Need help plz
Answer
12x+40
Step-by-step explanation:
when distributing, you have to multiply all numbers in the parentheses by the variable outside the parentheses
Answer:
he distributed incorrectly. the correct answer is 12x + 40
Step-by-step explanation:
so you have to multiply 4×3x and 4×10

Find the missing endpoint if one endpoint is at (5.-7) and the midpoint is at (15.1).
Answer:
(25, 9)Step-by-step explanation:
Given Point (5, -7) and midpoint (15, 1)To findMissing endpointSolutionMidpoint formula:
x = (x1 + x2)/2, y = (y1 + y2)/2Substituting values:
15 = (5 + x2)/2 ⇒ 5 + x2 = 30 ⇒ x2 = 30 -5 ⇒ x2 = 251 = (-7 + y2)/2 ⇒ -7 + y2 = 2 ⇒ y2 = 2 - (-7) ⇒ y2 = 9Missing endpoint is:

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

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

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.

A contractor bought 6.4 ft2 of sheet metal. He has used 2.1 ft2 so far and has $77.40 worth of
sheet metal remaining. The equation 6.4x - 2.1x = 77.4 represents how much sheet metal is
remaining and the cost of the remaining amount. How much does sheet metal cost per square
foot?
Answer:
$18
Step-by-step explanation:
Given:
6.4x - 2.1x = 77.4
Where,
x = cost of sheet metal per square foot
How much does sheet metal cost per square foot?
6.4x - 2.1x = 77.4
4.3x = 77.4
Divide both sides by 4.3
x = 77.4 / 4.3
= 18
x = $18
Sheet metal per square foot cost $18

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

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

The highest point on Earth is Mount Everest with a height of 8,848 meters. The lowest point on Earth is the Mariana Trench, with a height of -11,034 meters. A height of 0 corresponds to sea level (the height of the world's oceans). What is the vertical distance between Mount Everest and Mariana Trench? Write the expression then solve it.
Answer:
The vertical distance between Mount Everest and Mariana Trench will be 19,882 ft
Step-by-step explanation:
Here, we want to get the vertical distance between the highest point on the Earth and the lowest point on the Earth
To find the vertical distance, we simply subtract the height of the lowest point from the height of the highest point
Mathematically, that would be;
8848 - ( 11, 034) = 19,882 ft
