The answer is the option C.
Here is how you get the answer:
Location A Location B
Truck (129 + 145) / 2 = 137 (94 + 104) / 2 = 99
Car (123 + 101) / 2 = 112 (120 + 142) / 2 = 131
SUV (92 + 128) / 2 = 110 (130 + 134) / 2 = 132
So the matrix is:
137 99
112 131
110 132
The three angles of a triangle add up to 180.
Since you know that two angles add up to 80, you know that the third angle is 100.
Answer:
a=6m
Step-by-step explanation:
x=1, y=2
Solve the following system:
{y = 5 - 3 x5 x - 4 y = -3
Substitute y = 5 - 3 x into the second equation:
{y = 5 - 3 x5 x - 4 (5 - 3 x) = -3
5 x - 4 (5 - 3 x) = (12 x - 20) + 5 x = 17 x - 20:{y = 5 - 3 x17 x - 20 = -3
In the second equation, look to solve for x:{y = 5 - 3 x17 x - 20 = -3
Add 20 to both sides:{y = 5 - 3 x17 x = 17
Divide both sides by 17:{y = 5 - 3 xx = 1
Substitute x = 1 into the first equation:{y = 2x = 1
