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

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
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
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.

(x+12)23-(2x-3)+16=12+5x-1
hmmmmmmmmm
Answer:
look at the attached picture
Answer:
X = -16.75
Step-by-step explanation:
Distribute.
(x + 12)23 = 23x + 276
12 + 5x -1 = 11 + 5x
Combine like terms.
23x - 2x - 5x = 16x
11 - (276 + 3+16 ) = -284
16x = -284
x = -17.75

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]
