Answer:
A. 12 = 2x + 1.5y
B. 3 buckets of popcorn
Step-by-step explanation:
We know 12 is the total and the cost for is $2 EACH we are multiplying so it would be written as 2x same goes for the drinks except it would be 1.50y
Since we found the equation is 12 = 2x + 1.5y and we are told that y represents the number of drinks we can replace y with 4. It would look like this,
12 = 2x + 1.5(4)
After you multiply 1.5 by 4 you get 6.
12 = 2x + 6
-6 -6
6 = 2x
Now divide both sides by 2, that way you isolate the variable.
6/2 = 3
2x/2 = x
So we are left with x = 3, which means if they buy 4 drinks they will buy 3 buckets of popcorn.
Hope that helps and have a great day!

Step-by-step explanation:
A kayak is originally priced at $160. The online retailer gives a discount and the kayak is now priced at $88. Enter the percentage discount for the cost of the kayak.
Answer:An important category of percentage exercises is markup and markdown problems. For these, you calculate the markup or markdown in absolute terms (you find by how much the quantity changed), and then you calculate the percent change relative to the original value. So they're really just another form of "increase - decrease" exercises.
Step-by-step explanation:
Answer:
45%
Step-by-step explanation:
O= 160
C=88
160-88=72
72 ?
160 100
72 times 100=7200
7200/160=45

Step-by-step explanation:
Last week, Shiloh owed her brother $25.50. This week, she owes him another $6.30, for a total of $31.80.
The story above can be modeled by the addition problem -25.50 + (-6.30) = -31.80. Write a related story that is modeled by the division problem -31.80 ÷ 6 = -5.30.
Answer:
Sarah had $31.80 and she owed 6 friends money.So she owes each friend $5.30.

Solve the system by substitution. Check your solution.
y = 0.8 x + 7.2.
20 x + 32 y = 48.
a. (8, -6)
b. (5, 11)
c. (-4, 4)
d. (-10, 2)
Answer:
c. (-4, 4)
Step-by-step explanation:
y = 0.8x + 7.2
20x + 32y = 48
20x + 32y = 48
20x + 32(0.8x + 7.2) = 48
20x + 25.6x + 230.4 = 48
45.6x + 230.4 = 48
45.6x = -182.4
x = -4
y = 0.8x + 7.2
y = 0.8(-4) + 7.2
y = -3.2 + 7.2
y = 4

C. (-4,4)

Slopes of perpendicular lines are _____.
a. negative reciprocals
b. the same
c. reciprocals
d. opposites
Answer:
Correct: Option a. negative reciprocals
Step-by-step explanation:
Perpendicular lines are defined as those who intersect at an angle of 90°.
There is an easy way to find out if two equations of lines correspond to perpendicular lines or not.
If line 1 is
y=m1x+b1
And line 2 is:
y=m2x+b2
The condition for the lines to be perpendicular is that:
m1*m2=-1
Solving for m2:
[tex]\displaystyle m2 = -\frac{1}{m1}[/tex]
As seen, both slopes are negative reciprocals.
Correct: Option a. negative reciprocals

You decided to get the Cinemark Movie Pass. It is a flat
fee of $8 and an additional $11.00 per ticket.
Enter the equation of the line in y= mx + b form.
Answer:
y = 11t + 8
Step-by-step explanation:
Since the starting fee is 8 dollars and the additional costs are 11 dollars per ticket, you can write the equation as:
y = 11t + 8
Where "t" represents the amount of tickets bought.
The dimensions of the box below are reduced by half. What is the constant of proportionality between the volume of the new box and the volume of the original box? Alternative text A.1/2 B.1/4 C.1/8 D.1/16
Answer:
C. 1/8
Step-by-step explanation:
Dimensions of the Original Box:
Length = 40 inches
Width = 20 inches
Height = 8 inches
Volume of original box = L*W*H = 40*20*8 = 6,400 in³
Dimensions of the New Box (½ of the dimensions of the original box):
Length = ½*40 = 20 in
Width = ½*20 = 10 in
Height = ½*8 = 4 in
Volume of original box = L*W*H = 20*10*4 = 800 in³
Constant of proportionality between the volume of the new box and the volume of the original box = [tex] \frac{800}{6,400} = \frac{1}{8} [/tex]

An elevator started on the first floor, went up 18 floors, then came down 11 floors and went back up 16.
1 + 18 - 11 + 16
1 - 18 - 11 + 16
1 + 18 + 11 - 16
1 - 18 + 11 - 16
Answer:
1+18-11+16
Step-by-step explanation:
if the elevator went up it will be plus but if the elevator came down it will be minus and then you will get 1+18 because it went up and then it go down 11 floor and it will be 1+18-11 and then it went up again 16 floor so the last answer will be 1+18-11+16
