Answer:
The cost for 1 necklace is $3.
Step-by-step explanation:
With the information provided, you can say that the amount spent in bracelets and necklaces is equal to the price per bracelet for the number of bracelets plus the price per necklace for the number of necklaces, which is:
c=3x+2y, where:
c is the total cost
x is the price per bracelet
y is the price per necklace
Now, you can say that c=21 and x=5 and solve for y to find the price per necklace:
21=(3*5)+2y
21=15+2y
21-15=2y
6=2y
y=6/2
y=3
According to this, the answer is that the cost for 1 necklace is $3.

What would be the range of possible whole number values (x) for a 3rd side of the triangle with two sides of 5 in. and 8 in.?
& Name one possible value for a third side?
Correct Answer Only
Answer:
Range of the third side of a triangle
Step-by-step explanation:
Any one side of a triangle must be shorter than the sum of the other two sides. Therefore, the third side length x must be between 5 and 35, not including those endpoints: 5 < x < 35. All whole numbers satisfying this range would form a triangle.
20 is a possible value for a third side

two speedboats leave the dock at the same time and travel in opposite directions. one travels 9 mi/hr faster than the other. After 2 hr the boats are 170 mi apart. How fast is each boat travelling ?
Answer: [tex]\frac{170}{X}[/tex]+[tex]\frac{170}{X-9}[/tex]=2
(=)17 0x +170x+1530=2x²+18x
(=)-2 x² +322x+1530=0
Δ=b²-4ac
Δ=115924
[tex]\sqrt{}[/tex]Δ=340,476>0
because Δ>0 so that 2 X
=>x₁=2 (true), x₂=-161(false)
X+9= 2+9=11
first travel 2 mi/hr
second travel 11 mi/hr

Answer:
7 / 6
Step-by-step explanation:
( 2x + 6 ) / 5 = 4x - 3
2x + 6 = 5 ( 4x - 3 )
2x + 6 = 20x - 15
20x - 15 = 2x + 6
20x - 2x = 6 + 15
18x = 21
x = 21 / 18
21 = 7 * 3
18 = 6 * 3
x = 21 / 18
= ( 7 * 3 ) / ( 6 * 3 )
x = 7 / 6
Hence proved.

Tom buys a boat from a friend, and will pay his friend the same amount of money each year until the boat is paid for. The following graph gibes the amount of money, in dollars, Tom owes his friend, as a function of the amount of time, in years.
The graph of amount Tom owes his friend after a given time, t, is a straight line graph with a negative slope
Please find attached the required example of a possible graph that shows the amount Tom owes his friend
Reason:
Let A represent the amount of money Tom buys the boat with, let x
represent the amount of equal payment made and y represents the
amount Tom owes the friend after a given time, t, we have;
y = A - x·t
Therefore, the slope of the graph formed is -x, the y-intercept of the graph
is A, from which the graph that gives the amount of money, in dollars, Tom
owes his friend, as a function of time, in years can be presented as follows,
using example values;
A = $25,000 (Amount the Tom agrees to buy the boat)
x = $5,000 (Amount Tom pays each year for the boat)
By plugging in the above example values, the attached graph can be drawn using MS Excel

Write an equation for a line in slope-intercept form that is perpendicular to the line y = 4x + 3 and passes through the point (-4, -2).
Answer: The equation of the line perpendicular to y = 4x + 3 and passes through the point (-4, -2) is y = -(1/4)x - 3.
Step-by-step explanation: An line perpendicular to perpendicular to the line y = 4x + 3 would have a slope that is the negative inverse of the refernce line. That would make the new line's slope -(1/4), the negative inverse of 4,
We can write the new new as y = -(1/4)x + b. b, the y-intercept, is +3 in the original equation, but it will change for the new line. We can calculate the new y-intercept by using the one point, (-4,-2) that we know is a solution for the equation (it falls on the line).
y = -(1/4)x + b
-2 = -(1/4)(-4) + b
-2 = 1+b
b = -3
The equation of the line perpendicular to y = 4x + 3 and passes through the point (-4, -2) is y = -(1/4)x - 3.

Austin, Kevin and Lisa have a total of $159. Austin has $11 more than Kevin. Lisa has twice as much money as
Keyin. How much money does Lisa have?
Answer:
Step-by-step explanation:
A+K+L=159
A-K=11
2K=L
Plug in 2K instead of L in the equation: A+K+L=159
A+3K=159
Plug in K+11 instead of A in the equation: A+3K=159
4K+11=159
4K=148
Kevin=$37
Pluge in 37 instead of K in the equation: A-K=11
A-37=11
Austin=$48
Plug in 48 instead of A and 37 instead of K in the equation: A+K+L=159
48+37+L=159
L=74

Answer:
(c) y = 3x +2
Step-by-step explanation:
The second given point is the y-intercept, telling you that the 'b' in the equation y = mx +b is 2. This eliminates the first and last choices.
Trying the other point in the two remaining equations shows you which one works:
(b) y = -3x +2
-1 = -3(-1) +2 . . . . not true
(c) y = 3x +2
-1 = 3(-1) +2 . . . . true
The equation of the line through the two points is ...
y = 3x +2
_____
Additional comment
If you plot the two points, you see the line connecting them must have a positive slope. Only the third choice has a positive slope and a y-intercept of 2.

Step-by-step explanation:
0.1 = 1/10
2 ⅒
Answer:
2 1/10
Step-by-step explanation:
To convert the decimal 2.1 to a fraction, just follow these steps:
Step 1: Write down the number as a fraction of one:
2.1 = 2.1
--------
1
Step 2: Multiply both top and bottom by 10 for every number after the decimal point:
As we have 1 numbers after the decimal point, we multiply both numerator and denominator by 10. So,
= (2.1 × 10)
(1 × 10) = 21
------
10
Now you have to simplify, 2 1/10.
