For part B i dont know
Answer: x=−2 and y=9.
Step-by-step explanation: x+y=7
x+y+−y=7+−y
x=−y+7
2x+y=5
2(−y+7)+y=5

Brice is taking a bike tour of the city. The entire tour is 24 7/10 kilometers long. Brice knows that his average biking rate is 4.3 meters per second.
Question 1
Part A
What is Brice's average biking rate in kilometers per hour?
Enter the correct answer in the box.
Answers
Brice's average biking rate in km/h is 15.48km/h.
To solve this problem, we just have to convert his speed/velocity from m/s to km/h
Data;
Distance = 24 7/10Speed = 4.3 m/sConversion from meter per seconds to kilometer per hour[tex]1000m = 1km\\and \\(60*60)s =1hr\\[/tex]
This will bring 4.3m/s to
[tex]4.3m/s = km/hr\\\\4.3m/s= 4.3*\frac{(60*60)}{1000} \\4.3m/s = 15.48km/h[/tex]
Brice's average biking rate in km/h is 15.48km/h.

How can you use mental math and the inverse property of addition to find the sum [5.5+(-2.3)] +(-5.5 + 2.3)?
Answers
Answer:
To use mental math and the inverse property of addition to find the sum [5.5+(-2.3)] +(-5.5 + 2.3), you can use the following steps:
Rewrite the expression as [5.5+(-2.3)] +(-5.5) + 2.3.
Use the inverse property of addition to rewrite (-5.5) as 5.5, so the expression becomes [5.5+(-2.3)] +(5.5) + 2.3.
Use the inverse property of addition again to rewrite (-2.3) as 2.3, so the expression becomes [5.5+2.3] +(5.5) + 2.3.
Use the associative property of addition to rearrange the terms in the expression, so it becomes 5.5 + 2.3 + 5.5 + 2.3.
Use mental math to add the terms, which gives you a result of 15.8.
Therefore, the sum of [5.5+(-2.3)] +(-5.5 + 2.3) is 15.8.
Step-by-step explanation:

Step-by-step explanation:
Given
Compound event E
replace "image" with E in the question
Required
The probability of E
From the question, 4 outcomes were shaded.
This implies that
[tex]n(E) = 4[/tex]
And we have:
[tex]n(S) = 36[/tex] --- Sample size
The probability of E is:
[tex]Pr(E) = \frac{n(E)}{n(S)}[/tex]
This gives:
[tex]Pr(E) = \frac{4}{36}[/tex]
Simplify
[tex]Pr(E) = \frac{1}{9}[/tex]
Four friends are told that the average (mean) of their grades for their favorite class is 83.75%.
Kevin got 94%, Elizabeth got 78%, and Katherine got 83%.
Tyler's grade was not revealed. What's Tylers grade?
Answers
Answer:
Tyler got 80%.
Step-by-step explanation:
Represent Tyler's average by t.
Then .94 + .78 + .83 + t
-------------------------- = 83.75%
4
Multiplying both sides by 4, we get 2.55 + t = 3.35
so that t = 3.35 - 2.55 = 0.80
Tyler got 80%.

Cara's Candles Cara likes candles. She also likes mathematics and was thinking about using algebra to answer a question she had about two of her candles. Her taller candle is 16 cm tall. Each hour it burns makes the candle lose 2.5 cm in height. Her short candle is 12 cm tall and loses 1.5 cm in height for each hour that it burns.
Write an equation for both candles and solve it by either substitution or elimination.
(If someone could please help me out with this, I would really appreciate it. I've been trying to do this for days now and I just can't figure it out..)
(By the way, the equation for the 16 cm candle is y = -2.5x + 16, and the equation for the 12 cm candle is y = -1.5x + 12, I just don't know how to solve it using substitution or elimination.)
please help I don't understand

I really need the answers
Answers
Answer: Substitution
Step-by-step explanation: I think that because you have the equations already, you just have to solve for a variable using substitution. Do this by substituting one of the variables with another number. For example, make x=2 in both equations. Now you are free to solve for y and get your answer.
y=-2.5(2)+16
y=11
y=-1.5(2)+12
y=9
You can substitute in any number that makes it easy for you. Also, if you want x, you can substitute y. I'm really, really sorry if that is not helpful, I just told you what I know!

Rectangle = 9 * 18 = 162 ft^2
Now find area of triangle: bh/2
Base = 18 - 6 - 6 = 6
Height = 4
(6 * 4)/2 = 24/2 = 12 ft^2
Add rectangle and triangle areas
162 ft^2 + 12 ft^2 = 174 ft^2
Solution: A. 174 ft^2
Refer to the table shown. If the pattern continues what algebraic expression can be used to find the plants height for any month? What will be the plants height at 12 months?
Answers
Answer:Answer is 36 inches high.
Step-by-step explanation:
Each term is 3 times the number of months. So, the
expression is 3n.
3 3(12) n
Replace n with 12.
36
At the end of 12 months, the plant will be 36 inches high.
If you multiply one month by 12, you get 12 months.
Now if the plant grows 3 inches each month, and you are trying to find it’s height at 12 months multiply 3 and 12.
3 x 12 = 36 inches, which is your answer.
