We need to find the LCD first in order to add the fractions:
7*3 = 21
3*7 = 21
21*1 = 21
So the LCD is 21.
Next, we need to make sure that the fractions have the same denominator in order to add:
-6/7x - 5/21x + 1/3x = -48
-18/21x - 5/21x + 7/21x = -48
-16/21x = -48
Multiply both sides by the reciprocal of -16/21 (21/-16) to get x by itself:
(21/-16)(-16/21)x = -48(21/-16)
x = 63

Step-by-step explanation:
A scatterplot is used to display data for a runner where x is the number of miles run, and y is the time, in minutes, that it
takes to run that distance.
Which interpretation describes a line of best fit of y = 9.5x for the data in the scatterplot?
For each 1 minute, the runner ran 9.5 miles.
The missing choices are:
(A) for each 1 minute, the runner ran 9.5 miles.
(B) for each 9.5 minutes, the runner ran 1 mile.
(C) the minimum distance with a recorded time is 9.5 miles.
(D) the maximum distance with a recorded time is 9.5 miles.
Answer:
The interpretation that describes the line best fit of y = 9.5 x is: for each 9.5 minutes, the runner ran 1 mile. ⇒ (B)
Step-by-step explanation:
Since the equation of the line best fit is y = 9.5 x, where
x is the number of miles runy is the time in minutes9.5 is the rate of change of the time to the mileThe rate of change = change of y/ change of x
∵ y represents the time in minutes
∵ x represents the distance in miles
∴ The rate of change = minutes / mile
∵ The rate of change = 9.5 minutes / 1 mile
∴ The interpretation describes the line best fit is:
For each 9.5 minutes, the runner ran 1 mile

Greta learned that about 10% of people are left-handed. She ran 10 different simulations
using random digits to find the probability that there is a left-handed person in a group
of 5 randomly selected people. In the table below, O represents a left-handed person and
1 through 9 represent a right-handed person. Each row represents one simulation of 5 people.

Answer:6%
Step-by-step explanation:
Work it out smh
The probability that there is a left-handed person in a group of 5 randomly selected people is 6%
It is given that Greta learned that about 10% of people are left-handed.
It is required to find the probability that there is a left-handed person in a group of 5 randomly selected people.
What is probability?It is defined as the ratio of the number of favorable outcomes to the total number of outcomes in other words the probability is the number that shows the happening of the event.
We have a total number of people = 50 (because 10 rows and 5 columns)
In the question, it is given that the 0 represents a left-handed person.
Then the number of left-handed people = 3 (there are three zero's in the table)
We know:
[tex]\rm Probability = \frac{ favorable \ outcomes}{total \ outcome}[/tex]
[tex]\rm Probability= \frac{3}{50}[/tex]
Probability = 0.06 or
Probability = 0.06×100 ⇒ 6%
Thus, the probability that there is a left-handed person in a group of 5 randomly selected people is 6%

4x + 5 = 9 + 4x please answer
Answer:
no solutions
Step-by-step explanation:
4x + 5 = 9 + 4x
Subtract 4x from each side
4x-4x + 5 = 9 + 4x-4x
5 = 9
This is not a true statement so there are no solutions

Bob's Bagels offers pre-paid cards and has the specials shown. Carol has a $50 card she uses to buy coffee and a bagel each week. Diego has a $60 card he uses to buy tea and a breakfast sandwich each week. Write and solve an inequality to find the number of weeks in which the balance on Carol's card will be greater than the balance on Diego's card.
Answer:
50-3W ≤ 60-5w
Number of week = 5 days
Step-by-step explanation:
Given:
Carlo card = $50
Diego card = $60
Note:
Coffee and Bagel = $3
Tea and breakfast sandwich = $5
Computation:
Number of week = W
50-3W ≤ 60-5W
Number of week = 5 days
90. The number of daily evening newspapers in the United States has decreased by 46.5% to
389 newspapers between 2000 and 2015. How many daily evening newspapers were there in
2000? I
Answer:
700
Step-by-step explanation:
Given:
Daily evening newspapers in 2015 = 389
Percentage decrease from 2000 to 2015 = 46.5%
To find:
Number of newspapers in 2000 = ?
Solution:
Let the number of newspapers in 2000 = [tex]x[/tex]
When 46.5% of the total newspapers in 2000 ([tex]x[/tex]) is subtracted from the total newspapers in 2000 ([tex]x[/tex]), it will be equal to the number of newspapers in 2015.
Making the equation as per the given statement:
[tex]x-x\times 46.5\%=389\\\Rightarrow \dfrac{100x-46.5x}{100}=389\\\Rightarrow 53.5x=38900\\\Rightarrow x\approx \bold{727}[/tex]
Therefore, the answer is:
There were 727 newspapers in 2000.
Grayson works in a department store selling clothing. He makes a guaranteed salary
of $350 per week, but is paid a commision on top of his base salary equal to 20% of
his total sales for the week. How much would Grayson make in a week in which he
made $925 in sales? How much would Grayson make in a week if he made x dollars
in sales?
Step-by-step explanation:
a) $350 per week
20% commission on sales
For $925 in sales, commission is
20/100 × 925 = $185
Total earning = $350 + $185 = $535
b) For $x in sales, commission is
20/100 × x = 1/5 × x = x/5 or 0.2x
Total earnings = $350 + $ x/5 or $350 + $0.2x
Point P is the interior of ∠OZQ. If m∠OZQ = 125 and m∠OZP = 62, what is m∠PZQ?
Answer:
[tex]PZQ = 63[/tex]
Step-by-step explanation:
Given
[tex]OZQ = 125[/tex]
[tex]OZP = 62[/tex]
Required
Determine PZQ
Since P is an interior of OZQ, we have that:
[tex]OZQ = OZP + PZQ[/tex]
Solve for PZQ
[tex]PZQ = OZQ - OZP[/tex]
Substitute values for OZQ and OZP
[tex]PZQ = 125 - 62[/tex]
[tex]PZQ = 63[/tex]

The equation 36x^2 + 61x + 20 = 0 solves to x = -4/9 or x = -5/4
==========================================================
Explanation:
x = -4/9 or x = -5/4 .... given solutions
9x = -4 or 4x = -5 .... multiply both sides by denominator
9x+4 = 0 or 4x+5 = 0 .... get everything to one side
(9x+4)(4x+5) = 0 .... zero product property
y(4x+5) = 0 ...... let y = 9x+4
y*4x + y*5 = 0 .... distribute
4xy + 5y = 0
4x( y ) + 5( y ) = 0
4x( 9x+4) + 5( 9x+4 ) = 0 ... plug in y = 9x+4
4x*9x + 4x*4 + 5*9x + 5*4 = 0 ..... distribute
36x^2 + 16x + 45x + 20 = 0
36x^2 + 61x + 20 = 0
-----------------
The equation 36x^2 + 61x + 20 = 0 has the two solutions x = -4/9 and x = -5/4
We can use the quadratic formula to confirm this.
