Answer:
hey! This was the only part of mathematics I ever enjoyed! So consider this both of our lucky days: Answer is : (2,7)
Step-by-step explanation:
basically plug in Y to the first equation as sox + 4(-x + 9) = 30
x - 4x + 36 = 30- 3x = - 6
x = 2
then plug that in to Y!
Y = -(2) + 9
so Y = 7
and our answer is : (2,7)

Answer: Brielle will run the marathon faster.
Brielle = 104.8 minutes
Joshua = 157.2 minutes
Step-by-step explanation:
Speed rate = distance /time
Brielle = 1.25 /10 = 0.125 miles per minute
Joshua = 1.5/18 = 0.083333 =1/12 miles per minute
Since 0.125 (Brielle) > 1/12 (Joshua)
Brielle will run the marathon faster.
To calculate the time that takes each one to run the entire race (13.1 miles)
Time= distance / speed
- Brielle = 13.1 /0.125 = 104.8 minutes
- Joshua = 13.1 / (1/12)= 157.2 minutes

Answer:</h2>
Option: D is the correct answer.
The property which is illustrated by the given statement is:
D. Identity Property of Addition
<h2>
Step-by-step explanation:</h2>
We know that an identity is a value which when added to any element of the set gives the resultant as the element itself.
Also, we know that the identity under addition is always: zero.
Because when zero is added to any number then the resultant is the number itself i.e. adding zero does not affect the value.
Hence, by the Identity Property of Addition we have:
0 + x = x
