canoe is $5.25, plus $0.50 per hour for the time that the canoe is out. Which equation could be used to find C, the cost in dollars for using the canoe for H hours?
Answer:
C = 5.25 + 0.50H
Step-by-step explanation:
gah, I'm never sure how to explain my work in these sorts of problems. hopefully I was able to help anyways!
Answer:
c=(5.25+0.50H
Step-by-step explanation:
Me up rich goes to the skate park and tents a skateboard for 4.00 per hour they make him rent a helmet for one time 6.00 fee if he only has $30 to spend at the park then select the equation that can be used to calculate h the number of hours he can rent the skateboard
Let, x be the maximum hours he can rent skate board and helmet.
So, total price :
T = 4x + 6x
Now, it is given that he has only $30.
Therefore,
Total price should be less than or equal to $30.
4x + 6x ≤ 30
10x ≤ 30
x ≤ 3
Therefore, the maximum number of hours he can rent the skateboard is 3 hours.
Hence, this is the required solution.

Step-by-step explanation:
In a function the x values cannot repeat. Look at each answer choice and see if an x repeats:
The first choice (top left) has the x value, -6, repeating. It cannot be a function.
The second choice (top right) does not have an x value repeat. This makes it a function!
The third choice, (bottom left) does not have an x value repeat. This makes it a function!
The fourth choice, (bottom right) does not have an x value repeat. This makes it a function!

an object is moving at a speed of 4 yards every 6.5 days. express this speed in centimeters per minute. round your answer to the nearest hundredth
Answer:
0.0390cm/minStep-by-step explanation:
We are expected to do a unit conversion here.
let us convert days to minutes first
6.5days to minutes
1 day has 1440miuntes
6.5 days has x minute
cross multiply we have
x=6.5x1440
x=9360minute
let us convert yards to cm
1 yard to 91.44 cm
4 yards has xcm
cross multiply we have
x=4x91.44
x=365.76cm
the speed in cm per mins is
speed=365.76/9360m
speed=0.0390cm/min

Let's see what to do buddy...
_________________________________
Step (1)
We know that the sum of the interior angles of any n-sided figure is obtained from the following equation :
[tex](n - 2) \times 180[/tex]
Our figure has 5 sides ;
So , sume the interior angles of it equals :
[tex](5 - 2) \times 180 = 3 \times 180 = 540 \\ [/tex]
_________________________________
Step (2)
First look at the photo which I post.
According it we have :
[tex](180 - x) + 120 + 85 + (2x - 10) + 90 = 540 \\ [/tex]
[tex]2x - x + 475 - 10 = 540[/tex]
[tex]x + 465 = 540[/tex]
Subtract the sides of the equation minus 465 :
[tex]x = 540 - 465[/tex]
[tex]x = 75[/tex]
_________________________________
And we're done.
Thanks for watching buddy good luck.

In △FGH, FH ≅ FG. Which angles are congruent? Select both angles that are congruent
angles FGH and FHG
Step-by-step explanation:
Since this is a triangle, and the question states that FH=FG, you know that the triangle is an isosceles triangle. If you use an isosceles triangle, you know that the bottom two angles are the same degrees. Since the F is the same for both lines, you can determine that F is the top point of the triangle. As such, is you draw the triangle out, you will find the answer is angles FGH and FHG
