Answer:
white: $8double: $13Step-by-step explanation:
Let w and d represent the costs of white chocolate chip cookie dough and double chocolate chip cookie dough, respectively.
6w +12d = 204 . . . . . . Ryan's sale
7w +7d = 147 . . . . . . . . Cody's sale
We can divide out the common factor to put these equations into standard form:
w +2d = 34
w +d = 21
Subtracting the second of these equations from the first, we get ...
(w +2d) -(w +d) = (34) -(21)
d = 13
Using the second equation, we can find w:
w = 21 -d = 21 -13 = 8
The costs of the chocolate chip cookie dough packages are ...
white: $8
double: $13
(6,7) m=2/3 in standard form.

Please help me!! Find the equation of the line that is perpendicular to y=1/6x+3 and contains the point (-3,23).
Answer:
[tex]\displaystyle y = -6x + 5[/tex]
Where ? = -6.
Step-by-step explanation:
We want to find the equation of a line that is perpendicular to:
[tex]\displaystyle y = \frac{1}{6} x + 3[/tex]
And contains the point (-3, 23).
Recall that the slopes of perpendicular lines are negative reciprocals of each other.
The negative reciprocal of 1/6 is -6. Hence, the slope of the perpendicular line is -6.
We are also given that it passes through the point (-3, 23). Since we know the slope and a point, we can consider using the point-slope form:
[tex]\displaystyle y - y_1 = m(x - x_1)[/tex]
Substitute:
[tex]\displaystyle y - (23) = -6(x - (-3))[/tex]
Simplify:
[tex]\displaystyle y - 23 = -6 (x+3)[/tex]
Distribute:
[tex]\displaystyle y - 23 = -6x - 18[/tex]
And add. Hence:
[tex]\displaystyle y = -6x + 5[/tex]
In conclusion, our equation is:
[tex]\displaystyle y = -6x + 5[/tex]
Where ? = -6.

-5n-4(-7-4n)=36+7n
What is N?
Answer:
n=2
Step-by-step explanation:
-5n-4(-7-4n)=36+7n
Distribute
-5n +28 +16n = 36+7n
Combine like terms
11n +28 = 36+7n
Subtract 7n from each side
11n+28-7n = 36+7n-7n
4n+28 = 36
Subtract 28 from each side
4n+28-28 = 36-28
4n = 8
Divide by 4
4n/4 = 8/2
n=2

Exsplain how to use a number line to show that opposite quantities combine to make 0.
Answer:
Add a positive number to a number by counting up from that number, and add a negative number to a.number by counting down from that number.An integer plus its opposite sum to zero.The opposite of a number is called the additive inverse because the two numbers' sum is zero.Including a 5% sales tax, an inn charges $172.20 per night. Find the inn's nightly cost before tax is added.
The cost of the room before the tax is X.
To get the total cost they multiply the cost of the room x by 1 + sales tax rate.
Total cost would be x(1.05)
To find x divide total cost by 1.05:
Cost of room before tax: 172.20/1.05
Cost: $164

Answer:
it will take 36 months to completely pay the loan
Step-by-step explanation:
see that if the number of months paid is 1 and the amount owed is 2450 and that on number of months paid is 2 and then the amount owed is 2380
every month we have to substract 70
so we can make a pattern
0 months = 2520
1 month = 2450 that is 2520 - 70
2 months = 2380 that is 2520 - (2 × 70)
3 months = 2310 that is 2520 - (3 × 70)
.....
then it continues till n months
so
n months = 2520 - (n ×70)
n months = 2520 - (36 × 70)
36 months = 2520 - 2520

HELPPPP PLSSS You start at (3, -5). You move left 4 units and right 4 units. Where do you end? 4 3 IC 1 Х F -5 -4 -3 -2 -1 0 1 3 5 N -2 ܚ ܛ -5
Answer:
here you go :)
Step-by-step explanation:
You can approach this problem by thinking about going in the opposite of the directions indicated starting at the point (3, 4).
If you ended at an x-coordinate of 3 after having moved 4 to the left, then you can start at 3 and move 4 to the right to see what x -coordinate you started at: 3 + 4 = 7
The x coordinate of the STARTING point would have been 7.
You can do the same with the y-coordinate: start at 4 and travel down 1 unit. The y-coordinate of the STARTING point would be 3.
Therefore, the coordinates of the starting point would have been (7,3)
It was recommended that students drink 48 or more ounces of water.
How could you use a histogram to easily display the number of students
who drank the recommended amount?
Histograms are used to graph the frequency of data, where the length of the bar represents the frequency.
The number of students that drank the recommended amount of water are 125
Given that
[tex]Recommended = 40\ or\ more[/tex]
The number of students who drank the recommended amount are students whose frequency (i.e. length of bars) is 40 or more
From the histogram (see attachment), only 2 bars are above the frequency of 40.
And the number of students in these bars are: 50 and 75
[tex]Total =50 + 75[/tex]
[tex]Total =125[/tex]
Hence, the number of students that drank the recommended amount of water are 125

what does QR=?
Answer:
PQ=12
QR= 8
Hope it helps.
Answer: PQ = 12
QR = 8
Step-by-step explanation:
3x + 6 + 2x+4 = 20
5x = 20- 10
so, x = 2
so
PQ = 3x + 6 = 3*2+6 = 6+6 = 12
QR = 2x+4 = 2*2+4 = 4+4 = 8

If DE = 4 x + 10, EF = 2 x -1, and DF = 9 x - 15, what is the length of DF?
Answer:
DF = 57
Step-by-step explanation:
DE + EF = DF
(4x + 10) + (2x - 1) = 9x - 15
Combine like terms on the left side
6x + 9 = 9x - 15
Subtract 6x on both sides
9 = 3x - 15
Add 15 on both sides
24 = 3x
Divide by 3 on both sides
x = 8
DF = 9x - 15 = 9(8) - 15 = 72 - 15 = 57
Checking:
(4(8) + 10) + (2(8) - 1) = 9(8) - 15
(32 + 10) + (16 - 1) = 72 - 15
58 - 1 = 72 - 15
57 = 57
Answer:
DF= DE+EF
9x–15 = (4x+10)+(2x-1)
9x–15 = 6x +9
9x–6x= 9+15
3x = 24
x=24/3
x=8
DF = 9x –15 = 9(8)–15= 72 –15 = 57
So; DF = 57

Step-by-step explanation:
Solve for y. Simplify your answer as much as possible.
4=64/y
Answer:
y=16
Step-by-step explanation:
Multiply all terms by the same value to eliminate fraction denominators
Cancel multiplied terms that are in the denominator
Re-order terms so that constants are on the left
Divide both sides of the equation by the same term
Simplify
Cancel terms that are in both the numerator and denominator
Divide the numbers
Answer:
y is 16
Step-by-step explanation:
[tex]4 = \frac{64}{y} [/tex]
but 64 is 4³:
[tex]4 = \frac{ {4}^{3} }{y} [/tex]
make y the subject:
[tex]y = \frac{ {4}^{3} }{4} [/tex]
from law of indices:
[tex]y = 4 {}^{(3 - 1)} \\ y = {4}^{2} \\ y = 16[/tex]
