Answer:
72 Tires
18 Vehicles
1 Hour
4 people
Step-by-step explanation:
First, times the amount of Tires and Vehicles by 3, because that would make it 2 people and 1 Hour.
Second, times the amount of People by 2.
Since we have twice the People, we have twice the Tires and Vehicles!
Hope this helped you out, I could really use brainliest answer.
(It's not something that brainly does, it's something you have to do, as The Questioner.)
<u><em>Good luck on that!</em></u>
22 away from zero because square is times 2
Answer:
Final temperature of the solution is 14°C.
Step-by-step explanation:
Given that,
Initial temperature of the solution, ![T_i=31^{\circ}\ C](https://tex.z-dn.net/?f=T_i%3D31%5E%7B%5Ccirc%7D%5C%20C)
The change in temperature of the solution, ![\Delta T=-17^{\circ}\ C](https://tex.z-dn.net/?f=%5CDelta%20T%3D-17%5E%7B%5Ccirc%7D%5C%20C)
We need to find the final temperature of the solution.
Change in temperature = Final temperature - initial temperature
![\Delta T=T_f-T_i\\\\T_f=\Delta T+T_i\\\\T_f=-17+31\\\\T_f=14^{\circ} C](https://tex.z-dn.net/?f=%5CDelta%20T%3DT_f-T_i%5C%5C%5C%5CT_f%3D%5CDelta%20T%2BT_i%5C%5C%5C%5CT_f%3D-17%2B31%5C%5C%5C%5CT_f%3D14%5E%7B%5Ccirc%7D%20C)
So, the final temperature of the solution is 14°C.
A. (2,6)(5,0)
slope = (0 - 6) / (5 - 2) = -6/3 = -2
y = mx + b
slope(m) = -2
(2,6)..x = 2 and y = 6
sub and find b, the y int
6 = -2(2) + b
6 = -4 + b
6 + 4 = b
10 = b
so line A , equation is : y = -2x + 10
============================
B. (0,2)(6,6)
slope = (6 - 2) / (6 - 0) = 4/6 which reduces to 2/3
y = mx + b
slope(m) = 2/3
(0,2)...x = 0 and y = 2
sub and find b, the y int
2 = 2/3(0) + b
2 = b
LIne B, equation is : y = 2/3x + 2
=========================
so we have :
y = 2/3x + 2
y = -2x + 10
2/3x + 2 = -2x + 10 ..multiply by 3
2x + 6 = -6x + 30
2x + 6x = 30 - 6
8x = 24
x = 24/8
x = 3
y = -2x + 10
y = -2(3) + 10
y = -6 + 10
y = 4
solution is (3,4).....3/4 is the solution to both lines <===
