What is the difference of the fractions? Use the number line and equivalent fractions to help find the answer. Negative 2 and one-half minus (negative 1 and three-fourths) A number line going from negative 3 to 0 in increments of One-fourth. a \large -4\frac{1}{4} b \large -\frac{3}{4} c -4 d \large -\frac{1}{2}
Answer:
B)[tex]\frac{-3}{4}[/tex]
Step-by-step explanation:
We are supposed to find the difference of the fractions
a) [tex]-2\frac{1}{2}-(-1\frac{3}{4})[/tex]
[tex]=\frac{-5}{2}+\frac{7}{4}[/tex]
Using equivalent fraction
[tex]-\frac{5}{2} \times \frac{2}{2} = \frac{-10}{4}\\\Rightarrow \frac{-10}{4}+\frac{7}{4}[/tex]
Plot both fractions on number lines
So Using number line
[tex]\frac{-10}{4}+\frac{7}{4}=\frac{-5}{2}+\frac{7}{4}=\frac{-3}{4}[/tex]
So, Option B is true
Lori is president of a book club. She has a message she wants to get out to her book club members. On
Monday, she called one member and asked that member to call two other members by noon the next day and
repeat the message. How many calls were made by Friday afternoon?
Answer:
31 calls
Step-by-step explanation:
This method of information dissemination forms a tree diagram with a common factor of 2 for each next day.
On Monday, Lori made a call.
By noon on Tuesday (the next day), two calls were made by the initial member.
By noon on Wednesday, four calls would be made by the two members.
By noon on Thursday, eight calls would be made.
By noon on Friday, sixteen calls would be made.
Therefore,
total calls made by Friday afternoon = 1 + 2 + 4 + 8 + 16
= 31
x + 9 – 0.8x = 5.2x + 17 – 8 pls help
Answer:
X = 6x
Step-by-step explanation:
Simplifying
X + 9 + -0.8x = 5.2x + 17 + -8
Reorder the terms:
9 + X + -0.8x = 5.2x + 17 + -8
Reorder the terms:
9 + X + -0.8x = 17 + -8 + 5.2x
Combine like terms: 17 + -8 = 9
9 + X + -0.8x = 9 + 5.2x
Add '-9' to each side of the equation.
9 + X + -9 + -0.8x = 9 + -9 + 5.2x
Reorder the terms:
9 + -9 + X + -0.8x = 9 + -9 + 5.2x
Combine like terms: 9 + -9 = 0
0 + X + -0.8x = 9 + -9 + 5.2x
X + -0.8x = 9 + -9 + 5.2x
Combine like terms: 9 + -9 = 0
X + -0.8x = 0 + 5.2x
X + -0.8x = 5.2x
Solving
X + -0.8x = 5.2x
Solving for variable 'X'.
Move all terms containing X to the left, all other terms to the right.
Add '0.8x' to each side of the equation.
X + -0.8x + 0.8x = 5.2x + 0.8x
Combine like terms: -0.8x + 0.8x = 0.0
X + 0.0 = 5.2x + 0.8x
X = 5.2x + 0.8x
Combine like terms: 5.2x + 0.8x = 6x
X = 6x
Simplifying
X = 6x
Answer:
X=6x

Every month, Rachel gets a basic salary of $4000. She also gets a bonus of $200 for each policy she sells and a bonus of $50 for each client's compliant she resolves. Write an expression for her total salary for a month if she sells n policies an resolves x complaints
Answer:
4000+200n+50x=
Step-by-step explanation:
the amount of policies or complaints times the money she would get.
Answer:
4000+200n+50x
Step-by-step explanation:
since we dont know how many policies she will sell or how many complaints she will resolve, they need to be variables. so if
N= amount of policies sold
x= complaints resolved
then it would be 4000+200n+50x

Find the distance between the two points in simplest radical form.
(2,7) and (-7,-5)
Answer:
15
Step-by-step explanation:
Answer:
15
Step-by-step explanation:
Calculate the distance d using the distance formula
d = [tex]\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }[/tex]
with (x₁, y₁ ) = (2, 7) and (x₂, y₂ ) = (- 7, - 5)
d = [tex]\sqrt{(-7-2)^2+(-5-7)^2}[/tex]
= [tex]\sqrt{(-9)^2+(-12)^2}[/tex]
= [tex]\sqrt{81+144}[/tex]
= [tex]\sqrt{225}[/tex]
= 15

Writewrite an equation of the line passing through the point p (-2, 6) that is parallel to the line x= -5.
Answer:
Since the slope of the line x= - 5 is infinite
The line will be parallel to y axis.
And the line passes through - 2, so the equation will become x= -2

How long is 75% of a 24-hour day?
Answer:
18 hrs
Step-by-step explanation:
6hrs is 25%, so 6 times 3 is 18, Hope This Helps!
75% of a 24-hour day is 18 hour.
What is Algebra?A branch of mathematics known as algebra deals with symbols and the mathematical operations performed on them.
Variables are the name given to these symbols because they lack set values.
In order to determine the values, these symbols are also subjected to various addition, subtraction, multiplication, and division arithmetic operations.
Given:
75% of a 24-hour day
let 75% of 24 hour day be x.
So, 75% of 24 = x
x= 75/100 x 24
x= 3/ 4 x 24
x= 18 hours
Hence, 75% of a 24-hour day is 18 hour.
