Write a system of equations to describe the situation below, solve using substitution, and fill in the blanks. Chase and his little brother made up a game using coins. They flip the coins towards a cup and receive points for every one that makes it in. Chase starts with 19 points, and his little brother starts with 27 points. Chase gets 3 points for every successful shot, and his brother, since he is younger, gets 1 point for each successful shot. Eventually, the brothers will have a tied score in the game. How many points will they both have? How many additional shots will each brother have made? Chase and his brother will both have a score of by making shots.
Answer:
Chase and his brother will both have a score of 31 points by making 4 successful shots.
Step-by-step explanation:
Given that initially Chase has 19 points and his brother has 27 points.
In one successful flip, Chase get 3 points and in one successful flip, his little brother get 3 points
Assuming that both have the same score after n number successful flip of the coin.
So, points earned by Chase in n successful flip [tex]= 3\times n =3n[/tex]
and points earned by his little brother in n successful flip [tex]= 1\times n=n[/tex].
Total points of Chase [tex]= 19+3n\cdots(i)[/tex]
Total points of his little brother [tex]= 27 + n\cdots(ii)[/tex]
As the brothers have tied scores in the game, that means both have the same score, so from equations (i) and (ii), we have
[tex]19+3n = 27 + n \\\\\Rightarrow 3n-n = 27-19 \\\\\Rightarrow 2n=8 \\\\\Rightarrow n=8/2=4[/tex]
So, after n successful throw, both have the same score.
Hence, each brother made 4 additional successful shots.
Now, put n=4 inequation (i) or (ii) to get the total points, i.e
Total points of each brother [tex]= 19+ 3\times 4 = 31.[/tex]
Hence, each brother has 31 points.

A plumber is connecting pipes in the shape of a triangle. Which of the following pipe lengths could form a triangle?
15,6,5
13,12,5
40,20,10
19,16,2
Answer: 13,12,5
Step-by-step explanation:
According to the triangles inequality : The sum of any two sides of a triangle must be greater than the third.
since [tex]6+5 =11 \ngtr 15[/tex]
[tex]20+10=30\ngtr40\\\\ 16+2=18\ngtr19[/tex]
Only pipe lengths with measure 13,12,5 can form triangle as
13+12 >5
12+5>13
13+5>12
Hence, the correct option is 13,12,5.

Write an equivalent expression. 1/3(12x+6x-21)=
Answer:
Step-by-step explanation:
1/3(12x+6x-21)
Take 1/3 of everything in the ()
4x+2x-7 combine like terms
6x-7
The equivalent expression is 6x - 7
Given the function 1/3(12x+6x-21), to get the equivalent expression, we will open the parenthesis using the distributive law;
= 1/3(12x+6x-21)
= 1/3(12x) + 1/3(6x) - 1/3(21)
= 4x + 2x - 7
On simplification, the resulting expression will be:
= 6x - 7
Hence the equivalent expression is 6x - 7

A rafter makes an angle of 22.5° with the roof joist, as shown
How tall is the board supporting the middle of the roof?
Answer:
≈ 5 ft
Step-by-step explanation:
Using the tangent ratio in the right triangle.
let the height of the board be h , then
tan22.5° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{h}{12}[/tex] ( multiply both sides by 12 )
12 × tan22.5° = h , then
h ≈ 5 ft ( to the nearest whole number )

A taxi driver had 27 fares to and from the airport last Monday. The price for a ride to the airport is $14, and the price for a ride from the airport is $7. The driver collected a total of $294 for the day. Let x represent the number of trips to the airport and y represent the number of trips from the airport. Write the ordered pair (x,y) that represents the solution in this situation.
Answer:
(15, 12)
Step-by-step explanation:
Let's generate two systems of equations that fit this scenario.
Number of trips to the airport = x
Number of trips from the airport = y
Total number of trips to and from the airport = 27
Thus:
[tex] x + y = 27 [/tex] => equation 1.
Total price for trips to the Airport = 14*x = 14x
Total price of trips from the airport = 7*y = 7y
Total collected for the day = $294
Thus:
[tex] 14x + 7y = 294 [/tex] => equation 2.
Multiply equation 1 by 7, and multiply equation 2 by 1 to make both equations equivalent.
7 × [tex] x + y = 27 [/tex]
1 × [tex] 14x + 7y = 294 [/tex]
Thus:
[tex] 7x + 7y = 189 [/tex] => equation 3
[tex] 14x + 7y = 294 [/tex] => equation 4
Subtract equation 4 from equation 3
-7x = -105
Divide both sides by -7
x = 15
Substitute x = 15 in equation 1
[tex] x + y = 27 [/tex]
[tex] 15 + y = 27 [/tex]
Subtract both sides by 15
[tex] y = 27 - 15 [/tex]
[tex] y = 12 [/tex]
The ordered pair would be (15, 12)

Answer: -10,-5,3,15
A,C,D,E
The next one is a= -5, b=1, c=-5, d=-12
The last one is 3 & 4
The rational root theorem is used to determine the potential roots of a function.
The potential roots are: [tex]\mathbf{-10, -5, 3, 15}[/tex]
The function is given as:
[tex]\mathbf{P(x) = x^3 + 6x^2 - 7x - 60}[/tex]
For a polynomial function:
[tex]\mathbf{P(x) = px^n +.............+ q}[/tex]
The potential roots are:
[tex]\mathbf{Roots = \pm \frac{Factors\ of\ q}{Factors\ of\ p}}[/tex]
The factors of 60 are:
[tex]\mathbf{60 = \pm 1, \pm 2, \pm 3, \pm 4, \pm 5, \pm 6, \pm 10, \pm 12, \pm 15, \pm 20, \pm 30, \pm 60}[/tex]
The factor of 1 is:
[tex]\mathbf{1 = \pm 1}[/tex]
So, we have:
[tex]\mathbf{Factors= \frac{\pm 1, \pm 2, \pm 3, \pm 4, \pm 5, \pm 6, \pm 10, \pm 12, \pm 15, \pm 20, \pm 30, \pm 60}{\pm 1}}[/tex]
