Let the price of pens be p.
Cameron buys 4 notebooks and 2 packages of pens for $16. This will be:
4n + 2p = 16 ..... equation i
Olivia buys 5 notebooks and 1 package of pens for $14.75. This will be:
5n + p = 14.75 ..... equation ii
Combining both equations will give us:
4n + 2p = 16 ..... i
5n + p = 14.75 ...... ii
Multiply equation i by 1
Multiply equation ii by 2
4n + 2p = 16 ....... iii
10n + 2p = 29.50 ...... iv
Subtract equation iii from iv
6n = 13.50
n = 13.50/6
n = 2.25
A notebook cost $2.25
Since 4n + 2p = 16 from equation I
4n + 2p = 16
4(2.25) + 2p = 16
9 + 2p = 16
2p = 16 - 9
2p = 7
p = 7/2
p = 3.5
A pen cost $3.50
What would the answer to this question be?
A. 40°
B. 60°
C. 80°
D. 100°
Answer:
D. 100°
Step-by-step explanation:
A straight line is 180°. Add 50° and 30° (which is 80°) and subtract the total from 180°.
50 + 30 = 80
180 - 80 = 100
Answer:
These angles form a straight line, so they are supplementary angles.
We know that, supplementary angles form 180°.
[tex]50 + x + 30 = 180 \\ 50 + 30 + x = 180 \\ 80 + x = 180 \\ x = 180 - 80 \\ x = 100[/tex]
=> So, the missing angles is 100°

3. Colin found apples on sale for 6 for $2.18. He wanted
to make some apples cider, and bought 4 dozen apples.
How much did he pay?
Answer: $17.44
Step-by-step explanation:
4 (dozens) ×12 (total number in a dozen) = 48 (total apples)
48÷6= 8. This was divided so there is equal groups of 6.
8 (number of groups of six) x 2.18 (cost of 6 apples)= 17.44
$17.44 was the total cost.

Colorado Springs sales tax is 8%. If you bought a sweatshirt for $20
(Remember money always has two decimal places: $0.00)
the amount of sales tax would be: $
the total purchase amount would be: $
Answer:
the amount of sales tax and the total purchase amount is $1.60 and $21.60 respectively
Step-by-step explanation:
Given that
The sales tax rate is 8%
And, the purchase price of sweatshirt is $20
We need to find out the sales tax and the total purchase amount
The sales tax is
= $20 × 8%
= $1.60
And, the total purchase amount is
= $20 + $1.60
= $21.60
Hence, the amount of sales tax and the total purchase amount is $1.60 and $21.60 respectively

Step-by-step explanation:
d = 2r = 2(2 m) = 4 m
C = πd = 3.14 × 4 m = 12.56 m
Answer:
C=12.56 m
Step-by-step explanation:
The radius is 2 m. To find the circumference, you need d, which is the diameter.
The diameter of a circle is 2 times the radius.
d=2*2=4
Now use the formula to find the circumference
C=3.14*4=12.56

Step-by-step explanation:
A card is drawn at random from a well-shuffled deck of 52 cards. what is the probability of drawing a face card or a spade?
Answer:
2/5 or 2:5
Step-by-step explanation:
Face Card:
The face cards in a deck are the Jack, Queen, and King. There are 4 of each card (1 in each suit), for a total of 12 face cards.
Spade:
1/4 of all the cards in a deck are spades, so 52/4= 13 spades.
When added, the numerator of the probability is 25, however, because the Jack, Queen, and King of Spades are duplicated, we have to subtract 3.
25-3=22
22/55
when simplified: 2/5

Prove or disprove the figure defined by points A, B, C, d is a rhombus
Answer:
It is not a rhombus, because all the internal angles are equal.
Step-by-step explanation:
A rhombus is a figure that has four sides of equal length, and 2 internal angles that are smaller than the other two internal angles.
First, let's look at figure ABCD.
We can see that all the sides have equal length by just counting the number of squares that each side takes (each side is 12 units long)
So now we need to see the angles.
Remember that if two lines are perpendicular, then the angle formed by those two lines is exactly 90°.
We can see that the segment BC is horizontal (the y-value of B is the same than the y-value of C)
While the segment CD is vertical (the x-value of C is the same than the x-vale of D)
Then one segment is horizontal, and the other is vertical, which means that the segments are perpendicular, thus the angle C is 90°.
Now we can do the same for segments CD and DA
We already know that CD is a vertical segment.
For segment DA we can see that the y-value of D is the same as the y-value of A, then this segment is horizontal, this means that segments CD and DA are perpendiculars, which means that D = 90°.
Because DA is parallel to BC, and CD is parallel to BA, we can conclude that:
A = 90°
B = 90°
Then all the angles are equal, so this is not a rhombus. (it is a square)
