Answer:
x = 12
Step-by-step explanation:
Let the number be x.
9 added to twice a number is the same as 27 reduced by 4 times the number
If we add 9 to the number = (9+x)
If 27 reduced by 4 times the number = (4x-27)
ATQ,
(9+x) = (4x-27)
Taking like terms together,
x-4x = -27-9
-3x = -36
x = 12
Hence, the number be 12.

Use (2, 16) and (4,32) to find the constant of proportionality.
The unit rate (constant of proportionality) is
miles
hour
(Simplify your answer
Answer:
8 miles per hour
Step-by-step explanation:
First find the slope. The slope is the unit rate/constant of proportionality.
To find slope use the points given and formula y2-y1 / x2-x1
(32-16) / (4-2)
= 16 / 2
= 8
Thus the unit rate is 8 miles per hour.

Step-by-step explanation:
Hurry answer please
A) The distance between -5 and 0 is a Positive 5 because it takes 5 positive spots to go from -5 to 0.
B) The Absolute Value of -5 is 5. (Absolute Value means the distance from that number from zero) Is takes 5 spots to get to -5.
I hope this helps, and Happy Holidays! :)
Answer:
1) 5 units
2) 5
Step-by-step explanation:
absolute value is basiclly the opposite for example 4 would be -4 and -7 would be 7
also if it has lines like this: |2| it stays as it is so |3| is still 3 and |-5| is still 5
hope this helps :)

An equipment rental company charges $40 per day to rent a trench digger. A construction crew rented a trench digger for 6 days and paid 270. Write a linear equation in slope-intercept form that represents the total cost to rent the trench digger as a function of the number of days.
What should x and y equal, what is the y-intercept, and what is the equation
Answer:
Please check the explanation.
Step-by-step explanation:
We know that the slope-intercept form of the line equation is
[tex]y=mx+b[/tex]
where m is the slope or rate of change and b is the y-intercept
Let 'x' be the number of daysLet 'y' be the total costAn equipment rental company charges $40 per day to rent a trench digger.
It means the rate of change = $40 per day
We know that the rate of change is also termed as the slope.
Thus,
m = 40
Given that a construction crew rented a trench digger for 6 days and paid 270.
It means at x = 6, y = 270
substituting (x, y) = (6, 270) and m = 40 in the slope-intercept form to determine the y-intercept 'b'
y = mx+b
270 = 40(6) + b
270 = 240 + b
b = 270 - 240
b = 30
Thus, the y-intercepy b = 30
Now, substituting m = 40 and b = 30 in the slope-intercept form
y = mx + b
y = 40x + 30
Thus, the equation of line in the slope-intercept form is
y = 40x + 30
VERIFICATION:
Put x = 6, in the equation to determine the total cost for 6 days
y = 40x + 30
y = 40(6) + 30
y = 240 + 30
y = $270
Thus, the total cost for days rent = $270
Therefore, x must be equal to 6 i.e. x = 6 to find the total cost i.e. y = 270.
A small university enrolls in-state and out-of-state students. The number of students enrolled to their most recent freshman class was 243. The school reported that it enrolled seven in-state students for every two out-of-state students. How many of each type of student was enrolled in freshman class ?
please answer this as soon as you can and i will give you a brainliest.
thanks :)
Answer:
In-State = 189
Out-of State = 54
Step-by-step explanation:
In-State = 7
Out-of State = 2
In-State
7/9 = x/243
= 189
Out-of State
2/9 = x/243
= 54
what is 31 billion in scientific notation?
explain clearly <3 :D
Answer:
3.1*10^10
Step-by-step explanation:
31 billion would be written like that because... there are 9 0's left, and that goes up to 10 because i turned 31 to 3.1 not 31, so that value after a decimal point adds 1
factor 64x² + 114x + 81

At your birthday, 38 of the 24 guests were relatives. How many of the guests were NOT relatives?
Answer:
15 guests were not relative.
Step-by-step explanation:
It is given that,
At your birthday, 3/8 of the 24 guests were relatives.
No of relatives,
[tex]=\dfrac{3}{8}\times 24\\\\=9[/tex]
So, there are 9 relative at the party.
No of guests that are not relative,
= 24 - 9
= 15
Hence, 15 guests were not relative.

The ratio of cherry candies to grape candies in a bag is 3:5. After your friend eats half of the grape flavored candies and only one cherry flavored candy, the ratio of cherry to grape candies is 7:6. How many candies are left in the bag?
Answer:
65
Step-by-step explanation:
The computation of the number of candies left in the bag is as follows:
Let us assume the cherry candies be c ;
And, grape candies be g
Now the ratio between them is 3:5
And, in the case when half of the candies are eaten and one cherry is also eaten so the ratio is
(c - 1) ÷ (g ÷ 2) = 7 ÷ 6
After subsitution
It would be
(3 ÷ 5g - 1) ÷ (g ÷ 2) = 7 ÷ 6
Now after solving it,
g = 60
And, the c = 35
As the candies are half so it would be 30 now
So, the number of candies together is
= 35 + 30
= 65

Jessica and Raphael are saving money for concert tickets. Each friend starts with an amount and also saves a specific amount each week.
Jessica came up with the following equation to show the total, y, she has saved at the end of each week, x.
y = 10x + 20
Raphael created a table to show the total he has saved at the end of each week.
Weeks 0 1 2 3 4 5 6 7 8
Amount saved 40 46 52 58 64 70 76 82 88
After saving for a certain number of weeks, Jessica and Raphael will have each saved the same amount of money. How much money will they have each saved then?
Compare the rate at which each friend saves money.
Select the correct answer from the drop-down menu to complete the statement.
The rate at which Jessica is adding to her savings each week is $
1,4,6,8,or 10
more than the rate at which Raphael is adding to his savings each week.
Answer:
part 1: Jessica saved 100, Raphael saved 88
part 2: The rate at which Jessica is adding to her savings each week is $4 more than the rate at which Raphael is adding to his savings each week.
Step-by-step explanation:
First figure out how much money Jessica saved at the end of week 8, compared to Raphael.
Use x =8
y = 10*8 + 20 = 100
For Raphael it is shown in the table as 88.
Next figure out the rate Raphael saves. We can find the slope usng (y2-y1) / (x2-x1).
Using the table lets use (0,40) and (1,46)
46-40 / 1-0 = 6/1 = 6
So Raphael saves $6 each week. This is $4 less than what Jessica saves each week since the slope for her equation is 10 or $10 each week.
